The IESG has approved the following document: - 'Diffserv-Interconnection classes and practice' (draft-ietf-tsvwg-diffserv-intercon-14.txt) as Informational RFC This document is the product of the Transport Area Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-diffserv-intercon/ Technical Summary This document defines a limited common set of Diffserv PHBs and codepoints (DSCPs) to be applied at (inter)connections of two separately administered and operated networks, and explains how this approach can simplify network configuration and operation. Many network providers operate MPLS using Treatment Aggregates for traffic marked with different Diffserv PHBs, and use MPLS for interconnection with other networks. This document offers a simple interconnection approach that may simplify operation of Diffserv for network interconnection among providers that use MPLS and apply the Short- Pipe tunnel mode. Working Group Summary The document has received significant feedback from the WG. There is strong consensus on the discussed DSCPs. Document Quality This document proceeded in parallel with related ITU-T specification (Y.1566). Personnel Who is the Document Shepherd? Gorry Fairhurst Who is the Responsible Area Director?
