The IESG has approved the Internet-Draft 'TCP Congestion Control' <draft-ietf-tcpimpl-cong-control-05.txt> as a Proposed Standard. This document obsoletes RFC 2001. The IESG also approved The NewReno Modification to TCP's Fast Recovery Algorithm <draft-ietf-tcpimpl-newreno-02.txt> as an Experimental RFC. These documents are the product of the TCP Implementation Working Group. The IESG contact persons are Scott Bradner and Vern Paxson. Technical Summary The TCP Congestion Control document specifies four TCP congestion control algorithms: slow start, congestion avoidance, fast retransmit and fast recovery. The document is an update of RFC 2001. In addition to specifying the congestion control algorithms, it specifies what TCP connections should do after a relatively long idle period, as well as specifying and clarifying some of the issues pertaining to TCP ACK generation. The NewReno Modification document describes a specific algorithm for responding to partial acknowledgments, referred to as NewReno. This document is published as an Experimental RFC to elicit implementation and testing experience. Working Group Summary There was significant discussion about early versions of these documents but all issues were resolved in the final versions. Protocol Quality These documents were reviewed for the IESG by Scott Bradner
