Abstract: In this paper, the use of coloured generalized stochastic Petri nets (CGSPNs) is considered as a tool for protocol performance modelling of integrated systems. Neutral tokens are used and the CGSPNs are extended by introducing priority firings for different colours. It is shown that the underlying stochastic process of the extended CGSPNs is still Markovian, and numerical solutions can be obtained by a software package. As a direct application, the use of the extended CGSPNs to model an integrated data voice system is explained. The performance of the integrated system protocol is evaluated by numerically solving the CGSPNs model.
Keywords: coloured generalized stochastic net; protocol performance; priority firings (for different colours); Markov process; integrated voice/data system.
