RedClara built a continental backbone through federation, not ownership

Summary

• RedClara is a non-profit association of national research and education networks based in Uruguay; neither a shareholder company nor a carrier that controls every campus connection.
• Eight core routing nodes and long-term international capacity form a 100G backbone, with reported 100, 200 and 300 Gbit/s links plus a smaller Central American segment.
• ALICE and ALICE2 created the institution and the first network; BELLA secured long-term capacity on the direct Portugal–Brazil route, reducing dependency on North American detours.
• BELLA II must turn project funding into a permanently member-funded network, strengthen weaker national networks and public evidence, and prevent supplier or membership bottlenecks.

BELLA changed the network's geography

BELLA – Building the Europe Link to Latin America – combined a submarine cable component with terrestrial improvements. BELLA-S secured long-term optical spectrum on a direct cable between Portugal and Brazil. BELLA-T strengthened the South American paths over which this capacity travels from the landing point to regional nodes and national networks.

The physical system became EllaLink, an approximately 6,000 kilometre route between Sines and Fortaleza. Research and education traffic entered production in 2021. Two initial 100 Gbit/s links were activated: one between GÉANT and RedClara and one for Copernicus. The 2024 report describes a broader BELLA infrastructure of 35,830 kilometres and Nx100G capacity, i.e. substantially more than the submarine segment alone.

Lengths and costs measure different boundaries. CORDIS shows approximately €12.4447 million total cost and €10 million EU contribution for the BELLA-S1 action, while other totals include terrestrial work, additional funding lines and national contributions. They must not be merged into a single value without explanation.

Programme sources cited latency reductions of up to 50 per cent on certain paths. This statement must be limited to specific routes; it is not a universal result. The lasting gain is a direct South Atlantic route with capacity rights that can be expanded with optics and demand.

Forty optical channels do not mean ownership of the cable

BELLA acquired long-term rights to forty optical channels of EllaLink. A spectrum right allows control over how capacity is activated and upgraded; however, it does not make RedClara or GÉANT exclusive owners of the commercial cable, landing stations or supporting facilities.

The chain runs from fibre pair to spectrum right, from spectrum to optical channels, from channels to coherent 100G or later transmission, and from the landing station into the terrestrial networks. The cable operator maintains the marine system; other organisations operate landing and colocation; RedClara and GÉANT coordinate academic capacity; vendors supply equipment; NRENs bring traffic to the facilities.

Spectrum rights can be more valuable than a fixed circuit because capacity can grow within optical and contractual limits through equipment replacement. At the same time they expose the consortium to shared governance, repair, power, spectrum planning and interoperability. The right is long-lived but not self-sustaining.

This boundary matters. RedClara can rightly speak of a regional backbone and a transatlantic route because it coordinates and operates capacity. It should not be described as the owner of every line on the map. Its strength comes from federation and contractual control of strategic capacity, not from complete physical integration.

BELLA and the direct South Atlantic route

BELLA changed the geography of Europe–Latin America research connectivity. Before the direct route, traffic could flow through North America even though the endpoints were geographically further south. Sines–Fortaleza created a shorter alternative for many paths and a long-term asset for research communities.

The benefit is not a blanket promise of halved latency. The gain depends on source, destination, national access, load and return path. The claim “up to 50 per cent” belongs to specific programme paths. The more robust statement is route diversity: the core Europe relationship is no longer exclusively tied to North American gateways.

This benefits large data transfers, astronomy, Earth observation, distributed computing, academic telemedicine and interactive collaboration. RedClara also gains as an interconnection platform, because projects can obtain predictable private capacity rather than only best-effort internet.

The direct connection remains vulnerable to cable cut, power, station, equipment and maintenance failures. Resilience demands alternative paths, tested failover and sufficient capacity via Miami or other routes. “Direct” improves the architecture but does not replace redundancy.

BELLA was also a long-term institutional partnership between Europe and Latin America. The capacity was created within a research cooperation programme, not as an ordinary transit contract. This gives the community greater influence over use and upgrade, even though commercial providers remain core dependencies.

A continental network that is not a single network

RedClara is most easily misunderstood when it is described simply as Latin America’s research network. The term suggests a single operator exercising direct control from the international backbone to a university’s wall socket. In reality the architecture is federated. Researchers usually reach RedClara through their institution’s network and then through a national research and education network, an NREN. RedClara provides the regional and intercontinental layer through which these separately managed systems function as part of a larger scientific environment.

This distinction determines both the organisation’s value and its limits. Brazil’s RNP, Chile’s REUNA, Colombia’s RENATA, Ecuador’s CEDIA, Mexico’s CUDI, Costa Rica’s RedCONARE and Uruguay’s RAU retain their national governance, domestic infrastructure, relationships with institutions and their own operational responsibilities. RedClara does not replace them. The organisation connects them, represents common requirements, coordinates capacity and services, and provides access to partner networks such as GÉANT, Internet2 and CANARIE.

