Using Petri nets for performance analysis of two-terminal parallel-series communication networks

Abstract The problem of performance analysis of two-terminal parallel-series networks has been considered using the concepts of Petri nets. The reachability and firing concepts of Petri nets are utilized to derive interpreted modules of series and parallel connection in terms of reachability matrix. These independent modules are then subjected to analysis for the evaluation of software parameters, e.g., execution time, reliability, etc. The performance evaluation of any two-terminal parallel-series network is then reduced to its decomposition in terms of these modules, which do not change the structural behaviour and the functioning of the network. It simply changes the firing of certain transitions in the modeled system. The preposed treatment for interpreted modules seems to be sufficient for studying the dynamic behaviour of any kind of the networks at different level of abstractions.
