The IESG has received a request from the Congestion and Pre-Congestion Notification WG (pcn) to consider the following document: - 'Requirements for Signaling of (Pre-) Congestion Information in a DiffServ Domain' <draft-ietf-pcn-signaling-requirements-07.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 2012-01-06. 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 Precongestion notification (PCN) is a means for protecting quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo describes the requirements for the signaling applied within the PCN domain: (1) PCN-feedback-information is carried from the PCN-egress- node to the decision point;(2) the decision point may ask the PCN- ingress-node to measure, and report back, the rate of sent PCN- traffic between that PCN-ingress-node and PCN-egress-node. The decision point may be either collocated with the PCN-ingress-node or a centralized node (in the latter case, (2) is not required). The signaling requirements pertain in particular to two edge behaviours, "controlled load (CL)" and "single marking (SM)" [draft-ietf-pcn-cl-edge- behaviour-09], [draft-ietf-pcn-sm-edge-behaviour-06].
