Abstract：Current media streaming systems are often based on the client-server framework and IP-level multicasting supported by ISP, which limits clients amount to a great extent. In P2P network, each client receives data and forwards it to others at the same time. So large numbers of clients resource ignored before can be effectively used. Firstly challenges in P2P media streaming applications were pointed out, then some recent research results such as application-level multicast tree, heterogeneity of network and incentive mechanism and so on were introduced. Some existent problems and some remained issues for further research were discussed.