A typical end-to-end path may therefore traverse a campus LAN, an institutional firewall, a national access circuit, the NREN backbone, RedClara, an international peer, the destination NREN and finally a remote research facility. A regional 100 Gbit/s path cannot compensate for a congested campus edge, a slow national link, misconfigured storage or restrictive destination policies. Conversely, a national network cannot alone negotiate every intercontinental route, identity relationship and collaboration service that modern science requires.

The accurate description is therefore: RedClara is a shared coordination and infrastructure layer. “Shared” refers to governance, engineering, long-term capacity rights and common services, not to ownership of every fibre, router, point of presence or cable segment on the map.

Why Latin America needed a regional layer

The starting problem was fragmentation. In the early 2000s several Latin American states had national or emerging academic networks, but no permanent continental organisation that could aggregate demand, operate a regional backbone or negotiate on equal footing with European and North American networks.

A university could be well connected domestically yet remain dependent on expensive, indirect international transit to collaborate with another Latin American institution. Traffic between Europe and Latin America could flow through North America because the existing cable and interconnection structure made that path easier to procure.

A centralised continental carrier would not have been a realistic solution. The region displayed wide differences in NREN maturity, public funding, regulation, fibre availability, higher education systems and international landing points. National organisations had to retain their legal and operational autonomy. The viable model was therefore a federation: domestic networks kept their national roles while a regional association coordinated the shared layer and represented them to global partners.

Toledo, Valle de Bravo and the legal association

The institutional idea took shape in 2002. Representatives of Latin American NRENs discussed the feasibility of a regional network during a CAESAR meeting in Toledo and continued the work in Rio de Janeiro, Buenos Aires, Santiago and Mexico. It was not only about topology. They needed to settle participation, the relationship between regional and national levels, decision‑making procedures and the question of how an externally funded project could become a permanent organisation.

The legal chronology contains three dates that should not be merged into a simplified founding day. According to RedClara’s history, the statutes were signed on 9 June 2003 in Valle de Bravo, Mexico. A civil society registry of the Organization of American States records 10 June 2003 as the date of establishment. RedClara also states that legal existence was recognised on 23 December 2003 under Uruguayan law. These dates are to be treated as connected but distinct events: constituent agreement, administrative record of establishment and later legal recognition in Uruguay.

RedClara can best be described as a non‑profit international civil association recognised under Uruguayan law with its seat in Montevideo. The organisation occasionally uses the English phrase “international law organisation”. The available statutes and registry documents, however, do not attest to foundation by treaty or the legal personality of an intergovernmental organisation. RedClara is a membership association with regional goals, not a supranational regulator or authority.

The current statutes were approved in November 2019 and published in January 2020. They designate the General Assembly as the supreme body, establish a Board of Directors for management, an Audit Committee for oversight, a Technical Commission with NREN expertise and an Executive Directorate for implementation. The network’s legitimacy comes from membership and cooperation, not from shareholding or territorial authority.

Seven members, eleven connected countries and a larger mission

The current public membership directory lists seven NRENs: RNP, RENATA, RedCONARE, REUNA, CEDIA, CUDI and RAU. The current advanced connectivity page, by contrast, states that the network connects eleven countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Mexico, Paraguay and Uruguay. Older materials speak of thirteen countries. These numbers are not interchangeable.

Legal membership determines governance rights, obligations and participation in the association. Operational connectivity can exist through partners, transitional arrangements or projects even if the national network concerned is not a full voting member. Historical country counts may reflect former members or older programme reach.

The gap creates a strategic tension. RedClara aims to serve a wider region than the one that formally governs the association. A country can benefit from connectivity or a BELLA II programme without having an equal seat in the General Assembly. Conversely, the seven members bear a disproportionate share of governance, technical work and possibly recurrent funding.

The 2025–2027 Board reflects the active legal membership base. José Palacios of REUNA is President, Eduardo Grizendi of RNP Vice President, Juan Pablo Carvallo of CEDIA Treasurer, Carlos Gamboa of RedCONARE Secretary and Eduardo Grampín of RAU Board member. Luis Eliécer Cadenas is Executive Director. The structure gives the national networks formal control; however, current assembly minutes, voting weights, contribution rates and a full explanation of how connected non‑members are involved in key decisions are publicly absent.

ALICE provided the seed capital for a regional network

The legal formation of RedClara and the first operational network were inseparable from ALICE, the project for interconnection between Europe and Latin America. The European Commission and DANTE signed the contract in June 2003. The programme had €12.5 million: €10 million from the Commission and €2.5 million from Latin American partners. After extensions it ran until March 2008.

ALICE solved several initial problems at once. It provided capital, created common procurement, gave the new association an immediate operational task and connected the region to GÉANT. Instead of waiting for a mature contribution and revenue model, the network’s utility could be demonstrated while the institution itself was still being formed.

The first infrastructure was modest compared with today’s, but institutionally decisive. It created regional PoPs and production links between NRENs. At the same time it connected Latin America with European and North American research networks and established technical relationships that later encompassed identity, middleware, grid computing, open science and joint projects.

