结构化P2P网络Chord中节点行为优化的研究

为了提高结构化P2P网络系统Chord的性能,解决节点频繁地加入和离开带来的网络波动和高的维护代价,提出了一种新颖的节点行为优化的方法.通过对节点行为的策略控制,用较小的存储开销和节点的额外负载换取网络整体性能的提高。网络仿真结果显示,节点的优化有效地控制了Chord环的大小,增加了容错性,提高了系统的整体性能.

Optimized node action of chord in structure-P2P networks

In order to enhance the performance of Chord in structure-P2P networks and resolve the networks fluctuation and high maintenance costs caused by the join and exit of nodes,an novel way is introduced.Depending on the efficient control of the action of nodes,it exchanges the little storage and the extra load for improvement of Chord.The result of simulation shows that Optimizing the action of node can control the size of ring in Chord and increase the quality of tolerate-fault and thus improves the whole system.
