Title : PCC-PCE Communication and PCE Discovery Requirements for Inter-Layer Traffic Engineering
Author(s) : E. Oki, et al.
Filename : draft-ietf-pce-inter-layer-req-15.txt

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) controlled networks.
MPLS and GMPLS networks may be constructed from layered client/server
networks. It is advantageous for overall network efficiency to
provide end-to-end traffic engineering across multiple network
layers. PCE is a candidate solution for such requirements.
Generic requirements for a communication protocol between Path
Computation Clients (PCCs) and PCEs are presented in RFC 4657, "PCE
Communication Protocol Generic Requirements". Generic requirements
for a PCE discovery protocol are presented in RFC 4674, "Requirements
for Path Computation Element (PCE) Discovery".
This document complements the generic requirements and presents
detailed sets of PCC-PCE communication protocol requirements and PCE
discovery protocol requirements for inter-layer traffic engineering.
