SM-Chord:自维护的多属性Chord

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.

SM-Chord: self-maintenance based multi-attribute Chord

To Solve Chord does not support for multi-attribute to find, a new Chord named SM-Chord is proposed after comparison and analyzed various overlay networks such as Chord.The system makes fuIl 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.
