Summary

  • NETCONF is working on two ways to make network information less cumbersome to obtain: improving update subscriptions and retrieving long lists in smaller portions.
  • Following approval of its new charter, related drafts have a submission target of 31 December 2026. That is a step in standardisation, not a product launch date.

A network can change while the screen used to watch it is still showing the past. For an operator responsible for keeping a service running, the uncomfortable question is not whether there is enough data. It is whether the information is fresh enough to act on.

That problem sits near the beginning of RFC 7923, the 2016 requirements document behind subscriptions to YANG data. It identifies two jobs that need a continuing view: checking operational state to assure services, and tracking equipment changes to check security-policy compliance. Its argument against periodic polling is practical. Applications needing prompt updates cannot always afford to wait for another request, particularly when communication is unreliable.

The operational implication is a gap in awareness: a service or configuration may have changed before the tool checking it catches up. That is not evidence of a particular missed incident. It explains why making network data easier to obtain is more than tidying up an interface.

Two NETCONF workstreams address that uncomfortable relationship between a network and the tools watching it. Their aim is not simply to collect more. It is to make the exchange more selective: which information, how much of it, and when it arrives.

The cost of asking for everything

List pagination tackles the size of the answer. An application can ask for a portion of a long list rather than retrieve everything at once. For an operator looking for relevant entries, the attraction is straightforward: the application need not first swallow the entire list. The NETCONF charter puts this work within its management remit; whether an implementation delivers the benefit remains a separate test.

YANG-Push addresses the repeated question rather than the oversized answer. An application subscribes to updates from selected data instead of continually requesting fresh copies. RFC 8641 has defined this approach since 2019, with periodic and change-triggered updates. It explains why polling can disappoint: requests can be delayed or lost under network stress, just when the information is most needed. When nothing changes, repeated requests can instead do work for no new insight.

For the person investigating a network problem, those are two different obstacles to getting a useful view. October's news is that the work to improve these methods now has a clearer next step.

From technical problem to December deadline

On 9 October, the IESG approved NETCONF charter 21. The group history records two targets for 31 December 2026: submit YANG-Push enhancement and list-pagination drafts to the IESG for publication as Proposed Standards. YANG-Push is being enhanced, not invented afresh; the target does not announce a performance gain or a finished product.

The milestone entries name subjects, not draft numbers. They give readers a date to watch without identifying the complete submission package.

December is the next submission checkpoint, not proof that every review is finished. The earlier timetable is no longer the plan: July for pagination and November for YANG-Push, entered on 12 June and removed on 18 July. Removing those targets records a change of plan, not completed work.

The approved charter reaches beyond these tasks to NETCONF, RESTCONF, YANG-based management, transports, encodings and supporting models. December offers a checkpoint for two parts of that work. The immediate result to look for is the actual handover of documents; publication, implementation and operational use require their own evidence.

For the operator, the eventual test is whether the view on screen keeps pace with the network it represents. The December handover will not settle that test, but it will show which proposed improvements have moved beyond the working group's desk.
