 A YANG Data Model for Path Computation Element Communications Protocol
                                 (PCEP)
                      draft-ietf-pce-pcep-yang-01

Abstract

   This document defines a YANG data model for the management of Path
   Computation Element communications Protocol (PCEP) for communications
   between a Path Computation Client (PCC) and a Path Computation
   Element (PCE), or between two PCEs.  The data model includes
   configuration data and state data (status information and counters
   for the collection of statistics).
