A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Preventing SCTP Congestion Window Overgrowth During Changeover Author(s) : J. Iyengar Filename : draft-iyengar-sctp-cacc-02.txt Pages : 9 Date : 2004-2-13 SCTP [RFC2960] supports IP multihoming at the transport layer. SCTP allows an association to span multiple local and peer IP addresses, and allows the application to dynamically change the primary destination during an active association. We present a problem in the current SCTP specification that results in unnecessary retransmissions and 'TCP-unfriendly' growth of the sender's congestion window during certain changeover conditions. We present the problem and propose an algorithm called the Split Fast Retransmit Changeover Aware Congestion Control (SFR-CACC) algorithm as a solution. We recommend the addition of the SFR-CACC algorithm to the SCTP specification [RFC2960].

Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-iyengar-sctp-cacc-02.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-iyengar-sctp-cacc-02.txt". 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.
