On Peer-to-Peer Media Streaming

In this paper, we study a peer-to-peer media streaming system with the following characteristics: (1) its streaming capacity grows dynamically; (2) peers do not exhibit serverlike behavior; (3) peers are heterogeneous in their bandwidth contribution; and (4) each streaming session may involve multiple supplying peers. Based on these characteristics, we investigate two problems: (1) how to assign media data to multiple supplying peers in one streaming session and (2) how to fast amplify the system’s total streaming capacity. Our solution to the first problem is an optimal media data assignment algorithm OTSp2p, which results in minimum buffering delay in the consequent streaming session. Our solution to the second problem is a distributed differentiated admission control protocol DACp2p. By differentiating between requesting peers with different outbound bandwidth, DACp2p achieves fast system capacity amplification; benefits all requesting peers in admission rate, waiting time, an...
