Control messages
What each request got back, per draft. ok and err are both answers; ✗ is a request refused or left unanswered; a dash is a request our side did not complete. Times run from the request to its answer; each request waited up to 3,000 ms.

Media delivery
One publisher and two subscribers, to see whether an object published through this endpoint reaches a client that asked for it.
The subscription routed to the publisher could not be read. The connection failed with no error code.
Two publishers of one track
Two publishers announce the same namespace and publish the same tracks, one with identical payloads and one with payloads that differ by publisher. Partway through, the publisher serving the subscribers disconnects without notice. A fresh subscription, sent afterwards, shows whether the remaining publisher could still be reached.
| Publisher | Role | Announcement | Subscribed to | Ended by the relay |
|---|---|---|---|---|
| first publisher | standby The relay accepted it and never subscribed to it while a subscriber was waiting. | accepted, REQUEST_OK in 30 ms | — | — |
| second publisher disconnected | serving The relay accepted it and subscribed to it. | accepted, REQUEST_OK in 29 ms | differing payloads, identical payloads | — |
| Track | Objects | From | When the publisher left | Ended by |
|---|---|---|---|---|
| identical payloads | each object once 15 delivered | — | ended by the relay | PUBLISH_DONE 0 “internal error” |
| differing payloads | each object once 15 delivered | second publisher | ended by the relay | PUBLISH_DONE 0 “internal error” |
A fresh subscription after the publisher left: delivered, the relay subscribed to the first publisher, first object in 64 ms.
Ended or stalled a subscription when its publisher left, while the other publisher of the track was still accepted and reachable.
Draft 22, on the track with identical payloads
- Requirement
- A relay must forward Objects of one track from every publisher of it to the matching subscriptions.
- Specification
- draft-ietf-moq-transport-22, Section 7.3

Setup parameters
What this endpoint sent back in its setup response, per draft. A parameter with no name is a code point the negotiated draft does not define.

The relay names itself moq-lite-rs under option 0x07, which is MOQT_IMPLEMENTATION from draft-15 onward. Draft-14 assigns nothing to 0x07, so a draft-14 client has no reason to read it as a name.

If something here is wrong, tell us — we keep what each result rests on, so a disputed one gets re-read rather than re-argued. We can also run this against endpoints that are not public.
