摘　　要：针对Chord不支持多属性查找,通过分析结构化覆盖网络Chord,提出了SM-Chord。该系统充分利用各个节点的自身性能来维护自己的资源,以资源的多个属性值构成Chord环,从而使该系统既可以支持多属性查找,又可以减少资源重新部署带来的带宽消耗。仿真试验结果表明,SM-Chord在保持Chord查找成功率的同时,能够通过负载分担提高系统的负载平衡能力,并且降低了系统的带宽消耗。To solve Chord does not support for multi-attribute to fred, a new Chord named SM-Chord is proposed after comparison and analyzed various overlay networks such as Chord. The system makes full use of the system＇ s own performance of the various nodes to maintain their own resources, and multi-attribute of resource make up of Chord ring. So the system support multi-attribute search, and reduce bandwidth consumption which caused by the redeployment of resources. Through analysis and simulation experiments show that the SM-Chord maintain the success rate of Chord, reduce the load of hot spot and achieve load balance and reduce bandwidth consumption.
