Reliable Live Broadcast Architectures Based on P2P

Though P2P (peer-to-peer) technology makes it possible that the number of the clients can be infinite, P2P technology still has some problems, for instance, instability and fluctuation, which may influence the quality of service (QoS). In this paper, two novel P2P-based architectures are proposed, which can avoid the system fluctuation caused by the new joining nodes or the departing nodes. And a new incentive mechanism is introduced, which can well motivate the clients to be seeding server. Analysis of the number of the nodes and the benefits of the issuers shows that this incentive mechanism can guarantee system reliability and solve the problems of scalability, QoS, and the benefits assignment of the server issuers.
