The Path Computation Element (PCE) provides functions of path
computation in support of traffic engineering in networks controlled by
Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS).
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, "Path
Computation Element (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.
