                  PCEP Extension for Native IP Network
               draft-ietf-pce-pcep-extension-native-ip-09

Abstract

   This document defines the Path Computation Element Communication
   Protocol (PCEP) extension for Central Control Dynamic Routing (CCDR)
   based application in Native IP network.  The scenario and framework
   of CCDR in native IP is described in [RFC8735] and
   [I-D.ietf-teas-pce-native-ip].  This draft describes the key
   information that is transferred between Path Computation Element
   (PCE) and Path Computation Clients (PCC) to accomplish the End to End
   (E2E) traffic assurance in Native IP network under central control
   mode.
