1.  Introduction

   Currently, a data center network is composed of single or multiple
   fabrics which are also known as PODs (a Point Of Delivery), which may
   be heterogeneous due to implementation of different technologies
   within these fabrics.  For example, within a DC network, Fabric A may
   use VXLAN while Fabric B may use VLAN.  The management of the entire
   heterogeneous network will be sophisticated and complex especially
   when the DC network scales.

   However, in this heterogeneous DC network, fabric can be considered
   to be an atomic structure to provide network management and services,
   as well as capacity scaling.  From this point, the management of the
   entire DC network can be broken down into management of these fabrics
   as to provide easier management and flexibility and scalability.

   With this purpose, this document defines a YANG data model for the
   Fabric topology of Data Center Networks by using YANG [6020][ I-
   D.draft-ietf-netmod-rfc6020bis-09].  To do so, it augments the
   generic network and network topology data models defined in [I-
   D.ietf-i2rs-yang -network-topo] with information specific to a DC
   fabric.

   This model defines the generic configuration and operational state
   for the DC fabric common to all vendor implementation, which can be
   extended by vendors with specific information.  This model can be
   used by the network elements to expose to a network controller and
   capture their understanding of the overall network topology.  Also,
   it can be used by a network controller to represent its view of the
   fabric topology that it controls and expose it to applications for
   network management for Data-center networks.
