Improving the Scalability of P2P Streaming Based on Fine-Grained Balancing Scheme
Chow‐Sing Lin, Wei-Ting Syu, I-Ting Lee · 2008
In this paper, we relax the restriction of only one designated description forwarded by a peer described in our previously proposed balancing scheme and propose the fine-grained balancing scheme to further improve the scalability of P2P live streaming network based on multiple description coding (MDC) techniques. Like the balancing scheme, the fine-grained balancing scheme is capable of balancing the distribution of descriptions and peer loading by a centralized description allocation scheme. In addition, according to our analysis, its flexibility of selecting desired descriptions and source peers favors the utilization of the aggregate bandwidth of P2P network. The performance study shows that our fine-grained balancing scheme can successfully reduce the consumption of server bandwidth and the rejection rate so that more clients can be served.
