A generic object-oriented model for representing computer network topologies

This paper presents a generic model based on an object-oriented approach fo r representing computer networks in topological design. The modeling approa ch used is based on Rumbaugh's OMT methodology and integrates four essentia l interdependent steps. The implementation of this model has resulted in a tool called DESNET, which is useful for several levels of users. DESNET all ows to extract from a database an already captured network, to capture and store a new network, and to cancel an existing one. It also allows the user to select routes through a network, to assign flows and capacities to link s, and to evaluate network performances. DESNET can be considered as a prac tical tool, which can be used by network designers for topological design, link sizing and capacity planning purposes. (C) 2001 Elsevier Science Ltd.
