【摘要】：近年来,云计算技术的蓬勃发展为整个IT行业带来了巨大变革。由数以万计的服务器支撑的云计算系统是否能够高效稳定地运行,关键在于这些大数量的服务器能够被有效地组织起来。网络拓扑的合理性对网络的性能的提高和稳定性的加强具有重要的影响,即网络的部分节点或链路在故障或拥挤时也能正常工作。对于电力企业而言,云计算将能够改变电力企业信息化建设的模式。过去都是由单个企业架设自己的电力数据中心,企业与企业之间的沟通交流不多。云计算的利用将会使得整个电力企业数据中心整合到一起,构成一个庞大的数据中心电子云,云计算资源管理平台能够对电力系统数据中心的主机、存储、网络等各类资源进行有效的管理、监控和调度,并通过网络将这些资源作为一种服务提供给用户。传统数据中心网络拓扑构建方式及网络层控制平面的运行机制存在固化性,已经难以满足新形势下日益增长的高性能及高性价比需求,并且无法支持云环境下更加灵活的按带宽租赁数据中心网络的运营方式。本文首先主要分析了云计算在电力企业数据中心研究的可行性与必要性,通过与传统的数据中心作比较,找出其中的不足之处,构建多种网络结构来解决相关问题,从而提高服务器的利用率和拓扑内结点的连通性,获得更大的网络吞吐量,形成低成本高连通的网路拓扑结构。然后阐述了高连通性低造价的网络拓扑结构、Dcell结构、Bcube结构Hyper-Fat-tree Network (HFN)结构,最后引入了一种新的结构即雪花结构。这五种结构对云计算在电力企业数据中心的构建中都起到一定的作用。通过仿真实验验证了雪花结构在传输带宽,吞吐量瓶颈问题和网络延时等数据中心建设问题上都具有一定的优势。
[Abstract]:In recent years, rapid development of cloud computing technology has brought great changes to the entire IT industry. Supported by tens of thousands of servers in cloud computing system is able to operate efficiently and stably, the key lies in the large number of servers can be effectively organized. Plays an important role in strengthening the rationality of the network topology on the performance of the network and improve the the stability of the network is part of a node or link failure or congestion can also work normally. For power enterprises, will be able to change the power enterprise informatization construction mode of cloud computing. In the past are composed of individual companies to set up their own data center power, between the enterprise and enterprise communication using cloud computing is not much. Will the electric power enterprise data center together, constitute a huge data center cloud resource management platform, cloud computing to power All kinds of resources such as hosts, storage, network and other resources in the data center of the force system are effectively managed, monitored and scheduled, and these resources are provided to users as a service through the network.
The traditional data center network topology construction and operation mechanism of network layer control plane existence curing, has been difficult to meet the high performance and high cost of increasing demand under the new situation, and can not support the cloud environment more flexible according to the lease data center network bandwidth operation. This paper mainly analyzes the feasibility of research in cloud computing the electric power enterprise data center and the necessity, by comparing with the traditional data center, find out the deficiency, construct a variety of network structure to solve the problem, so as to improve the connectivity rate and topology node using the server, achieve larger throughput, forming a network topology with low cost and high connectivity. And then describes the highly connected network topology, low cost Dcell structure, Bcube structure of Hyper-Fat-tree Network (HFN) structure, the introduction of A new structure of the snow structure. The five structures in the construction of electric power enterprise data center plays a certain role in cloud computing. Through the simulation experiment of snow structure in the construction of the transmission bandwidth, throughput and delay, the bottleneck problem of data center will have certain advantages.
