PCE in Native IP Network
draft-ietf-teas-pce-native-ip-03
Abstract
This document defines the framework for traffic engineering within
native IP network, using Dual/Multi-BGP sessions strategy and PCE-
based central control architecture. The proposed central mode
control framework conforms to the concept that defined in [RFC8283].
The scenario and simulation results of traffic engineering in Native
IP network is described in draft [I-D.ietf-teas-native-ip-scenarios].

1. Introduction
Draft [I-D.ietf-teas-native-ip-scenarios] describes the scenarios,
simulation results and suggestions for traffic engineering in native
IP network. To meet the requirements of various scenarios, the
solution for traffic engineering in native IP network should have the
followings criteria:
o No complex MPLS signaling procedures.
o End to End traffic assurance, determined QoS behavior.
o Identical deployment method for intra-domain and inter-domain.
o No influence to forwarding behavior of the router.
o Can exploit the power of centrally control (PCE) and flexibility/
robustness of distributed control protocol.
o Coping with the differentiation requirements for large amount
traffic and prefixes.
