A Study on Peer Startup Process and Initial Offset Placement in P2P Live Streaming Systems

Free registration required

Executive Summary

In this paper, the authors measure and study the peer startup process in PPLive, a popular commercial P2P streaming system, and focus on a fundamental issue in this aspect: how a peer initializes its buffer when it joins a channel, i.e., initial offset placement of peers' buffers in the startup stage. They build a general model of peer startup process in chunk-based P2P streaming systems and present an initial offset placement scheme they inferred from the measurement results, i.e., Proportional Placement (PP) scheme. With FP scheme, the initial buffer offset is set to the offset of the reference neighbor peer plus an advance proportional to the reference neighbor peer's offset lag or buffer width.
