Internet-Draft PCEP Extension for Native IP Network June 26, 2018
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 [draft-ietf-teas-native-ip-scenarios] and [draft-
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 [draft-
ietf-teas-pce-control-function] to correlate the forwarding behavior
among different network devices. Draft [draft-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.
