               draft-ietf-pce-pcep-extension-native-ip-01

Abstract

   This document defines the PCEP extension for CCDR application in
   Native IP network.  The scenario and architecture of CCDR in native
   IP is described in [I-D.ietf-teas-native-ip-scenarios] and
   [I-D.ietf-teas-pce-native-ip].  This draft describes the key
   information that is transferred between PCE and PCC to accomplish the
   end2end traffic assurance in Native IP network under central control
   mode.

1.  Introduction

   Traditionally, MPLS-TE traffic assurance requires the corresponding
   network devices support MPLS or the complex RSVP/LDP/Segment Routing
   etc. technologies to assure the end-to-end traffic performance.  But
   in native IP network, there will be no such signaling protocol to
   synchronize the action among different network devices.  It is
   necessary to use the central control mode that described in [RFC8283]
   to correlate the forwarding behavior among different network devices.
   Draft [I-D.ietf-teas-pce-native-ip] describes the architecture and
   solution philosophy for the end2end traffic assurance in Native IP
   network via Dual/Multi BGP solution.  This draft describes the
   corresponding PCEP extension to transfer the key information about
   peer address list, peer prefix association and the explicit peer
   route on on-path router.
