Hi all,

The Congestion Control Working Group (CCWG) focuses on specifying congestion control algorithms. Congestion control is the process a network sender uses to determine the rate at which to send data, which can help improve application performance, such as latency under load, while safeguarding overall network performance for all senders.

CCWG has sent rfc5033bis: Specifying New Congestion Control Algorithms [0] to the IESG for publication.

We’ve recently adopted our first major congestion control algorithm: BBR (“Bottleneck Bandwidth and Round-trip propagation time”). Reviews, suggestions, and feedback are most welcome, either on the mailing list [1] or as issues on the GitHub Repository [2].

We’re also looking at adopting some additional documents in the congestion control space that provide congestion controller independent improvements, which we’ll discuss at IETF 121.

We’ll have a table at the hackathon [3] for testing and building infrastructure to make congestion control development easier, come join us!

Thanks,
Reese and Eric
