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.
