A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transport Area Working Group Working Group of the IETF. Title : Robust ECN Signaling with Nonces Author(s) : D. Wetherall et al. Filename : draft-ietf-tsvwg-tcp-nonce-01.txt Pages : 11 Date : 19-Jul-01 This note describes the ECN-nonce, a modification to ECN that protects against accidental or malicious concealment of marked packets from the TCP sender. It improves the robustness of congestion control by preventing receivers from exploiting ECN to gain an unfair share of network bandwidth. The ECN-nonce uses the two ECT codepoints in the ECN field of the IP header, and requires a new flag in the TCP header. It is computationally efficient for both routers and hosts. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-tsvwg-tcp-nonce-01.txt 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-ietf-tsvwg-tcp-nonce-01.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-ietf-tsvwg-tcp-nonce-01.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.
