The IESG has approved the following document: - 'Guidelines for Adding Congestion Notification to Protocols that Encapsulate IP' (draft-ietf-tsvwg-ecn-encap-guidelines-22.txt) as Best Current Practice This document is the product of the Transport and Services Working Group. The IESG contact persons are Zaheduzzaman Sarker and Martin Duke. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-ecn-encap-guidelines/ Technical Summary 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. Working Group Summary Sebastian Moeller repeatedly questioned on the mailing list the use of recommendations that were based on an earlier BCP, i.e. RFC 7141, saying that some of the earlier concepts recommended in RFC 7141 were yet to be implemented. The chairs and editors are content that the current revision has considered this feedback and looked into these topics, and that citing RFC 7141 is consistent with good practice. Document Quality This is a BCP that is not directly implementable, but 4 RFCs and 3 I-Ds reference it. Personnel The Document Shepherd for this document is Gorry Fairhurst. The Responsible Area Director is Martin Duke.
