In this thesis, a modular environment, called M5, for modelling, simulating and analysing multimedia conferencing over interconnected homogeneous and heterogeneous networks is described. The modular architecture is a key feature of M5. It provides the environment with the flexibility for incorporating different protocols models and network configurations. It is able to handle both high-level discrete events for traffic modelling, and low-level analytical functions, commonly in a continuous form, for modelling attributes such as throughput and delay. The modular approach also provides an easy way to interface different functional modules, thus a simulation of the heterogeneous networks becomes feasible. M5 has been equipped with functional modules for network specification, traffic modelling, traffic distribution, visualisation, and system control. Two popular network protocols, namely CSMA/CD and ATM, have been integrated into M5 as network simulation modules. These modules have been implemented as computational engines based on the statistical models of the corresponding protocols. The use of statistical models provides a means to obtain simulation results in a reliable, consistent and cost effective manner. In addition, M5 also provides a MCU module for the simulation of multipoint multimedia conferences, where MCUs are used extensively for multipoint control in packet based multimedia communication systems. This research has clearly shown that a modular architecture is a key to the development of an integrated software environment for simulating complex networks and multimedia communication traffic. It is beneficial to maintain high-level modelling in a discrete form in order to facultative intuitive and meaningful traffic specification, while utilising analytical models for low-level simulation, which can be implemented in a more flexible and cost-effective manner. A part of this thesis was presented by the candidate at the International Conference on Communication Technology held in Beijing in August 2000 (IEEE Catalogue 00EX420).
