摘要:

基于 维star connected cycle (SCC)拓扑图首次提出了一种常量小度数的对等网络构造方式SCC-DHT,它采用分布式哈希表(DHT)的思想进行有效地资源查找定位,网络节点之间的覆盖连接则是参考SCC拓扑图,使得每个节点在维持 个邻居节点度数的前提下,资源查找路径为 .实验结果表明, SCC-DHT具有更好的健壮性和可扩展性.

关键词: 对等网络, 分布式哈希表, SCC拓扑图, 常量小度数

Abstract:

A constant-degree peer-to-peer network constitution based on d dimension star connected cycles(SCC) graph was presented firstly, namely SCC- distributed Hash table (DHT). It adopts DHT to search and locate resource, and the connection of network nodes are covered and connected according to SCC graph. SCC-DHT achieves a time complexity of logic hop per lookup request by using neighbors per node. The simulation results show that SCC-DHT has better robustness and expansibility.

Key words: peer-to-peer network, distribute Hash table, star connected cycles graph, small constant-degree
