PCEP Extension for Native IP Network
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.
