摘要
在P2P网络中,节点如何存储并与其他节点交互数据信息,对于协议的性能有重要的影响。本文提出了一种基于按位运算的数据片断选择方法,该算法使用二进制序列存储并传递数据片段信息,利用按位运算来降低运算复杂度,加快运算速度。仿真结果表明,该方法可以明显地降低数据获取的延迟,改善系统的播放流畅度。
It plays an important role in performances of protocols in peer to peer networks of how to store and communicate data information with other peers. A new selection algorithm based on BIT operation for datapiece information is presented. The storage overhead and communication overhead of peers is reduced by using binary sequences to store and change information of available data pieces between peers. And the algorithm is of low complexity and of high efficiency. Simulation results show that the delay of data delivery is decreased, and the playing fluency is improved.
