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.
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 "PCE
Communication Protocol Generic Requirements". Generic requirements
for PCE discovery protocol are presented in "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.
