               YANG Data Model for Segment Routing Policy
               draft-thomas-spring-sr-policy-yang-00.txt

Abstract

   This document defines a YANG data model for Segment Routing (SR)
   Policy that can be used for configuring, instantiating, and managing
   SR policies.  The model is generic and apply equally to the MPLS and
   SRv6 instantiations of SR policies.

1.  Introduction

   The Network Configuration Protocol (NETCONF) [RFC6241] defines
   mechanisms to manage network devices.  YANG [RFC6020] is a modular
   language that represents data structures in an XML tree format, and
   is used as a data modeling language for the NETCONF.

   Segment Routing (SR), as defined in
   [I-D.ietf-spring-segment-routing], allows a headend node to steer a
   packet flow along any topological path and/or service chain.  The
   headend node is said to steer a flow into a Segment Routing Policy
   (SR Policy).  An SR policy is a framework
   [I-D.ietf-spring-segment-routing-policy] that enables instantiation
   of an ordered list of segments on a node for implementing a policy.
