The Path Computation Element (PCE) provides path computation
functions 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 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.
