Notes	Yue Guangxue,Song Jiajia,Xiong Xiaofeng,Liu Jiansheng（1.School of Science,Jiangxi University of Science and Technology,Ganzhou 341000,China; 2.Department of Information Engineering,Jiaxing University,Jiaxing 314000,China） 11-2103/TN P2P streaming media; quality of service; reputation; incentive; scheduling With the quickly development of science,streaming media application has become one of the main services over internet.How can it support the large-scale customers and improve the quality of service.Based on the characters of P2P,it compares and analyzes the typical flow service strategy of media streaming system,and summarizes the features and shortcomings of different systems.Moreover,it takes the node selection,data scheduling,cache mechanism,error-tolerance,and incentive mechanism as the evaluation index,focuses on the quality of service of current typical streaming media system.Finally,future works about the quality of service of media streaming systems in P2P networks are outlined.
