摘　　要：P2P系统中分配及检索目标的路由占据了大多数开销,通过公平性参数(FI)推导出影响路由公平性的因素,根据结论在没有增加任何负载的情况下对Chord finger选择算法进行改进,通过公平性参数(FI)及仿真对改进前后的Chord的公平性进行评估,结果表明改进后的EChord性能有较大提高。The distribution and retrieval routings in P2P system accounted for the majority of the routing spending, so derives the factors that affect the fairness of the routing, through the fairness parameter and then according to the conclusion, improves Chord finger selection algorithm without any additional load, assesses the fairness of Chord before and after improvement by the fairness parameter and simulation, the performance result shows that the EChord has been greatly improved.

关 键 词：P2P 路由公平性 EChord
