SDIGraph: Graph-based Management for Converged Heterogeneous Resources in SDI

In Software Defined Infrastructure ( SDI), a network topology consists of many converged heterogeneous resources, both physical and virtual, for computing and networking. However, the network topology is dynamic due to various physical and logical activities such as addition of new racks, VM addition/deletion/migration, and network creation/modification/deletion. In this paper we propose SDIGraph, which is a graph-based topology management service, for such dynamic, converged, and heterogeneous infrastructure resources in SDI. For modeling the topology, we use a graph model for representing converged heterogeneous resources and their associations. We also use a graph database to enable us to efficiently store resources and to make queries based on graph traversal and indexing. We develop a prototype for how to get a network topology in the SAVI Testbed which is an operational facility based on SDI deployed over much of Canada.
