I thought this was originally proposed as an Experimental RFC - the minutes from the tsvwg DC meeting confirm that. When, how and why was this changed?

The chairs/ADs deemed it a sufficiently minor (yet useful) change to SACK that it doesn't seem necessary to go the route of first publishing it as Experimental. When the TSVWG working group last call was issued, it was for publishing the document as Proposed, and we noted: > The document was discussed > at the last IETF and appears to have good support and no controversial > issues. There were no working group last call comments.

This draft is a work item of the Transport Area Working Group Working Group of the IETF. Title : TCP Congestion Window Validation Author(s) : M. Handley, J. Padhye, S. Floyd Filename : draft-handley-tcp-cwv-02.txt Pages : 11 Date : 14-Mar-00 TCP's congestion window controls the number of packets a TCP flow may have in the network at any time. However, long periods when the sender is idle or application-limited can lead to the invalidation of the congestion window, in that the congestion window no longer reflects current information about the state of the network. This document describes a simple modification to TCP's congestion control algorithms to decay the congestion window cwnd after the transition from a sufficiently-long application-limited period, while using the slow-start threshold ssthresh to save information about the previous value of the congestion window. An invalid congestion window also results when the congestion window is increased (i.e., in TCP's slow-start or congestion avoidance phases) during application-limited periods, when the previous value of the congestion window might never have been fully utilized. We propose that the TCP sender should not increase the congestion window when the TCP sender has been application-limited (and therefore has not fully used the current congestion window). We have explored these algorithms both with simulations and with experiments from an implementation in FreeBSD.

NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <20000314133246.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-handley-tcp-cwv-02.txt --OtherAccess Content-Type: Message/External-body; name="draft-handley-tcp-cwv-02.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <20000314133246.I-D@ietf.org> --OtherAccess-- --NextPart-- _______________________________________________ tsvwg mailing list tsvwg@ietf.org http://www.ietf.org/mailman/listinfo/tsvwg
