The IESG has approved the following document: - 'Requirements for Signaling of (Pre-) Congestion Information in a DiffServ Domain' (draft-ietf-pcn-signaling-requirements-08.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-signaling-requirements/ Technical Summary PCN (RFC 5559) conveys pre-congestion information to an egress router via in-band packet marking. This document defines the requirements for signaling protocols that convey PCN feedback information from a PCN egress router to a PCN decision point, and between the decision point and a PCN ingress router (if they are not co-located). The signaling requirements apply specifically to the Single Marking [RFCXXXX] and Controlled Load PCN [RFCXXXX] edge behaviours. Working Group Summary The document was subject to thorough review by the PCN working group, and strong consensus for publication was reached. Document Quality As an Informational document, there are no implementations, but two companion documents are consistent with these signaling requirements. The document shepherd expects that there are additional requirements (e.g., congestion control) that are generic to any Internet protocol, that are not explicitly captured in this draft, but expects that as the working group begins to define (or adapt) one or more signaling protocols, that these requirements will be taken into account. There are references to draft-ietf-pcn-cl-edge-behaviour (Controlled Load) and draft-pcn-sm-edge-behaviour (Single Marking), which have also been submitted for publication.
