| 摘 要： | 针对Chord协议的指取表在对比试验中表现欠佳,对其关键数据结构—指取表进行优化。原Chord协议的指取表采用具有折半查找性质的分布,在仿真实验中,采用了域内均匀分布的指取表,取代了原有指取表。仿真试验结果表明,在节点数固定的Chord环中,新的指取表的效率比原有协议的效率高,与F-chord的效率大致相当,明显改善了网络的性能,提高了搜索效率。

| Abstract: | Optimized finger table which is a key data structure of Chord protocol was proposed in recent research since the old table's performance was not very good in a comparative trial.The old table of Chord protocol uses the distribution of Binary Search.In the simulation experiments,it has been taken place by a table named intra-domain uniform finger table.The simulation result shows that the performance of the new finger table is better than original Chord and equals with the efficiency of F-chord protocol.It i... |
