Title : A Conservative Selective Acknowledgment (SACK)-based Los= s Recovery Algorithm for TCP Author(s) : Ethan Blanton Mark Allman Lili Wang Ilpo Jarvinen Markku Kojo Yoshifumi Nishida Filename : draft-ietf-tcpm-3517bis-00.txt Pages : 14 Date : 2012-01-12 This document presents a conservative loss recovery algorithm for TCP that is based on the use of the selective acknowledgment (SACK) TCP option. The algorithm presented in this document conforms to the spirit of the current congestion control specification (RFC 5681), but allows TCP senders to recover more effectively when multiple segments are lost from a single flight of data.

I thank David for his efforts; I had the pleasure of co-chairing with him, and learned a lot about the IETF and chairing from our time together. David helped chair the group through a busy time, with a number of milestones completed and several others making positive progress. We can now prod him more about the MSS and 1323bis documents, since he won't be distracted by chairing! :) Michael Scharf will continue on as a chair, and I decided that TCPM will move to having 3 co-chairs, instead of just 2. I'm hoping this will help with the sometimes large number of documents and proposals brought to TCPM, and will also give good odds of having multiple chairs at the meetings, since we tend to make good progress in-person in TCPM. So, joining Michael, I'd like to welcome Yoshifumi Nishida and Pasi Sarolahti as new co-chairs of TCPM. Both are familiar with the working group, have chaired other groups, and I'm sure will be excellent choices for TCPM. I've requested the IESG secretary to send them "chair hats" and the IETF web pages and tools should be updated soon. -- Wes Eddy MTI Systems From touch@isi.edu Tue Jan 17 16:21:49 2012 Return-Path: X-Original-To: tcpm@ietfa.amsl.com Delivered-To: tcpm@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 9BB0B21F84F7 for ; Tue, 17 Jan 2012 16:21:49 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -104.885 X-Spam-Level: X-Spam-Status: No, score=-104.885 tagged_above=-999 required=5 tests=[AWL=1.714, BAYES_00=-2.599, RCVD_IN_DNSWL_MED=-4, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id gXQYcclV36Jo for ; Tue, 17 Jan 2012 16:21:42 -0800 (PST) Received: from boreas.isi.edu (boreas.isi.edu [128.9.160.161]) by ietfa.amsl.com (Postfix) with ESMTP id 238C921F84F1 for ; Tue, 17 Jan 2012 16:21:42 -0800 (PST) Received: from [128.9.160.252] (pen.isi.edu [128.9.160.252]) (authenticated bits=0) by boreas.isi.edu (8.13.8/8.13.8) with ESMTP id q0I0L424021610 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT); Tue, 17 Jan 2012 16:21:05 -0800 (PST) Message-ID: <4F161070.8070306@isi.edu> Date: Tue, 17 Jan 2012 16:21:04 -0800 From: Joe Touch User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20111105 Thunderbird/8.0 MIME-Version: 1.0 To: "tcpm@ietf.org" References: <20120117222654.13361.53860.idtracker@ietfa.amsl.com> In-Reply-To: <20120117222654.13361.53860.idtracker@ietfa.amsl.com> X-Forwarded-Message-Id: <20120117222654.13361.53860.idtracker@ietfa.amsl.com> Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit X-ISI-4-43-8-MailScanner: Found to be clean X-MailScanner-From: touch@isi.edu Subject: [tcpm] Fwd: New Version Notification for draft-touch-tcpm-automatic-iw-02.txt X-BeenThere: tcpm@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: TCP Maintenance and Minor Extensions Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 18 Jan 2012 00:21:49 -0000 FYI.

Filename: draft-touch-tcpm-automatic-iw Revision: 02 Title: Automating the Initial Window in TCP Creation date: 2012-01-17 WG ID: Individual Submission Number of pages: 10 Abstract: The Initial Window (IW) provides the starting point for TCP's feedback-based congestion control algorithm. Its value has increased over time to increase performance and to reflect increased capability of Internet devices. This document describes a mechanism to adjust the IW over long timescales, to make future changes more safely deployed and to potentially avoid reexamination of this value in the future.

This draft is a work item of the TCP Maintenance and Minor Extensions = Working Group of the IETF. Title : The NewReno Modification to TCP's Fast Recovery Algorithm Author(s) : Tom Henderson Sally Floyd Andrei Gurtov Yoshifumi Nishida Filename : draft-ietf-tcpm-rfc3782-bis-05.txt Pages : 15 Date : 2012-01-20 RFC 5681 documents the following four intertwined TCP congestion control algorithms: slow start, congestion avoidance, fast retransmit, and fast recovery. RFC 5681 explicitly allows certain modifications of these algorithms, including modifications that use the TCP Selective Acknowledgement (SACK) option (RFC 2883), and modifications that respond to "partial acknowledgments" (ACKs which cover new data, but not all the data outstanding when loss was detected) in the absence of SACK. This document describes a specific algorithm for responding to partial acknowledgments, referred to as NewReno. This response to partial acknowledgments was first proposed by Janey Hoe. This document obsoletes RFC 3782.

Title : A Conservative Selective Acknowledgment (SACK)-based Los= s Recovery Algorithm for TCP Author(s) : Ethan Blanton Mark Allman Lili Wang Ilpo Jarvinen Markku Kojo Yoshifumi Nishida Filename : draft-ietf-tcpm-3517bis-01.txt Pages : 14 Date : 2012-01-26 This document presents a conservative loss recovery algorithm for TCP that is based on the use of the selective acknowledgment (SACK) TCP option. The algorithm presented in this document conforms to the spirit of the current congestion control specification (RFC 5681), but allows TCP senders to recover more effectively when multiple segments are lost from a single flight of data.
