The IESG has received a request from the Transport and Services Working Group WG (tsvwg) to consider the following document: - 'Guidelines for Adding Congestion Notification to Protocols that Encapsulate IP' <draft-ietf-tsvwg-ecn-encap-guidelines-20.txt> as Best Current Practice 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 last-call@ietf.org mailing lists by 2023-11-02. 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 The purpose of this document is to guide the design of congestion notification in any lower layer or tunnelling protocol that encapsulates IP. The aim is for explicit congestion signals to propagate consistently from lower layer protocols into IP. Then the IP internetwork layer can act as a portability layer to carry congestion notification from non-IP-aware congested nodes up to the transport layer (L4). Following these guidelines should assure interworking among IP layer and lower layer congestion notification mechanisms, whether specified by the IETF or other standards bodies. This document is included in BCP 89 and updates the advice to subnetwork designers about ECN in RFC 3819. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-ecn-encap-guidelines/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc5129: Explicit Congestion Marking in MPLS (Proposed Standard - Internet Engineering Task Force (IETF)) rfc6040: Tunnelling of Explicit Congestion Notification (Proposed Standard - Internet Engineering Task Force (IETF)) draft-ietf-trill-ecn-support: TRILL (TRansparent Interconnection of Lots of Links): ECN (Explicit Congestion Notification) Support (None - Internet Engineering Task Force (IETF))