ALICE also inscribed a difficult question into the model: what happens when time‑limited funding finances infrastructure that is meant to work permanently? Contracts, equipment, teams and expectations do not disappear with the final report. The subsequent history of RedClara is the search for longer investment horizons – IRUs, fibre, wavelengths, spectrum, services and co‑investment – that can carry the institution between funding cycles.

ALICE2 shifted coordination to Latin America

ALICE2 began in December 2008 on the basis of a European Commission contract worth €18 million. The decisive institutional change was that RedClara took over coordination instead of merely participating in a programme led by Europe. This moved operational and project leadership to the Latin American association.

The programme explicitly targeted sustainability: lower recurrent costs through dark fibre, wavelengths and IRUs, broader coverage, stronger NRENs, technical training, user communities and more stable funding. Sources differ between an end in 2012 and an administrative closure in January 2013. The safest portrayal is that operational activities ended before the final administrative closure.

ALICE2 also broadened the definition of infrastructure. Grid initiatives connected regional resources with international collaborations. Identity and middleware projects facilitated authentication and access to shared services. Training measures acknowledged that a fibre route is of little use if national networks lack the staff, governance or applications to use it.

The programme took RedClara from a young transport infrastructure to a regional e‑infrastructure organisation. Dependence on external funding persisted, but the organisation gained experience in managing large programmes, coordinating technical work across countries and turning transport into a service platform.

From short‑term circuits to long‑term capacity rights

The economics of a regional network depend on how capacity is procured. A short‑term managed circuit provides a defined service but exposes the operator to price renegotiation and limits control over upgrades. A long‑term right to fibre, a wavelength or spectrum demands more initial investment and governance but permits long‑term planning and modernisation of transmission without having to buy each capacity step anew.

RedClara’s strategy therefore shifted, wherever possible, towards IRUs, dark fibre, wavelengths, optical channels and capacity swaps. The organisation did not become a classic owner of all cables, but it acquired rights that can outlast a technology generation.

Long‑term rights also change the risk. They reduce recurrent procurement but increase dependency on the cable, landing station, operator, maintenance and contract. Spectrum has value only if the system is repaired, powered and operated. Optical equipment, colocation, terrestrial extensions and skilled teams remain necessary.

The asset base therefore cannot be depicted as a simple ownership map. Some fibres belong to NRENs, others are leased, contributed in kind, secured by IRUs or represented by optical rights in a shared cable. The regional platform is assembled as much from legal and technical relationships as from physical assets.

Before BELLA, Europe often meant North America first

The absence of a direct, high‑capacity route between Europe and Latin America shaped performance and dependency. Even between institutions on opposite sides of the South Atlantic, traffic could flow through commercial systems in North America. For carriers this path was understandable, but it lengthened the distance, concentrated transit and limited science’s control over capacity.

The North American interconnection was and remains essential. Initiatives such as WHREN/LILA strengthened routes between Latin American networks and the United States. Miami became a gateway to Internet2, CANARIE and other partners. These paths provide reach and contribute to resilience.

The problem was dependency, not the existence of these routes. A continental network needs alternatives. A direct link to Europe could lower latency for certain pairs, diversify failure paths and carry large scientific data flows without forcing everything through the same corridor.

With Earth observation imagery, genomics, telescope data, climate models and HPC workloads, this need became more pressing. BELLA turned the goal of a direct route into a long‑term physical and contractual system.

Today’s topology: eight nodes and several kinds of capacity

The current technical description lists eight core routing nodes: Buenos Aires, Fortaleza, Porto Alegre, São Paulo, Santiago, Manta, Panama City and Miami. The South American NRENs reach one of these points, which are connected by a ring of 100 Gbit/s or more. The shared Central American infrastructure is stated to carry 20 Gbit/s. Fortaleza is the main direct path to GÉANT and on to European and African partners; Miami is the principal gateway to Internet2, CANARIE and North America.

The connectivity page also mentions 100, 200 and 300 Gbit/s links, eleven connected countries and more than 1,300 institutions. The same website still contains older 10 Gbit/s language. The newer technical information supports a 100G‑class network; the 10G statement is to be treated as documentation legacy.

Not every path has the same usable capacity. Line rate, protected aggregate, reserved capacity and bandwidth actually delivered to a member are different quantities. Moreover, a logical ring may share physical routes or carrier infrastructure and is therefore not automatically fully diverse.

Manta strengthens the Pacific side, Fortaleza the South Atlantic and Panama or Miami the Central American, Caribbean and North American connections. The geometry follows landing stations, telecommunications markets, national partners and available fibre.

The figure of more than 1,300 institutions is a reach metric without a published methodology. It does not say how many institutions are active, at what speed they are connected or which regional services they use. Maturity should be measured by capacity, usage, availability and service quality, not by a single aggregate total.

AS27750, peering and the separation of traffic classes

AS27750 is RedClara’s public Autonomous System identity. Through it the organisation carries or exchanges routes for member networks, research peers and international services. Public routing databases show relationships with GÉANT, ESnet, Internet2, CANARIE, RNP, REUNA, RENATA, RedCONARE, CEDIA and TENET. Such data are snapshots, not a complete contractual or topological list.

