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.

Internet-Draft        PCE in Native IP Network        February 13, 2018
    The proposed central mode control framework conforms to the concept
    that defined in RFC " An Architecture for Use of PCE and the PCE
    Communication Protocol (PCEP) in a Network with Central Control".

    The scenario and simulation results of CCDR traffic engineering is
    described in draft "CCDR Scenario, Simulation and Suggestion".

1. Introduction

   Draft [I-D.draft-wang-teas-ccdr] 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 followings.
   1) No complex MPLS signaling procedure.
   2) End to End traffic assurance, determined QoS behavior.
   3) Identical deployment method for intra- and inter- domain.
   4) No influence to existing router forward behavior.
   5) Can utilize the power of centrally control(PCE) and
      flexibility/robustness of distributed control protocol.
   6) Coping with the differentiation requirements for large amount
      traffic and prefixes.
   7) Flexible deployment and automation control.

   This document defines the framework for CCDR traffic engineering
   within Native IP network, using Dual/Multi-BGP session strategy and
   CCDR architecture, to meet the above requirements in dynamical and
   central control mode. Future PCEP protocol extensions to transfer the
