This work describes the process of efficiently streaming video through peer-to-peer connections to multiple heterogeneous and asynchronous clients. In the proposed p2p patch transmission scheme, all peers are organized into a tree structure. Every peer receives video frames from its parent and shares with its children. The optimal proxy prefix cache allocation is calculated for the proposed transmission scheme to identify cache length of videos to minimize the aggregate transmission cost. Experimental results demonstrate that the proposed scheme can lead to significant transmission cost savings and outperforms the server-proxy-client based transmission schemes.
