The IESG has approved the following document: - 'TRILL (TRansparent Interconnection of Lots of Links): ECN (Explicit Congestion Notification) Support' (draft-ietf-trill-ecn-support-07.txt) as Proposed Standard This document is the product of the Transparent Interconnection of Lots of Links Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-trill-ecn-support/ Technical Summary This specification provides for any Explicit Congestion Notification (ECN) marking in traffic ingressed by TRILL to be copied into the TRILL Extension Header Flags Word [RFC7179]. It also enables congestion marking by a congested transit TRILL switch in the TRILL Header Extension Flags Word. At TRILL egress, it specifies how any ECN markings in the TRILL Header Flags Word and in the encapsulated traffic are combined so that subsequent forwarding elements can see if congestion was experienced at any previous point in the path from the Source. Working Group Summary There was no particular controversy about this document. Although some minor technical refinements were made during the WG process, the WG appears to have been favorably disposed towards this work from the beginning. Document Quality No implementations of draft-ietf-trill-ecn-support-03. Document has been reviewed by RTG-DIR (QA review).
