| 摘 要： | Chord算法是结构化P2P网络的经典算法。Chord具有很多优秀特性,但仍存在一定局限：节点异构性、负载均衡、热点资源问题与底层物理拓扑。从路由效率、负载均衡、拓扑匹配几个角度改进Chord,并在此基础上提出基于资源性能和热度的Hot-Chord。充分考虑节点异构性和底层物理拓扑结构,引入局部负载均衡,建立热环,提高热点资源搜索效率,从而提高性能。

| Abstract: | Chord is one of the most classical algorithms of the structured P2P network.It has a lot of excellent features.However there are still some limitations： node heterogeneity,load balancing,hot resources and the physical topology.Chord was improved in the above aspects.Then Hot-Chord algorithm was proposed considering resource performance and physical topology.Resource search efficiency and performance was enhanced by region load balance and the circle of resource nodes with high performance. |
