Scalability and Efficiency of Push-Driven P2PTV Systems
TeleVision transmitted over IP (IPTV) presents numerous opportunities for users as well as service providers, and has attracted significant interest from industry as well as research communities in recent years. Among the emerging IPTV delivery architectures, the peer-to-peer based delivery mechanism is considered attractive due to the relative ease of service deployment and potential bandwidth savings. However, the question of how well P2PTV networks would support a growing number of users has not been fully investigated so far. In this paper, the authors try to address this question by studying scalability and efficiency factors in a typical P2P based live streaming network.