“Advanced internet” does not simply mean faster public internet. Eligible research traffic can be routed over private or dedicated paths to NRENs, data centres and instruments instead of using general transit.

At the same time RedClara offers separation from the commercial internet, peering and global connectivity. Universities need both academic destinations and the public internet. These traffic classes may have different suppliers, policies and billing. The research network is therefore not physically isolated from the internet; the boundary arises from eligibility, routing and capacity.

Selective peering enables direct connections where mutually beneficial, but does not guarantee every network a session. Presence in Miami or São Paulo facilitates interconnection but still requires ports, cross‑connects, filters, routing policies and operations.

A complete current statement of RPKI validation, ROA coverage, IRR filtering, route‑leak protection, BGP communities and per‑peer availability is publicly absent. More verifiable routing security information would make resilience better assessable without revealing sensitive details.

Layer‑2 circuits and distributed responsibility

The portfolio includes dedicated virtual Layer‑2 connections. A VLAN can connect laboratories, data centres or instruments in multiple countries as if they were on the same Ethernet segment. This is useful for large data transfers, distributed experiments or specialised applications.

Such a circuit traverses several administrative domains. The institution provides the local port, the NREN transports to the regional network, RedClara coordinates the international stretch and the far end repeats the path. VLAN IDs, MTU, redundancy, bandwidth, addressing, security and change windows must match everywhere.

As a result, operational responsibility is distributed. A fault can lie in the campus, the NREN, RedClara, the transport provider or the destination. A regional NOC needs clear circuit identification, 24‑hour contacts, demarcation points and escalation rules.

RedClara names engineering, NOC and security groups, but does not publish a comprehensive SLA methodology, historical repair times or an independent incident database. The federated principle remains: RedClara coordinates the regional segment and works with NRENs, but cannot guarantee every component.

BELLA II: expansion through co‑investment, not a ready‑made map

RedClara and the European Commission signed BELLA II on 14 December 2022. The programme is designed for 48 months, with a €13 million Commission contribution within a €28 million plan. At least €15 million is to be mobilised from governments, development institutions, companies, banks and other partners.

Goals include connecting or strengthening Peru, Costa Rica, El Salvador, Guatemala and Honduras, as well as possible extensions to Mexico, the Caribbean, Paraguay, Uruguay, Bolivia and Belize. This list describes objectives and dialogues; it does not prove that every country was productively connected as of the reference date of 3 August 2026.

The Competitive Dialogue opened in 2025 and called for a fibre model with a minimum 15‑year life, at least 20 Gbit/s in Central America and 100 Gbit/s in Peru, plus a growth path. Proposals may include existing fibre, new build, capacity swaps, co‑investment or combinations.

Flexibility can attract investment but weakens accountability. It must be clear who builds, owns, maintains and pays, what capacity is dedicated to research, how a country joins and what happens after funding ends. A 15‑year right is permanent only if operations, power, optics and upgrades are also financed.

BELLA II should be measured by commissioned routes, enforceable rights, accepted traffic and post‑project rules. Memoranda and policy dialogues are progress, but not a live connection. Separating announcement from commissioning protects credibility.

From transport network to regional research platform

The first RedClara generation proved that national research networks can exchange traffic over a regional backbone. Later the follow‑on question arose of which shared capabilities build on it: identity, file transfer, collaboration environments, training, HPC access, open science, cybersecurity and thematic communities.

This is not a departure from networking, but rather an increase in value. A fast path helps little if researchers cannot log in, cannot find a compute resource, cannot transfer data, cannot identify partners or receive no support. Application and community layers turn raw capacity into usable research infrastructure.

BELLA II formalises this platform logic with innovation hubs, testbeds, open calls, training, dialogues and partner or funding searches. The Agrifood Ideathon 2024 brought together 125 professionals from 28 countries; first HPC testbeds linked training and prototyping with shared computing.

A testbed is not a production service. It typically has a selected cohort, limited capacity, specialist support and an experimental goal. It can uncover barriers, but creates false expectations if a demonstration is portrayed as general availability.

RedClara’s opportunity is a federation of services and test environments. However, this increases responsibilities for software operations, data protection, support and lifecycle. NRENs, SCALAC members, universities, clouds and project partners run the underlying resources; RedClara integrates and provides the regional access path.

BIO+IA and the discipline of early‑adopter evidence

BIO+IA Early Adopters is a clear example of this platform role. The programme, opened in 2026 under BELLA II, selected five projects from six countries for training, expert assistance and access to an AI and bioinformatics test environment. Topics included breast cancer biology, molecular screening, antimicrobial or mercury resistance, drug repositioning for liver disease and translational biomedicine.

At the Demo Day in July 2026 teams reported that the environment accelerated searching, integrating and interpreting biological information. This is meaningful evidence of supported research workflows and that network, tools and expertise can be combined regionally.

