This work is motivated by the current trends in future broadband communication networks. On the one hand, the latest developments and experimentation with the Asynchronous Transfer mode (ATM) technology shows that that ATM is going to be the future transport mechanism in many private and public networks. This is driven by the need to efficiently support a large population of widebandlbroadband users with different data traffic characteristics and certain Quality of Service (QoS) guarantees. On the other hand, the interest in satellites and their role in the future broadband multimedia communications systems, has grown considerably since they can very quickly and economically extend the boundaries of the terrestrial mobile and fixed networks coverage. On-board satellite signal regeneration and' ATM-like' switching is part of the latest experimental developments by many payload manufacturers. In this thesis, the focus is on the Grade of Service (GoS) and QoS provisioning in future broadband satellite multimedia systems by introducing new means for their performance evaluation. The investigation includes modelling techniques for both Geostationary (GEO) and non-GEO systems. An extensive set of representative results derived analytically and by simulation are presented assuming different mixed traffic scenarios. A new methodology for the Available Bit Rate (ABR) service class capacity estimation and the CAC strategy that needs to be adopted in S-ATM systems is developed. Moreover, the performance evaluation of bandwidth reservation techniques for non-GEO satellite constellations is investigated and new rules for maintaining specified GoS performance are proposed. This work contributes towards the definition of a satellite network infrastructure that best satisfies the requirements of an integrated solution with Broadband-Integrated Services Digital Network (B-ISDN).
