PCE in Native IP Network
draft-ietf-teas-pce-native-ip-01
Abstract
This document defines the framework for CCDR traffic engineering
within Native IP network, using Dual/Multi-BGP session 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 CCDR traffic engineering is
described in draft [I-D.ietf-teas-native-ip-scenarios].

1. Introduction
Draft [I-D.ietf-teas-native-ip-scenarios] describes the scenario and
simulation results for the CCDR traffic engineering. In summary, the
requirements for CCDR traffic engineering in Native IP network are
the following:
o No complex MPLS signaling procedure.
o End to End traffic assurance, determined QoS behavior.
o Identical deployment method for intra- and inter- domain.
o No influence to existing router forward behavior.
o Can utilize 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.
