The peer-to-peer file sharing application has become increasingly popular for Internet users since the 1999 introduction of Napster. In the past decade, several more applications have been invented, such as Gnutella, FastTrack, Chord, Freenet, and BitTorrent. However, all of these applications use the downloading method that requires the source to be downloaded from one or more resources to one requesting peer. Now, alternative methods of file sharing delivery have been introduced; some examples include CELL, CollectCast, DAC, and GnuStream dan PAST, all of which use streaming to deliver media content to the user. Because peer-to-peer file sharing and streaming systems- such as Video on Demand and IPTV - are popular among Internet users, developers and researchers have a tendency to combine the Video on Demand and peer-to-peer topology into one system. This way, the channel program of Video on Demand or IPTV can be inexpensively distributed on the Internet by utilizing the availability of peers; each peer becomes both a receiver and a supplier to another peer. Many problems are associated with media streaming of file sharing applications, some of which include query-saturated networks, high latency in locating content, attempting to preserve uninterrupted streaming sessions, high peer load, flash crowds, and bottlenecks. As such, proposed system has been introduced in an effort to reduce the maintenance cost of overlay network topology, the routing and access costs of lookup services, and to service costs of streaming sessions. Proposed system is a combination of pure, client-server, and hierarchical peer-to-peer topology, and is categorized as a hybrid peer-to-peer business model. Five experiments, consisting of four simulations and an expert evaluation, have been executed to determine the performance, scalability, maintenance, reliability and usability. The results reveal that proposed system can improve the quality of file sharing applications by reducing path length, peer load, and total usage while maintaining the overlay network topology in various chum rates, as well as locating a file in lookup services. The results also show that proposed system has sufficient scalability whenever the network size and number of queries increase.
