The IESG has approved the following document: - 'Extensions to the Path Computation Element Communication Protocol (PCEP) for Route Exclusions ' <draft-ietf-pce-pcep-xro-06.txt> as a Proposed Standard This document is the product of the Path Computation Element Working Group. The IESG contact persons are Ross Callon and David Ward. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-pce-pcep-xro-06.txt Technical Summary The PCE Communication Protocol (PCEP) is designed as a communication protocol between PCCs and PCEs. This document presents PCEP extensions for route exclusions. The Path Computation Element (PCE) provides functions of path computation in support of traffic engineering in Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. When a Path Computation Client (PCC) requests a PCE for a route, it may be useful for the PCC to specify, as constraints to the path computation, abstract nodes, resources, and Shared Risk Link Groups (SRLGs) that are to be explicitly excluded from the computed route. Such constraints are termed route exclusions. Working Group Summary The document has been discussed and reviewed by several key WG members. Good consensus reported within the WG. No review by non WG members that has been considered necessary. The solution specified in this document has a good support in the WG, and satisfies a well specified requirement for the PCEP protocol (RFC4657). Document Quality There is one known implementation of this document with several other unknown implementations. An interoperability event (ISOCRE) with multiple implementations is planned. Personnel JP Vasseur is the document shepherd. Ross Callon is the responsible AD. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
