[Moq] QUICR - Slides, Code and Drafts

[Suhas Nandakumar <[e-mail]>]

Thanks everyone for an amazing BoF and discussions.


Following up on my earlier email on QUCR, here are the slides that I was
planning to present during the MOQ BOF but couldn't present due to audio
issues

The slides introduce what usecase trends drove QUICR

thinking and how it addresses supporting secure, low latency, interactive
and efficiently scalable media delivery protocol across streaming and
interactive usecases.


Updated drafts can be found here:


QuicR Arch :

QuicR protocol:
https://www.ietf.org/archive/id/draft-jennings-moq-quicr-proto-01.html


Here are the links to open-source repos that implement the current version of
the drafts

https://github.com/Quicr/quicrq  - Implements QUICR protocol and Relay
functions over picoquic QUIC Stack

https://github.com/Quicr/libquicr  - C++ wrapper over quicrq and pub/sub
api interface for sending and consuming media


https://github.com/Quicr/qmedia - A test media library (with jitter,
encode/decode) and a sample OSX client


I have put a sample recording of a demo video that shows 1:many
distribution of real time capture between 1 publisher and 3
subscribers. Publisher
is sending Opus Audio at 48Khz and 720p H264 video with the QUICR relay
being deployed in Ohio AWS cluster

>From some early instrumentations, we have seen promising results in
latencies that are comparable to interactive media.


Also to note, these are very early drafts/work and in progress and we want
to make a bunch of changes to make this all line up better with the
direction WG is going.


Please let us know if you have any questions and as always we welcome
feedback


Cheers
