云环境下利用用户到数据中心建模的高效节能路由算法

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,提出针对云数据的高效节能路由算法。其目的是在用户和数据中心之间定位出最低能量消耗路线,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；然后为了用户意图最简化和能量最小化,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,从而最小化能量损耗和服务响应时间(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。实验结果表明提出的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。

Energy Efficient Routing Algorithm by Modeling in Data Center under Cloud Environment

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, an energy efficient routing algorithm for cloud data is proposed. The goal is to locate the minimum energy consumption path between the user and the data center, and to ensure the user needs. First of all, the connectivity between user and data center is modeled and the topological structure of the network is analyzed. Then, in order to simplify the intentions of user and the energy consumption, and it is evaluated through baseline shortest path algorithm by traversing the lest nodes. User tasks are transmitted to a data center through the most energy-efficient path, which minimizes the energy loss and service response time (SRT). The network topology is designed by using the branch of Internet service provider (ISP). 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.
