The IESG has received a request from the Transport Area Working Group WG (tsvwg) to consider the following document: - 'Explicit Congestion Notification (ECN) Experimentation' <draft-ietf-tsvwg-ecn-experimentation-05.txt> as Proposed Standard 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 2017-09-19. 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 memo updates RFC 3168, which specifies Explicit Congestion Notification (ECN) as a replacement for packet drops as indicators of network congestion. It relaxes restrictions in RFC 3168 that would otherwise hinder experimentation towards benefits beyond just removal of loss. This memo summarizes the anticipated areas of experimentation and updates RFC 3168 to enable experimentation in these areas. An Experimental RFC is required to take advantage of any of these enabling updates. In addition, this memo makes related updates to the ECN specifications for RTP in RFC 6679 and for DCCP in RFC 4341, RFC 4342 and RFC 5622. This memo also records the conclusion of the ECN Nonce experiment in RFC 3540, and provides the rationale for reclassification of RFC 3540 as Historic; this reclassification enables new experimental use of the ECT(1) codepoint. Please note that this is a second Last Call, necessary because the first Last Call announcement omitted notification of a normative downref to RFC 3540, the document being moved to Historic. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-ecn-experimentation/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-ecn-experimentation/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references.
