Abstract

The Path Computation Element (PCE) provides path computationfunctions in support of traffic engineering in Multiprotocol LabelSwitching (MPLS) and Generalized MPLS (GMPLS) networks.

MPLS and GMPLS networks may be constructed from layered servicenetworks. It is advantageous for overall network efficiency toprovide end-to-end traffic engineering across multiple network layersthrough a process called inter-layer traffic engineering. PCE is acandidate solution for such requirements.

The PCE Communication Protocol (PCEP) is designed as a communicationprotocol between Path Computation Clients (PCCs) and PCEs. Thisdocument presents PCEP extensions for inter-layer trafficengineering.
