Improving Streaming Capacity InMulti-Channel P2P VoD Systems Via Intra-Channel and Cross-Channel Resource Allocation
Multi-channel Peer-To-Peer (P2P) Video-on-Demand (VoD) systems can be categorized into independent-channel P2P VoD systems and correlated-channel P2P VoD systems. Streaming capacity for a channel is defined as the maximal streaming rate that can be received by every user of the channel. In this paper, the authors study the streaming capacity problem in multi-channel P2P VoD systems. In an independent-channel P2P VoD system, there is no resource correlation among channels. Therefore, they can find the average streaming capacity for the independent-channel P2P VoD system by finding the streaming capacity for each individual channel, respectively. They propose a distributed algorithm to solve the streaming capacity problem for a single channel in an independent-channel P2P VoD system.
