The IESG has approved the following document: - 'Problem Statement and Requirements for a More Accurate ECN Feedback' (draft-ietf-tcpm-accecn-reqs-08.txt) as Informational RFC This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Spencer Dawkins and Martin Stiemerling. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tcpm-accecn-reqs/ Technical Summary Traditionally the explicit congestion notification can deliver only one congestion signal in a round-trip time with TCP. This Informational document motivates the case for delivering more accurate congestion information for TCP. It discusses high-level requirements for methods for delivering more accurate congestion information, but does not specify such mechanism. Therefore Informational is considered appropriate document type. Working Group Summary The document was reviewed by a few WG participants in its different phases, also during the WGLC. There has been no controversy over it. TCPM chairs believe the document is stable and has gone through a sufficient review, and is ready for publication. Document Quality There are no implementations, as this is solely a requirements document. The reviews done ins mentioned under WG summary. Personnel The document shepherd is Pasi Sarolahti. The responsible AD is Martin Stiemerling.
