First-Aid Mechanism for Peer-to-Peer Streaming

A fundamental challenge in P2P streaming system is how to provide high quality of services (QoS), such as short startup time, low seeking latency and high playback continuity. This paper presents First-Aid mechanism, a reciprocal data-request scheme in which first-aid users have high priority to get data while they must provide service to normal users suspended by them. Experiments show that our scheme performs better than traditional methods. We have also implemented a scalable P2P system called Cool-Fish[1] which supports live-streaming, VoD and file sharing services. The running results also prove the validity of our design.
