Hello colleagues at QUIC WG. I'm Yuan Jinghao from ByteDance, and I'd like to introduce to you a draft we recently submitted.
We have noticed that in various scenarios, there is a demand to represent and consume congestion control status. Based on this, we have constructed a custom QUIC frame, which is composed of multiple Network Statistics. Every "Network Statistics" records network signals such as bandwidth, packet loss, and RTT, etc. This extension allows peers to exchange their cc status and enables the original data to be echoed back to the source in a secure form. We have applied the prototype of this draft in live streaming for several years and achieved actual QoE benefits. We hope that this extension can not only be applied in TikTok live but also receive professional evaluations and guidance from the industry. Thanks, Jinghao Yuan draft-00: https://datatracker.ietf.org/doc/draft-yuan-quic-congestion-data/
