Abstract

With the growing popularity of P2P live streaming, more and more channels have been set up, however, this poses new challenges to P2P technology, such as stronger dynamic characteristic, high switching delay. In this paper, we focus on the server, which can allocate different bandwidth to meet the needs of each type of peers, especially the switching peers. On a close study of the basic tradeoff between the switching peers' and overall performance, we propose new peers first strategy and adaptive bandwidth allocation, and get a satisfactory result. Our results show that the full and rational utilization of server bandwidth is of great help for improving the performance of multi-channel P2P live streaming.
