                  A Data Model for Network Topologies
                draft-ietf-i2rs-yang-network-topo-00.txt

Abstract

   This document defines an abstract (generic) YANG data model for
   network/service topologies and inventories.  The model serves as a
   base model which is augmented with technology-specific details in
   other, more specific topology and inventory models.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
