    abstract =  {The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. The stateful PCE extensions allow stateful control of Multi-Protocol Label Switching (MPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) using PCEP. This document defines Path Computation Element Communication Protocol (PCEP) extensions for binding two reverse unidirectional RSVP-TE LSPs into an Associated Bidirectional Label Switched Path (LSP).},
