Name: Congestion Control Working Group (CCRG)
RFC 5033 describes a Best Current Practice to evaluate new congestion control algorithms as Experimental or Proposed Standard RFCs. TCP was the dominant consumer of this work, and proposals were typically discussed in research groups, for example the Internet Congestion Control Research Group (ICCRG).
Since RFC 5033 was published, many conditions have changed. Congestion control algorithm proponents now often have the opportunity to test and deploy at scale without IETF review. The set of protocols using these algorithms has spread beyond TCP and SCTP to include DCCP, QUIC, and beyond. There is more interest in specialized use cases such as data centers and real-time protocols. Finally, the community has gained much more experience with indications of congestion beyond packet loss.
The Congestion Control Working Group will review some of the impediments to congestion control work occurring in the IETF and can generalize transports from TCP to all of the relevant transport protocols. This will inform a revision of RFC 5033 that encourages IETF review of congestion control proposals and standardization of mature congestion control algorithms.
The congestion control expertise in the working group also makes it a natural venue to take on other work related to indications of congestion such as delay, queuing algorithms, rate pacing, multipath, interaction with other layers, among others. In particular, it can address congestion control algorithms with empirical evidence of safety and stated intent to deploy by major implementations. The working group is intended to be a home for such work, and it is chartered to adopt proposals in this space if such congestion control algorithms are presented before or after the completion of the primary deliverable i.e. 5033bis.
Formation of this working group was and has been discussed in tsvarea, tsvwg and congress mailing list.

The working group chartering is in motion and likely to be chartered by IETF117. This is a placeholder so that we can schedule it.
