N2 - Many Internet users use P2P live streaming services which deliver live video contents to many users. In the services, the video content is sliced into small pieces called chunks. The peers not only receive but also send the chunks to watch the video contents. Source's load for delivering is reduced. In an Offer Select method, each peer offers sendable chunks to it's neighbors. The neighbors select receiving chunks from the sendable chunks. However, some chunk diffusions are low. Each peer sends chunk independently. It happens that peers offer same chunks to a neighbor. In this paper, we propose a chunk schedule method. Each peer receives chunks which the nearby peers hardly possess. Our method reduces dispersion of chunk diffusion. Simulation results show that peers receive more chunks, which enables peers to watch higher quality.
