Folks, Thanks to some folks' push over time, and the fact that both co-authors happened to find themselves at IETF 92, we've reposted our latests version of this I-D (since the previous one had expired), in the hopes of making progress. Any comments on this rev will be appreciated. Additionally, I'll repost/fwd Karen's latest comments on this I-D, which will be the basis for the changes in the next rev. Thanks! Best regards, Fernando -------- Forwarded Message -------- Subject: New Version Notification for draft-gont-tcpm-tcp-seq-validation-02.txt Date: Thu, 26 Mar 2015 11:55:46 -0700 From: internet-drafts@ietf.org To: Fernando Gont <fgont@si6networks.com>, David Borman <david.borman@quantum.com>, Fernando Gont <fgont@si6networks.com>, David Borman <david.borman@quantum.com> A new version of I-D, draft-gont-tcpm-tcp-seq-validation-02.txt has been successfully submitted by Fernando Gont and posted to the IETF repository. Name: draft-gont-tcpm-tcp-seq-validation Revision: 02 Title: On the Validation of TCP Sequence Numbers Document date: 2015-03-26 Group: Individual Submission Pages: 16 URL: http://www.ietf.org/internet-drafts/draft-gont-tcpm-tcp-seq-validation-02.txt Status: https://datatracker.ietf.org/doc/draft-gont-tcpm-tcp-seq-validation/ Htmlized: http://tools.ietf.org/html/draft-gont-tcpm-tcp-seq-validation-02 Diff: http://www.ietf.org/rfcdiff?url2=draft-gont-tcpm-tcp-seq-validation-02 Abstract: When TCP receives packets that lie outside of the receive window, the corresponding packets are dropped and either an ACK, RST or no response is generated due to the out-of-window packet, with no further processing of the packet. Most of the time, this works just fine and TCP remains stable, especially when a TCP connection has unidirectional data flow. However, there are three scenarios in which packets that are outside of the receive window should still have their ACK field processed, or else a packet war will take place. The aforementioned issues have affected a number of popular TCP implementations, typically leading to connection failures, system crashes, or other undesirable behaviors. This document describes the three scenarios in which the aforementioned issues might arise, and formally updates RFC 793 such that these potential problems are mitigated. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
