TreoStream: A peer-to-peer streaming media system prototype

A core issue that confronts peer-to-peer streaming media application is to efficiently schedule the propagation of data segment. This paper presents a peer-to-peer scheme based on principal-agent model (PAM) that some peers play the role of agent, to gather the information of principal peers in its local physical network, which can be used to optimizing of data scheduling. We designs and implements a peer-to-peer streaming media system prototype based PAM, which called TreoStream. Experiments show that TreoStream can improve the efficiency of data scheduling, without increasing the traffic overhead of system.
