Abstract:

This paper studies the key technique used in a new VoD system called the P2P patching scheme VoD system. Since the session threshold plays an importan t role in the scalability and QoS of the P2Cast VoD system, a new BF algorithm embedded with the adaptive session threshold strategy is presented. The s trategy combines with the patching algorithm and arriving rate of client nodes. This algorithm improves the performance of the P2Cast VoD system.
