| 摘 要： | Chord是一种比较成功的结构化P2P路由算法,但是网络节点性能的差异,影响了整个系统的效率;网络中一部分节点的频繁加入和退出所引起的系统震荡也影响了系统的性能;同时,结构化系统不提供相关节点的匿名性,也是结构化系统的一个不足之处.本文利用节点性能的差异,提出了基于超级节点的Chord路由算法,在Chord系统中形成节点簇,不但提高了系统的效率,而且能够有效地处理系统震荡问题,同时,为Chord系统提供了一定的匿名性.

| Abstract: | Chord is a successful structured P2P routing algorithm,but the heterogeneity of peers affects the efficiency of the system.And it brings system shaking because of a part of the peers in the network joining and leaving frequently.It's also a disadvantage that structured systems don't provide mutual anonymity.Taking advantage of the heterogeneity of capabilities across peers,we propose new Chord routing algorithm based on Super-Peer,not only to improve the efficiency of system,but also to deal with system shaking efficiently,at the same time,it could provide mutual anonymity. |
