The IESG has approved the following document: - 'Overview of Pre-Congestion Notification Encoding' (draft-ietf-pcn-encoding-comparison-09.txt) as an Informational RFC This document is the product of the Congestion and Pre-Congestion Notification Working Group. The IESG contact persons are David Harrington and Wesley Eddy. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pcn-encoding-comparison/ Technical Summary The PCN mechanism in routers in the interior of a PCN domain marks packets when certain configured rates are exceeded. The PCN working group explored a number of approaches for encoding this pre-congestion information into the IP header. This document describes the various approaches that were examined and discusses the constraints that had to be satisfied by a viable encoding mechanism. Working Group Summary The document was subject to thorough review by the PCN working group, and strong consensus for publication was reached. Document Quality The document was subject to thorough review by the PCN working group, and strong consensus for publication was reached. There are a number of companion documents that detail the specific approaches. Personnel Document Shepherd: Steven Blake Responsible Area Director: David Harrington RFC Editor Note 4.5 says RFC5696 was published as a draft Internet Standard. This is confusing, given the existence of the "Draft Internet Standard" status. RFC5696 is a Proposed Standard. Please reword to: "The baseline encoding described in section 4.1 is defined in [RFC5696]."
