Mohamed, As requested, I am fwd'ing the new version announcement to the sfc list. The only delta was to use your words to describe the SFC architecture (with slight changes). Bob -------- Forwarded Message -------- Subject: [tsvwg] I-D Action: draft-ietf-tsvwg-rfc6040update-shim-04.txt Date: Mon, 03 Jul 2017 16:43:11 -0700 From: internet-drafts@ietf.org To: i-d-announce@ietf.org CC: tsvwg@ietf.org A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transport Area Working Group of the IETF. Title : Propagating Explicit Congestion Notification Across IP Tunnel Headers Separated by a Shim Author : Bob Briscoe Filename : draft-ietf-tsvwg-rfc6040update-shim-04.txt Pages : 16 Date : 2017-07-03 Abstract: RFC 6040 on "Tunnelling of Explicit Congestion Notification" made the rules for propagation of ECN consistent for all forms of IP in IP tunnel. This specification updates RFC 6040 to clarify that its scope includes tunnels where two IP headers are separated by at least one shim header that is not sufficient on its own for wide area packet forwarding. It surveys widely deployed IP tunnelling protocols separated by such shim header(s) and updates the specifications of those that do not mention ECN propagation (L2TPv2, L2TPv3, GRE and Teredo). This specification also updates RFC 6040 with configuration requirements needed to make any legacy tunnel ingress safe. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-rfc6040update-shim/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-tsvwg-rfc6040update-shim-04 https://datatracker.ietf.org/doc/html/draft-ietf-tsvwg-rfc6040update-shim-04 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-tsvwg-rfc6040update-shim-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
