P2P Live media streaming is becoming popular in the Internet. There still remain some neglected problems such as playback lag, which is extremely sensitive for users in some urgent and interactive scenarios. In addition, many current studies were based on theoretical assumptions and never be turned into reality. In this paper, we present SonicStream, a full implementation of live P2P media streaming system with consideration of improved playback lag, the prototype of which is inspired by R2. Experimental evaluation testifies a performance improvement in terms of playback lag.
