         A YANG Model for IP Link and Transport Service Mapping
           draft-fu-pce-ip-link-transport-service-mapping-01

Abstract

   IP+optical is a cross-layer collaboration technology for unified
   management of IP and optical networks.  Based on framework proposed
   in [ACTN-FWK][I-D.ietf-teas-actn-framework], this draft presents
   specific information about the IP+optical solution: hierarchical
   controllers + disabled GMPLS UNIs.  This solution does not involve
   UNI tunnel objects.  Therefore, the mapping between IP links and
   transport services is key point of this solution.  This draft
   provides a YANG model for the RESTCONF/NETCONF protocol.  This YANG
   module defines NBIs for the IP+optical super controller.

1.  Introduction

1.1.  IP+optical solution

   IP+optical is a cross-layer collaboration technology for unified
   management of IP and optical networks.  IP+optical adopts the C/S
   architecture, where the IP network is the client-layer network and
   the optical network is the server-layer network.  The mapping between
   IP-layer IP links and transport services is the key ability of an
   IP+optical network.  Through the mapping, the services of IP layers
   and those of transport layers can be associated to implement use
   cases of IP+optical scenarios.

   IP+optical use cases include multi-layer topology visualization,
   automated network deployment, multi-layer automated service
   deployment, multi-layer protection and restoration, multi-layer
