Subject: Document Action: 'Applicability of the Path Computation Element (PCE) to Point-to-Multipoint (P2MP) Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering (TE)' to Informational RFC
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:
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).
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.
JP Vasseur is the Document Shepherd for this document. Ross Callon
is the Responsible Area Director. The document has no IANA
