The IESG has approved the following document: - 'A YANG Data Model for Fabric Topology in Data Center Networks' (draft-ietf-i2rs-yang-dc-fabric-network-topology-12.txt) as Proposed Standard This document is the product of the Interface to the Routing System Working Group. The IESG contact persons are Alvaro Retana, Deborah Brungard and Martin Vigoureux. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-dc-fabric-network-topology/ Technical Summary This document defines a YANG data model for fabric topology in Data Center Network. Normally, a data center (DC) network is composed of single or multiple fabrics which are also known as PODs (Points Of Delivery). These fabrics may be heterogeneous due to implementation of different technologies when a DC network is upgraded or new techniques and features are enrolled. The configuration and management of such DC networks with heterogeneous fabrics will result in considerable complexity, requiring a fair amount of sophistication. As a basis for DC fabric management, this document defines a YANG data model [6020][7950] for fabric-based data center topology. To do so, it augments the generic network and network topology data models defined in [I-D.ietf-i2rs-yang-network-topo] with information that is specific to Data Center fabric networks. Working Group Summary There was solid consensus in the working group to take on the work both on the list, and at IETF meetings. Document Quality There is an implementation of this yang data model.
