On the Implementation of the TCP Urgent Mechanism
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org>, tcpm mailing list <email@example.com>, tcpm chair <firstname.lastname@example.org> Subject: Protocol Action: 'On the implementation of the TCP urgent mechanism' to Proposed Standard The IESG has approved the following document: - 'On the implementation of the TCP urgent mechanism ' <draft-ietf-tcpm-urgent-data-07.txt> as a Proposed Standard This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact person is Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-tcpm-urgent-data-07.txt
Technical Summary This document analyzes how current TCP implementations process TCP urgent indications, and how the behavior of some widely-deployed middle-boxes affect how urgent indications are processed by end systems. This document updates the relevant specifications such that they accommodate current practice in processing TCP urgent indications, provides advice to applications that make use of the urgent mechanism, and raises awareness about the reliability of TCP urgent indications in the current Internet. Working Group Summary Nothing exceptional occurred during the working group process for this document. Document Quality This document specifically is aimed at bringing the specification and existing implementations into line clearly with each other. The implementation practices in this document have been adopted in multiple implementations and this document provides guidance to aid in future compatibility with applications in new and old TCP implementations. Personnel Wesley Eddy (Wesley.M.Eddy@nasa.gov) is the document shepherd. Lars Eggert (email@example.com) reviewed this document for the IESG.
