The IESG has approved the following document: - 'TCP Extensions for High Performance' (draft-ietf-tcpm-1323bis-21.txt) as Proposed Standard This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Martin Stiemerling and Spencer Dawkins. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tcpm-1323bis/ Technical Summary This document replaces RFC 1323, making minor fixes and clarifications to the original document. The document specifies three performance enhancing extensions to TCP, using two TCP options. The first is window scale option, that allows representation of receive window sizes larger than 2^16 bytes originally allowed by the 16-bit window field. The second option is TCP timestamps option that allows round-trip time measurement on each TCP segment, and third is an algorithm to detect and reject old duplicate segments that happen to match the current TCP window (Protect Against Wrapped Sequence numbers). Working Group Summary This document has been a chartered TCPM working group item since year 2008. It has not been under significant controversy, but the progress has been slow because of earlier lack of WG (and authoring) cycles. Since adding a new co-editor, the progress on the draft became faster in the working group. Document Quality The predecessor of this document, RFC 1323, was published in 1992, and is deployed in most TCP implementations. This document includes fixes and clarifications based on the gained deployment experience. The recent versions of the document have been reviewed and discussed by multiple working group participants. Personnel Document Shepherd is Pasi Sarolahti. Reponsible Area Director is Martin Stiemerling.
