由于未考虑实际网络拓扑结构 ,当前结构化对等网络系统存在高延迟低效率的毛病 .本文提出一种与实际网络拓扑结构相关的路由方法 ,并开发出一种基于Chord的TaChord系统 .在仿真系统中 ,用物理跳数、域间延迟和每个消息占用的带宽来衡量TaChord和其他系统的路由性能 .仿真结果表明 ,TaChord系统的路由性能有了极大的提高 ,如平均物理跳数是Chord的一半 ,并且不同路由缓存管理策略对TaChord的路由性能能产生重要的影响 .
Because of not considering the actual network topology structure, the current structured peer-to-peer network system has the problem of high latency and low efficiency.This paper proposes a routing method related to the actual network topology and develops a Chord-based TaChord system.In the simulation The system measures the routing performance of TaChord and other systems by using the number of physical hops, the inter-domain delay and the bandwidth occupied by each message.The simulation results show that the routing performance of TaChord system has been greatly improved, for example, the average number of physical hops is Chord half, and different routing cache management strategy TaChord routing performance has a significant impact.
