   YANG Data Model for Fabric Service delivery in Data Center Network
              draft-zhuang-i2rs-dc-fabric-service-model-05

Abstract

   This document defines a YANG data model that can be used to deliver
   fabric service for users within a data center network.  This model is
   intended to be instantiated by management system.  It provides an
   abstraction of services for a fabric network to be used by users.
   However it is not a configuration model used directly onto network
   infrastructures.  It should be used combining with such as fabric
   topology data model defined in
   [I-D.zhuang-i2rs-yang-dc-fabric-network-topology] with specific
   fabric topology information to generate required configuration onto
   the related network elements to deliver the service.

1.  Introduction

   Network service provisioning is currently coupled with specific
   network topology and technology applied, which is technology and
   device oriented.

   In the area of data center, this approach makes the management
   complex due to massive network devices involved and various
   applications deployed by multiple users (also known as tenants).

   In the traditional way, the administrator has to be aware of the
   entire data center network before delivering services for users.
   When service request comes up, administrator has to divide the
   request into appropriate configurations and operations for all
