PCE in Native IP Network
draft-ietf-teas-pce-native-ip-04
Abstract
This document defines the framework for traffic engineering within
native IP network, using Dual/Multi-Border Gateway Protocol (BGP)
sessions strategy and Path Computation Engine (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 and
simulation results 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 Multiprotocol Label Switching (MPLS) signaling
procedures.
o End to End traffic assurance, determined Quality of Service (QoS)
behavior.
o Same deployment method for intra-domain and inter-domain.
o No influence to forwarding behavior of the router.
