Discussions - February 2026 (Boulder Interim)

February was dominated by the Boulder interim meeting and associated hackathon (Feb 9-12).

Boulder Interim (Feb 9-12)

Interop Hackathon Results

Major live interop testing at Google’s Boulder office:

• martin-duke’s quiche-moq relay at quichemoq.dev passed alan-frindell’s conformance test: 41/41 tests passed for draft-16 WebTransport
• suhas-nandakumar: 4-5 simulcast video tracks published and received over draft-16, tested with both moxygen and quiche relay
• luke-curley: moq-dev Rust publisher to JS subscriber working through Martin’s relay
• MOQtail (Zafer Gurel): Successfully published namespace, subscribed to tracks, got objects with both moq-rs (cloudflare/moq-rs) and moxygen
• lorenzo-miniero: Testing v16 relay against other implementations
• moq-rs (cloudflare/moq-rs) draft-16 branch: 4/6 interop tests passing against Google’s draft-16 relay
• Akamai test tools: moq-test.akaleapi.net and beta version at moq-test-beta.akaleapi.net

Interop Runner Launch

Mike English announced the interop-runner reports are now live at englishm.github.io/moq-interop-runner/. Key details:

• Everyone can register in implementations.json
• VERSION-MATCHING.md documents how version matching works
• PR #34 added quiche-moq relay Docker image
• Output format change planned for better defined results

Priority Queue Performance (Feb 15)

alan-frindell shared benchmarks on priority implementation:

• Spec requires two-level priority queue (per-track + cross-track)
• Compared to single “flattened heap” approach
• Two-level is 25-60% slower depending on track structure
• Question: Does the fairness benefit justify the cost?
• For aligned tracks with similar stream counts, output is basically the same

MSF/CMSF Offsite Meeting (Feb 5)

will-law shared a group photo from a dedicated offsite meeting on MSF/CMSF formatting.

Request ID Bug (Feb 5-9)

Spec bug discovered: REQUEST_ERROR accidentally lost Request ID and Error Code fields during varint PR (#1016). SUBSCRIBE_NAMESPACE request IDs don’t follow the same increment-by-2 rule as control stream request IDs.
