PP2P streaming today uses constant bitrate video, primarily because it is easier to cut such video into substreams and deliver it via multiple peers. The same method suffers from low reliability of end-to-end throughput which can cause playback freezes. This paper proposes a variable-bitrate method for P2P streaming which solves this problem. The proposed method outperforms traditional P2P streaming by a large margin and provides a highly resilient streaming platform.
