摘要
本文对一种新型的视频点播系统P2Cast视频点播系统的关键技术进行了研究,针对段阈值在系统的可扩展性方面以及视频服务质量方面所起的重要作用,结合补丁流算法和客户节点的请求速率提出了一种嵌入动态调节段阈值机制的BF改进算法。该算法在一定程度上提高了P2Cast视频点播系统的性能。
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.