It does not prove clinical efficacy. An identified molecule is not an effective therapy; a faster bioinformatics process does not replace laboratory validation, regulation or care delivery. The cohort was limited, and the results come from entities and organisers, not from independent clinical trials.

A demonstration becomes infrastructure when teams can return, new cohorts are admitted, data rules are clear, computing and storage resources remain funded and successful workflows migrate into national or institutional systems. Repeated use, publications, independent assessment and post‑pilot funding are the relevant signals.

Identity as infrastructure: FIEL, eduGAIN and eduroam

A network path is worthless if a researcher cannot prove her identity at the destination. FIEL supports national identity federations; eduGAIN exchanges metadata between federations and enables international access via the home institution; eduroam offers a related roaming model for network access.

These systems do not build a regional password database. In a federated login, a service redirects to the home institution. That institution authenticates and delivers a signed assertion or selected attributes; the service applies its own access policy. RedClara strengthens the federation and connects it to the global trust space, without normally receiving passwords.

Trust and risk are distributed. Universities retain responsibility for user accounts; researchers can use one identity across repositories, computing platforms and tools. However, assurance levels differ, metadata can become stale, attributes can be interpreted differently and a compromised identity provider can affect multiple services.

eduGAIN solves discovery and metadata exchange, not every legal and policy question. Services decide which institutions and assurance levels they accept; institutions protect keys, manage accounts and respond to incidents. Cross‑border use involves consent, data minimisation and legal basis.

With eduroam the visited institution provides access and forwards authentication through a RADIUS hierarchy to the home institution. Security depends on correct endpoint configuration, certificate validation, home identity and local controls.

Identity is part of infrastructure continuity: a supercomputer can be reachable at the IP level and yet inaccessible to the intended user if the trust chain fails. RedClara thereby addresses a failure that a pure transport network would leave outside its scope.

MiLab, eNVIO and the collaborative research layer

MiLab bundles open‑source tools behind federated access: a Dataverse‑based data environment, GitLab for development, Mattermost for communication and notebook resources with JupyterHub, Python and R. Together they accompany a team from communication and code to analysis, data curation and publication.

Distributed groups often assemble these functions from separate services with different accounts, data rules and support models. A regional workspace can reduce fragmentation and create a shared environment for institutions and countries.

MiLab is not a universal regional cloud. It does not automatically provide large‑scale HPC, unlimited storage, certification for every sensitive data type or permanent legal archiving. Capacity, service levels and hosting may change and must match security, data and performance needs.

eNVIO addresses the transfer of large files over academic infrastructure. Email and consumer sharing are unsuitable for many scientific datasets. The real value depends on size limits, retention, encryption, support and NREN integration, which are not yet fully quantified publicly.

Regional training platforms and a learning management system developed with CEDIA translate know‑how into courses and certification. Training is necessary, but does not replace funded positions, production experience and institutional responsibility.

The collaboration layer shows the model in miniature: RedClara integrates tools and access, NRENs bring users, institutions bring identity and context, researchers do the work. Success demands clear responsibilities; the platform cannot compensate for every local gap in staffing, data governance and application support.

Ventanilla Abierta and navigating a fragmented ecosystem

Regional research infrastructure can be hard to find even though it exists. Researchers may know that HPC, storage, identity or specialised networks are available somewhere in Latin America, but not who runs them, whether their project is eligible or how an application begins. Ventanilla Abierta was created as a central advisory layer for this problem.

The service does not own every resource to which it refers. It translates a research need into a path through the ecosystem: connectivity via an NREN, computing via SCALAC or another centre, data and storage services, identity federation, international partner resources or project and funding pathways. The value lies in coordination and findability.

Ventanilla Abierta thereby becomes navigation infrastructure. Physical capacity often goes unused not for lack of demand, but because institutional interfaces are fragmented. If an application requires knowledge of multiple NRENs, programmes and technical teams, the regional option may be abandoned. A guided front door lowers transaction costs.

Funds and Partners addresses the related need for calls, complementary institutions and funding. A technical idea becomes a project only when partners and resources come together.

The limit is authority. RedClara can advise and connect, but cannot guarantee another institution’s capacity, approval, budget or schedule. A referral is not a reservation, a call is not an award and an introduction is not a consortium agreement. Success is measured by functioning handovers and continued projects.

LA Referencia, SCALAC and the shared knowledge and computing chain

RedClara’s relationships with open science and high‑performance computing show how transport becomes an ecosystem. LA Referencia aggregates metadata and research outputs from national repositories. SCALAC links advanced computing organisations. Both are independent alliances, not RedClara subsidiaries; the regional linkage and coordination, however, enable cross‑border work.

The open‑science chain begins in the institution. Researchers deposit publications or datasets according to local rules, national systems organise metadata and access, LA Referencia creates regional discovery and interoperability, and relationships with, for example, OpenAIRE open a larger international environment. RedClara supplies connectivity and institutional linkage, not ownership of all repositories or results.

