A graphical methodology for simulating communication networks

A novel approach for simulating communication networks is discussed and illustrated with two examples of a token-passing network. The method is based on a graphical representation of the network consisting of three components: topology, nodes, and protocols. The topology and nodes are drawn to a network specification. The protocols are drawn by using Petri nets with some extended features. A simulation model can be automatically generated from this representation. Results of the simulation are compared to those of an analytical model, showing excellent agreement.<
