RESUMO

Video services are both a major business driver and a bandwidth consumer for the future broadband integrated network (B-ISDN). Understanding different video services requirements is of paramount importance for network design. In this dissertation we study Distributed Home Theatre (DHT), a video service which allows distributed users to debate a film. We investigate the tradeoff between bandwidth reduction and program replication in the network design for the provision of the DHT services. We propose a framework to analize this tradeoff for real costs. We analize different network scenarios: networks without stream sharing, networks with stream sharing, networks with distributed servers and networks with distributed servers and stream sharing. Serverlcache replication techniques are investigated and evaluated under different user distribution and different number of users per DHT session. Moreover, we analyze networks with both DHT and video on demand services
