Title : Inter-AS Requirements for the Path Computation Element Communication Protocol (PCECP)
Author(s) : N. Bitar
Filename : draft-ietf-pce-interas-pcecp-reqs-04.txt
Pages : 13

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 paths for MPLS-TE LSPs. The PCE Communication
Protocol(PCECP) is defined to allow communication between Path
Computation Clients (PCCs) and PCEs, and between PCEs. The PCECP is
used to request 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.
