The Path Computation Element (PCE) provides path computation
functions in support of traffic engineering in Multiprotocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) networks.
MPLS and GMPLS networks may be constructed from layered service
networks. It is advantageous for overall network efficiency to
provide end-to-end traffic engineering across multiple network
layers through a process called inter-layer traffic engineering.
PCE is a candidate solution for such requirements.
The PCE communication Protocol (PCEP) is designed as a
communication protocol between Path Computation Clients (PCCs) and
PCEs. This document presents PCEP extensions for inter-layer
traffic engineering.