Open science needs more than bandwidth. Metadata quality, persistent identifiers, licences, repository governance, long‑term preservation and incentives determine whether an output is findable and reusable. A fast network does not make an undocumented file reproducible.

SCALAC solves a similar coordination problem for HPC. Resources are spread across universities and national centres. A regional alliance makes them visible, pools expertise and enables testbeds or training that a single country would struggle to provide.

An HPC federation is not a single supercomputer. Schedulers, software stacks, access rules, queues, storage and billing differ; data must be staged, users authenticated and allocations governed. Sensitive workloads may be subject to cross‑border restrictions.

Strategically this creates options: countries can participate without funding every specialist resource themselves. The risk is episodic project access rather than a predictable service with published capacity, eligibility and cost rules.

Health, Earth observation and communities that give the network purpose

RUTE-ALC connects university telemedicine and digital health communities. Possible applications range from specialist consultation and medical education through image exchange and standards to emergency cooperation and digital health governance.

A research network can provide reliable paths, identity and collaboration, but it does not thereby become a healthcare provider. Clinical data protection, medical device regulation, professional responsibility and patient consent remain with health institutions and authorities. A capable connection is a prerequisite, not a complete clinical service.

Copernicus Academy in Latin America creates another sectoral bridge. Earth observation data can support agriculture, disaster management, climate adaptation, ocean monitoring, water, forestry, urban planning and energy. RedClara helps with data transport and training; the bottleneck is often analytical capacity rather than access to raw imagery.

TICAL brings together higher‑education IT leaders and technical communities. According to the annual report, more than 200 people attended in Rio de Janeiro in 2024. Such meetings are not physical infrastructure, but they help align procurement, security, cloud, identity and service priorities among institutions that will later interoperate.

These communities show why a research network is not merely a discounted carrier. Recurrent relationships create trust for projects and incidents. Nevertheless, attendance does not prove implementation; a workshop does not create national capacity, and a connection does not demonstrate a health or climate outcome.

EduLACSeg and the regional security trust network

Cybersecurity coordination suits a federation because academic institutions face similar campaigns across borders. eduLACSeg provides a trust framework for indicators, context and response experience. A threat can be detected once and shared with multiple countries before each institution discovers it separately.

In July 2026 threat intelligence originating from CERN was distributed via RedClara to RNP, REUNA, RENATA, RedCONARE, RAU, CUDI and CEDIA. This is concrete evidence of a regional intelligence chain. RedClara’s characterisation as Latin America’s largest academic cybersecurity ecosystem remains a self‑description in the absence of an independent comparative definition.

Threat sharing is not automatically right or safe. Indicators can be false, stale or context‑dependent; attribution can be uncertain; data‑protection and confidentiality rules differ; response capabilities range from a mature SOC to a small team. Distribution is not the same as uniform response.

The 2024 report mentions LAC4 training with 85 entities from nearly 60 organisations in 18 countries, 30 per cent of whom were women, as well as a Security Baseline Bootcamp with RNP and GÉANT at TICAL2024. These are capacity signals, but not proof of identical implementation.

RedClara’s routing, identity metadata, platforms and testbeds must also be protected. A complete current public methodology on RPKI, ROA coverage, IRR filtering, incident disclosure and response times is absent. Lasting trust requires rules for classification, sharing, data protection, attribution and post‑incident learning, as well as measurable technical controls.

SUBMERSE and the network as a scientific instrument

SUBMERSE explored how operational telecom fibre can itself become a sensor. Distributed Acoustic Sensing uses optical pulses and backscattered light to detect small disturbances along the fibre, whether from earthquakes, ocean movement, traffic or other events.

The idea turns existing routes into an observation platform, even where dedicated sensor networks would be expensive. Research networks can connect scientists with cable owners, landing stations, data and computing.

A fibre does not automatically become an observatory, however. Instrumentation, access, calibration, time synchronisation, storage, processing and scientific validation require concrete agreements. Measurement and production traffic must coexist without harming reliability; data can reveal sensitive activity.

RedClara was a consortium partner, not owner of all fibres or sole inventor. The core funded project cycle concluded with closing activities in 2026. SUBMERSE should therefore be described as a demonstration and a direction of cooperation, not as an already permanent regional service.

If later phases secure rights, standards, funding and users, fibre sensing could give RedClara a distinctive role in geophysics, ocean research and resilience. Then the infrastructure would generate scientific value not only through transported data, but through its own measurements.

An ecosystem of partners, not a collection of subsidiaries

The relationship network stretches from national NRENs, the European Commission, GÉANT, Internet2 and CANARIE, through development banks, EllaLink and carriers, to SCALAC, LA Referencia, RUTE-ALC, LNet/LACChain, universities and specialist communities. These relationships are legally and operationally distinct.

An NREN is a member, an operational partner, or both. GÉANT and Internet2 are peers. The Commission funds programmes. EllaLink is commercial infrastructure with acquired rights. SCALAC, LA Referencia and RUTE-ALC have their own governance. A university can be a user, host, beneficiary or knowledge partner.

