摘　　要：针对云计算用户、服务、供应商和数据中心的密度不断增长导致传输数据、网络流量和基础设施的大量能耗问题,提出一种高效节能路由算法。其目的是在用户和数据中心间定位出最低能耗路线,同时确保用户需求。首先,对用户到数据中心的连通性进行建模,分析了网络拓扑结构;然后,为了最简化用户意图以及最小化能耗,通过遍历节点最小数的基线最短路径算法进行评估,将用户任务通过最节能路径发送到数据中心,从而最小化能耗和服务响应时间(SRT)。实验的网络拓扑结构使用互联网服务提供商(ISP)的分支设计。实验结果表明,该算法具有更短的路由路径长度和更低的路由能耗。此外,最短路径方法只有在成功发送或接收之后才能确定最节能的路由。Concerning large energy consumption of data transmission,network traffic and infrastructure caused by the density growing of cloud computing users,service providers and data center,this paper proposed an energy efficient routing algorithm.The goal was to locate the minimum energy consumption path between the user and the data center,and to ensure the user needs. First of all,it modeled the connectivity between user and data center and analyzed the topological structure of the network. Then,in order to simplify the intentions of user and minimize energy consumption,it evaluated through baseline shortest path algorithm by traversing nodes. It transmitted user tasks to a data center through the most energy-efficient path,which minimized the energy loss and service response time( SRT). It used the branch of Internet service provider( ISP) to design the network topology. Experimental results show that the proposed algorithm has shorter routing path length and lower routing energy consumption. In addition,the shortest path method can determine the most energy-efficient routing only after successful transmission or reception.
