The IESG has received a request from the Congestion Exposure WG (conex) to consider the following document: - 'ConEx Concepts and Use Cases' <draft-ietf-conex-concepts-uses-04.txt> as an Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-04-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document provides the entry point to the set of documentation about the Congestion Exposure (ConEx) protocol. It explains the motivation for including a ConEx marking at the IP layer: to expose information about congestion to network nodes. Although such information may have a number of uses, this document focuses on how the information communicated by the ConEx marking can serve as the basis for significantly more efficient and effective traffic management than what exists on the Internet today. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-conex-concepts-uses/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-conex-concepts-uses/ballot/ No IPR declarations have been submitted directly on this I-D.
