一种基于对等网络的云资源定位算法
发布时间：2018-11-21 15:08
【摘要】：提出用分布式哈希表(DHT)为每台云服务器产生一个唯一的节点编号,该编号作为网络拓扑结构、检索信息存储和信息查询共同的标志符,从而形成一个适合分布式计算的结构化P2P覆盖网。设计了新的拓扑和路由协议来解决云资源的常数跳定位问题。仿真实验表明,经典的P2P算法平均查找跳数与网络规模成正相关,无法依据云计算的实际需要人为地控制查找跳数;该算法的平均查找跳数与网络规模无关,随着网络规模的增大而趋向于设定值,可以解决云资源的常数跳定位问题。
[Abstract]:A distributed hash table (DHT) is proposed to generate a unique node number for each cloud server, which is used as a network topology to retrieve information storage and common identifier for information query. Thus, a structured P2P overlay network suitable for distributed computing is formed. A new topology and routing protocol are designed to solve the problem of constant hop localization of cloud resources. The simulation results show that the average search hops of the classical P2P algorithm are positively correlated with the network size and can not be artificially controlled according to the actual needs of cloud computing. The average search hops of this algorithm are independent of network size and tend to set values with the increase of network size, which can solve the problem of constant hop localization of cloud resources.
