| 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 important 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 strategy combines with the patching algorithm and arriving rate of client nodes. This algorithm improves the performance of the P2Cast VoD system. |
