               A YANG Data Model for Service Information
                 draft-wang-service-information-yang-00

Abstract

   Computing-Aware Traffic Steering (CATS) aims to solve the problem of
   how the network edge can steer traffic between clients of a service
   and sites offering the service.  To achieve such scheduling, the
   network needs to aware the computing information of the service.
   This document defines a YANG data model for the computing information
   of the service for CATS.

1.  Introduction

   Computing-Aware Traffic Steering (CATS) [I-D.ldbc-cats-framework]
   aims to solve the problem of how the network edge can steer traffic
   between clients of a service and sites offering the service.  To
   achieve such scheduling, the network needs to aware the computing
   information of the service.  The awareness methods are not limited to
   distributed, centralized, or
   hybrid[I-D.yao-cats-awareness-architecture].  This document defines a
   YANG data model for the computing information of the service
   transferring between the CATS-control center and the CATS-routers.
   Naturally, this data model could also be used for distributed
   solution.

1.1.  Tree Diagram

   This section presents a simplified graphical representation of the
   computing information model using a YANG tree diagram[RFC8340].