Subsuming everything under “RedClara” would overstate central control and blur responsibility. The value lies precisely in coordinating assets and institutions that the association does not own. Serious portrayal distinguishes membership, funding, capacity, interoperability, implementation and project participation.

The ecosystem avoids a single owner but can diffuse accountability. When a failure occurs it must be clear whether the campus, the NREN, RedClara, a carrier, a platform or an international partner is responsible. Federation is robust when boundaries are visible.

Funding from membership, projects and capacity rights

RedClara has no demonstrated shareholders, market valuation or distributable profits. The statutes permit membership fees and other means. These are supplemented by consulting and service revenue, EU and development projects, international cooperation, partner contributions, co‑investment, capacity swaps and in‑kind contributions.

The best‑known figures are programme budgets, not organisational revenues. ALICE covered €12.5 million, ALICE2 €18 million, BELLA various actions and BELLA II a plan of €28 million with €13 million EU contribution and at least €15 million to be mobilised. These amounts must not be added together and presented as turnover.

Considerable value resides in spectrum rights, IRUs, national fibre, colocation, equipment and seconded staff. Their worth depends on duration, maintenance, upgrade rights and restrictions, not just on project volume.

The 2024 annual report describes programmes and personnel, but does not include complete current audited accounts with a balance sheet, reserves, contribution concentration and supplier exposure. An exact current headcount is also absent. This limits sustainability analysis.

The core risk is the time horizon: grant projects last years; the backbone, identity and platforms must function indefinitely. Long‑term rights help, but operations, power, equipment, support and staff need recurrent funding. Sustainability demands contributions, cost recovery, national participation and partnerships, without treating project money as permanent revenue.

The last mile is national, institutional and unequal

A continental backbone can be technically impressive while its utility remains unevenly distributed. Countries differ in domestic fibre, NREN funding, government support, carrier competition, landing stations, higher‑education capacity and skilled personnel. Within a single country a leading university may be excellently connected while a remote institution has a fragile link.

RedClara can aggregate demand, negotiate capacity, offer training and demonstrate the value of an NREN. It cannot replace national investment, every regulatory hurdle and every access circuit. The last mile remains the job of institutions, NRENs and national providers.

A “connected country” therefore does not mean equal quality. More than 1,300 institutions measures reach, but not methodology, bandwidth, availability or usage. Mature metrics would distinguish institutions that are listed, active, connected by capacity and using regional services.

BELLA II can expand reach while also creating obligations in countries with weak operational capacity. Sustainable inclusion needs local engineering, budgets, support, security and identity integration. An international link without a strong NREN can remain a high‑capacity island.

Documentation debt hides operational maturity

RedClara’s public archive is rich but contradictory: seven members, eleven connected countries and an older thirteen; modern 100G description alongside 10G text; institution, traffic and availability figures without uniform methodology.

The likeliest explanation is documentation debt. Pages from several generations remain online simultaneously. This does not refute the modern network, but it forces scrutiny of source, date and definition. In infrastructure, outdated documentation can be an operational risk, not just an editorial problem.

A topology should state date, contractual and usable capacity, protection, operator, commissioning status and right type. Traffic statistics need period, direction and aggregation; availability needs scope and formula; membership needs to separate governance, connection and project participation.

More coherent publication would help members, funders and users, and prevent memoranda being read as active routes. Transparency does not require revealing security details, but precise definitions.

RedClara’s achievement is federation at infrastructure scale

The central achievement is not a single cable, a single router or a single programme, but a lasting regional mechanism: autonomous national networks aggregate demand, operate interconnection, acquire long‑term rights, participate in global projects and build shared services without giving up their national governance.

ALICE turned the idea into a network. ALICE2 shifted coordination and sought sustainability. BELLA changed the geography with a direct route and spectrum. BELLA II tries to expand reach and move transport into identity, open science, computing, security and experimentation.

The federation also defines limits. RedClara does not own every asset, does not control every NREN, does not guarantee every last mile and does not have unlimited resources. Its power is coordination: strong when incentives are aligned, weak when responsibility is diffuse or national capacity is limited public evidence.

Future relevance depends less on a new speed record than on the institutional quality around the capacity: more representative membership, long‑lived contracts, transparent finances, measurable security, service lifecycles and clear paths from pilot to production. The backbone is the foundation; the federated institution is the strategic asset.

Indicators that BELLA II becomes durable infrastructure

The first signal is commissioning. Memoranda, dialogues and tender requirements need to lead to named suppliers, accepted routes, live traffic, incident procedures and public data. Capacity should separate minimum value, line rate, protected aggregate and usable bandwidth. A 15‑year target counts only with viable operations, maintenance and upgrade rights.

The second signal is membership. Seven public members face eleven connected countries. One must watch whether target countries become members, permanent partners or institutional entities, and how status affects voting rights, contributions, services and obligations. Wider reach without broader recurring governance increases the load under concentrated control.

