The IESG has approved the following document: - 'Applicability of the Path Computation Element (PCE) to Point-to-Multipoint (P2MP) Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering (TE) ' <draft-ietf-pce-p2mp-app-02.txt> as an Informational RFC This document is the product of the Path Computation Element Working Group. The IESG contact persons are Ross Callon and Adrian Farrel. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-pce-p2mp-app-02.txt Technical Summary The Path Computation Element (PCE) provides path computation functions in support of traffic engineering in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. Extensions to the MPLS and GMPLS signaling and routing protocols have been made in support of point-to-multipoint (P2MP) Traffic Engineered (TE) Label Switched Paths (LSPs). This informational document examines the applicability of PCE to path computation for P2MP TE LSPs in MPLS and GMPLS networks. It describes the motivation for using a PCE to compute these paths, and examines which of the PCE architectural models are appropriate. Working Group Summary The I-D has had some level of discussions and review in the PCE working group, and has gone through IETF last call. No controversy reported (see PROTO writeup by JP Vasseur). Document Quality This informational document does not define any protocol that could be implemented. Rather, there are other documents currently being progressed in the PCE WG that define the associated requirements and protocol extensions. Multiple service providers have expressed a requirement for these extensions, and reportedly there is at least one implementation in testing. Personnel JP Vasseur is the Document Shepherd for this document. Ross Callon is the Responsible Area Director. The document has no IANA implications. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
