Multiprotocol Label Switching Traffic Engineered (MPLS TE) Label
Switched Paths (LSPs) may be established wholly within an Autonomous
System (AS) or may cross AS boundaries.

The Path Computation Element (PCE) is a component that is capable of
computing constrained paths for (G)MPLS TE LSPs.  The PCE Communication Protocol (PCECP) is defined to allow communication between Path Computation Clients (PCCs) and PCEs, as well as between PCEs.
The PCECP is used to request constrained paths and to supply computed
paths in response.  Generic requirements for the PCECP are set out in
"Path Computation Element (PCE) Communication Protocol Generic
Requirements", RFC 4657.  This document extends those requirements to
cover the use of PCECP in support of inter-AS MPLS TE.  This memo provides 
information for the Internet community.

This document is a product of the Path Computation Element Working Group of the IETF.
