【摘要】：近年來(lái),云計(jì)算技術(shù)的蓬勃發(fā)展為整個(gè)IT行業(yè)帶來(lái)了巨大變革。由數(shù)以萬(wàn)計(jì)的服務(wù)器支撐的云計(jì)算系統(tǒng)是否能夠高效穩(wěn)定地運(yùn)行,關(guān)鍵在于這些大數(shù)量的服務(wù)器能夠被有效地組織起來(lái)。網(wǎng)絡(luò)拓?fù)涞暮侠硇詫?duì)網(wǎng)絡(luò)的性能的提高和穩(wěn)定性的加強(qiáng)具有重要的影響,即網(wǎng)絡(luò)的部分節(jié)點(diǎn)或鏈路在故障或擁擠時(shí)也能正常工作。對(duì)于電力企業(yè)而言,云計(jì)算將能夠改變電力企業(yè)信息化建設(shè)的模式。過(guò)去都是由單個(gè)企業(yè)架設(shè)自己的電力數(shù)據(jù)中心,企業(yè)與企業(yè)之間的溝通交流不多。云計(jì)算的利用將會(huì)使得整個(gè)電力企業(yè)數(shù)據(jù)中心整合到一起,構(gòu)成一個(gè)龐大的數(shù)據(jù)中心電子云,云計(jì)算資源管理平臺(tái)能夠?qū)﹄娏ο到y(tǒng)數(shù)據(jù)中心的主機(jī)、存儲(chǔ)、網(wǎng)絡(luò)等各類資源進(jìn)行有效的管理、監(jiān)控和調(diào)度,并通過(guò)網(wǎng)絡(luò)將這些資源作為一種服務(wù)提供給用戶。 傳統(tǒng)數(shù)據(jù)中心網(wǎng)絡(luò)拓?fù)錁?gòu)建方式及網(wǎng)絡(luò)層控制平面的運(yùn)行機(jī)制存在固化性,已經(jīng)難以滿足新形勢(shì)下日益增長(zhǎng)的高性能及高性價(jià)比需求,并且無(wú)法支持云環(huán)境下更加靈活的按帶寬租賃數(shù)據(jù)中心網(wǎng)絡(luò)的運(yùn)營(yíng)方式。本文首先主要分析了云計(jì)算在電力企業(yè)數(shù)據(jù)中心研究的可行性與必要性,通過(guò)與傳統(tǒng)的數(shù)據(jù)中心作比較,找出其中的不足之處,構(gòu)建多種網(wǎng)絡(luò)結(jié)構(gòu)來(lái)解決相關(guān)問(wèn)題,從而提高服務(wù)器的利用率和拓?fù)鋬?nèi)結(jié)點(diǎn)的連通性,獲得更大的網(wǎng)絡(luò)吞吐量,形成低成本高連通的網(wǎng)路拓?fù)浣Y(jié)構(gòu)。然后闡述了高連通性低造價(jià)的網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)、Dcell結(jié)構(gòu)、Bcube結(jié)構(gòu)Hyper-Fat-tree Network (HFN)結(jié)構(gòu),最后引入了一種新的結(jié)構(gòu)即雪花結(jié)構(gòu)。這五種結(jié)構(gòu)對(duì)云計(jì)算在電力企業(yè)數(shù)據(jù)中心的構(gòu)建中都起到一定的作用。通過(guò)仿真實(shí)驗(yàn)驗(yàn)證了雪花結(jié)構(gòu)在傳輸帶寬,吞吐量瓶頸問(wèn)題和網(wǎng)絡(luò)延時(shí)等數(shù)據(jù)中心建設(shè)問(wèn)題上都具有一定的優(yōu)勢(shì)。
[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.
