The combination of social network and P2P streaming service created a new kind of peers, these peers only share their bandwidth to social-connected peers and they do not need to watch the streaming video. Because of the particularity of such peers, ordinary P2P modelsdo not apply to this type of peers. Therefore, we propose a social network-based bandwidth sharing model. By creating download and upload neighbor list, our model separates the transmission of data blocks. Peer requests data blocks from peers in download neighbor list by the data block missing degree of peers in upload neighbor list. Meanwhile we redefine the buffer of social-connected peers, make the social-connected peers better collaborate with the sharing peers. Therefore the social-connected peers will not receive duplicate data blocks. Experiment data shows our sharing model could maximize the sharing ratio of sharing peers, and improve the playback quality of social-connected peers. When the number of sharing peers reaches a certain proportion, the playback delay of P2P streaming service with sharing peers is better than the playback delay of normal P2P streaming service.
