Performance and Congestion Control (pcc) Charter Status: Concluded January, 1991 Chair(s): Allison Mankin Description of Working Group: The IETF Performance and Congestion Control Working Group is chartered to collect and develop short-term techniques for improving Internet performance, methods like TCP Slow-start, which are retrofittable and inexpensive to implement. After a preliminary draft of a white paper documenting such performance enhancements for hosts and gateways, it was decided to sharpen the focus and divide the material into two papers. The first paper is the Internet-Draft on gateway congestion control policies and algorithms. The intent of this paper is to present what is now known about the difficult problem of avoiding congestion in Internet gateways. It describes proposed policies such as Random Drop, Congestion Indication, and Fair Queuing, and sketches ground-rules for their adoption. An additional goal of the paper (achieved during the writing) is to generate dialogue on longer-term Internet gateway performance problems. The other paper is an RFC on TCP performance. This describes TCP algorithms such as Retransmit Backoff, Slow-start, Nagle (Small-Packet Avoidance), and Delayed Ack, as well as their correct interaction. The scope is to expand the treatment of TCP performance found in the Host Requirements RFC. Request for Comments:
