1. Introduction
Normally, a data center network is composed of single or multiple
fabrics which are also known as PODs (a Point Of Delivery). These
fabrics may be heterogeneous due to implementation of different
technologies while DC network upgrading or enrolling new techniques
and features. For example, Fabric A may use VXLAN while Fabric B may
use VLAN within a DC network. Likewise, a legacy Fabric may use
VXLAN while a new Fabric B implemented technique discussed in NVO3 WG
such as GPE[I-D. draft-ietf-nvo3-vxlan-gpe] may be built due to DC
expansion and upgrading. The configuration and management of such DC
networks with heterogeneous fabrics will be sophisticated and
complex.
Luckily, for a DC network, a fabric can be considered as an atomic
structure to provide network services and management, as well as
expand network capacity. From this point of view, the miscellaneous
DC network management can be decomposed to task of managing each
fabric respectively along with their connections, which can make the
entire management much concentrated and flexible, also easy to
expand.
With this purpose, this document defines a YANG data model for the
Fabric-based Data center topology by using YANG [6020][7950]. To do
so, it augments the generic network and network topology data models
