An overlay network architecture for data placement strategies in a P2P streaming network

Generic file sharing P2P applications have gained high popularity in the past few years. In particular P2P streaming architectures have attracted attention. Some of them consider many-to-one streaming or high level multicast techniques. In contrast to these models we propose techniques and algorithms for point-to-point streaming in autonomous systems as it might occur in large companies, a campus or even in large hotels. Therefore we introduce the architecture of an overlay network. Each subnetwork contains local active rendezvous server (LARS) which do not just act as directory server but also control availability of movie content in their subnetwork. Due to this we consider data placement strategies depending on restrictions of network bandwidth and peer capabilities as well as the movies´s access frequency.
