Two equal TCP endpoints exchange crossing signals and converge on one connection.

When Both Sides Knocked at Once: TCP's Simultaneous Open

The standard picture of TCP begins with a client knocking and a server listening. The protocol itself has never required that casting. Its original 1981 specification described what happens when two endpoints knock at once: their SYN segments cross, each side becomes both…

AIS’s Shortlist Rule Turns Agenda Time Into Editorial Authority

The AIS 2025 presentation call invited a wide technical community, then made clear that limited programme time would place only shortlisted abstracts on the agenda.

AFRINIC Named Six Regional Bylaws Review Members. Its Appointment Notice Leaves the Reporting Calendar Open

AFRINIC’s 2 March 2026 announcement identifies six Bylaws Review Committee members, one for each listed African sub-region, as well as the chair and secretariat. The linked terms define substantial reporting duties, but the frozen pages do not give dates for progress reports or…

A restarted network host waits behind a translucent boundary while old amber packet trails fade and a separate clean blue connection path becomes safe to use.

The Host That Had to Wait Before Speaking: TCP's Quiet Time After Restart

A restarted machine may look clean precisely because it has forgotten too much. TCP's original quiet-time rule addressed that paradox: if a host lost the sequence numbers used before a crash, it was told to emit nothing for one maximum segment lifetime. Silence was not a repair…

The New RIR Draft Says Enforceability Does Not Wait for the Procedure

Article 1.3 of the new RIR Governance Document draft says a missing common implementation procedure does not stop the document from being enforced. The next clause, added in Version 3, says a decision must still follow the procedure relevant to the entity making it, including any…

AfNOG’s Host-Selection Rules Turn Infrastructure Capacity Into Convening Power

An archived Africa Internet Summit hosting call shows that choosing a host is both an operational-risk decision and a distribution of institutional attention.

A protective hourglass around a closed TCP endpoint is fractured by a red reset reflected from a stateless peer, while a separate guarded path preserves evidence for safe connection reuse.

History

The Reset That Ended Waiting Too Soon: TCP's TIME-WAIT Assassination Hazard

TIME-WAIT looks passive: a closed connection remains in a table while a clock runs down. In 1992, RFC 1337 showed that the state could be destroyed by active protocol behavior. One old segment provoked an acknowledgment; that acknowledgment provoked a reset; the reset erased the…

AfNOG’s NII Service Award Turns Recognition Into a Governance Signal

AfNOG’s published award language does more than celebrate individuals. It identifies service, sustained technical contribution and mentorship as conduct the institution wants its community to value.

AFRINIC Published Five Names for Three Governance Committee Seats. Its Slate Notice Does Not Show Eligibility Assessments

AFRINIC’s final 2026 candidate-slate notice makes the field for three Governance Committee seats visible. It names five people and says the listed candidates were found eligible, but the notice does not publish the candidate-level assessments behind that conclusion.

The Ports That Outlived Their Protocols: RFC 9900 and the Discipline of Giving Numbers Back

Ports 831, 832, and 833 can persist in diagrams, service files, and filters even after the NETCONF transports once attached to them never reached known production deployment. RFC 9900 therefore retires the number bindings without erasing their semantic history.

AfNOG’s Bursary Criteria Turn Travel Funding Into a Knowledge-Sharing Mandate

One Name, Many Rules: RFC 9899 and the Control Surface of Reusable ACL Sets

A security team changes one named prefix set once, and every ACL that references it can inherit the change without rewriting each parent rule. That mechanism is the promise—and the control problem—behind RFC 9899’s reusable policy entities.

A TCP data path passes through an independent middlebox while a small repeating clock drives retransmissions and a larger red deadline arc marks the connection’s final user timeout.

History

The Deadline That Was Not a Retransmission Timer: TCP User Timeout

TCP can decide to retransmit a segment and still decide, on a different clock, that the connection has waited too long. The first decision schedules another attempt. The second ends the connection. RFC 5482 made that persistence preference visible to a peer without turning it…

An IPv6 router connects three host-isolation arrangements: individual routed host islands, separate logical prefix zones on a shared medium, and partial Layer-2 multicast cells, while three incoming pressure streams are filtered differently.

Shrink the Trust Domain: RFC 9898 and the IPv6 Neighbor-Discovery Isolation Choice

On one IPv6 access segment, three different root causes can surface together: multicast load, implicit trust of every on-link node, and router Neighbor Cache Entries created on demand. The practical question is therefore not which symptom to patch, but which part of the Neighbor…

AfNOG’s Sponsor-Visibility Gate Is a Governance Firewall, Not a Branding Rule

AfNOG’s hosting rules make sponsor advertising conditional on advance approval and the event’s non-commercial purpose. That gate is an allocation of authority, not a cosmetic branding choice.

Two endpoints exchange differently colored SYN option envelopes, with later TCP payloads bounded independently in each direction across a separate router path.

History

The Offer That Was Not a Negotiation: How TCP MSS Bounded Each Direction

Each side of a TCP connection can place a four-byte option in its opening SYN. The number does not settle a shared packet size. It says how much TCP data the option's sender is prepared to receive in one segment—a directional boundary that the other endpoint must combine with…

An established blue transport path runs above an amber advertised address; a second path turns green only after a bidirectional authentication and reachability gateway, while a red private-address branch is rejected.

Authenticated Is Not Reachable: RFC 9897 and the MP-DCCP Path-Join Boundary

An authenticated `MP_ADDADDR` advertisement is control data, not permission to send traffic on a new path. That path becomes usable only when `MP_JOIN` binds a new subflow to the original connection and completes the nonce/HMAC reachability handshake.