The third signal is operational evidence: dated topology and traffic data, SLA methodology, incident disclosure, routing security, RPKI and measured diversity between EllaLink, Miami and alternatives. A cable cut or route leak will show whether the logical diversity is real physically and in policy terms.

The fourth signal is service conversion. BIO+IA, HPC, MiLab, identity, eduLACSeg and open science should be measured by repeat users, production allocations, support, data rules and post‑grant funding. A pilot becomes infrastructure when users can reliably plan around it.

The final signal is finances. Current audited accounts, reserves, contribution and supplier concentration, and unrestricted versus restricted funds would increase credibility. What matters is whether RedClara can sustain capacity and services between European funding cycles without turning weaker NRENs into temporary project beneficiaries.

Evidence‑based scenarios

In the successful expansion scenario, Peru and the Central American NRENs gain long‑term, scalable routes. Direct Europe links, North American gateways and Pacific access support larger instruments and shared computing.

In the service‑federation scenario, connectivity becomes less visible because identity, security, data, HPC and testbeds become everyday products. Value rises, as do software, data‑protection and support obligations.

In the concentrated governance scenario, legal membership stays at seven while projects and connections grow. RedClara would be operationally regional but dependent on a small core for representation, cost and succession.

In the project‑cycle scenario, innovations regularly start with grants and struggle for survival after closure. The backbone remains; higher services fluctuate with programmes. This is the central negative scenario without a permanent cost model.

Carrier co‑investment can improve sustainability through swaps, joint build and long‑term rights, but it deepens dependency on a few suppliers and demands strict maintenance, exit and upgrade rules.

In the network‑as‑instrument scenario, SUBMERSE methods are extended to more regional fibre, generating environmental and geophysics services. This is still prospective, but could give RedClara a distinctive scientific role.

Who controls the system and who bears the risk?

Control is distributed. Member NRENs steer the association and its Board; the Executive Directorate and technical groups implement regionally; national networks control domestic infrastructure; peers control their own networks; funders shape programmes; carriers, cables, colocation and equipment vendors own the physical dependencies; universities generate demand but do not always hold direct regional governance rights.

This prevents a single owner, but decouples decision and consequence. A Board can approve a programme whose last mile is paid for by an NREN; a funder defines four years, members inherit decades of maintenance; a carrier may hold the only practical route; a user may not know who repairs. These interfaces are the most important control surface.

Incentives should make permanent contributions visible: fees, fibre, staff secondment, service operation, data stewardship and security response. Expansion countries need a path to national responsibility and recurring obligations; strong members need assurance that solidarity does not become unlimited cost shifting without accountability.

Supplier contracts must secure route diversity, upgrade rights, auditability, exit and continuity upon change of ownership or strategy. Long‑term rights reduce price risk but can become worthless if a station, optics or maintenance fails. The most important decision is not just the bandwidth bought, but which dependencies become hard to reverse.

Decisions that cannot wait for the next grant

First, RedClara must decide whether it wants to be primarily a connectivity federation or a permanent operator of shared digital platforms. MiLab, identity, security and AI testbeds create value, but also data, software, staffing and liability obligations. Permanent services need owners, lifecycle funding, incident response and decommissioning rules.

Second, the gap between legal membership and operational reach must be resolved. Connected countries need status, a voice and a path to membership or another accountable arrangement. Informality eases expansion but leaves open who governs, pays and can exit.

Third, financial transparency must become a governance instrument. Accounts, reserves, contributions, restricted funds and supplier concentration determine whether the network and its services survive a funding interruption or a cable emergency.

Fourth, a published continuity architecture is needed: route diversity, incident escalation, configuration and registry backups, identity and platform recovery, cable alternatives and succession of grant‑funded services. Critical functions must survive the failure of a grant, a supplier, a path or a national partner.

The irreversible risk is accumulating critical services and long‑term dependencies faster than recurring authority, funding and operational evidence. The irreversible opportunity is turning BELLA rights, NREN governance and global partnerships into a regional infrastructure commons that no single country could build. Distributed control must be preserved, but accountability must become explicit.

The long‑term significance of a shared regional backbone

RedClara demonstrates a form of infrastructure sovereignty through cooperation rather than isolation. Latin American science gains room for manoeuvre because national networks jointly control a regional layer, hold strategic long‑term capacity and face global partnerships with greater balance. Commercial dependency remains, but mission, routing and upgrades are not wholly left to the general internet market.

The model is relevant beyond the research sector. It shows how smaller or unevenly resourced institutions can aggregate demand without abandoning national autonomy, and how grant funding can be converted into rights and organisations that outlive a project. It also shows the limits: coordination cannot indefinitely compensate for weak domestic networks, opaque finances and unclear accountability.

The decisive choice is whether the next phase merely extends the map or matures the institution. More countries and faster links matter, but the lasting asset is the system of governance, operations, identity, data, security and scientific cooperation. If it becomes transparent, financially resilient and genuinely regional, RedClara will remain one of Latin America’s most important shared digital infrastructures. Otherwise the backbone may continue carrying traffic while the higher ambitions depend on the next externally funded programme.
