【摘要】：近年來,隨著云計算技術(shù)的廣泛應(yīng)用,數(shù)據(jù)中心承載的服務(wù)器越來越多,網(wǎng)絡(luò)規(guī)模不斷擴大。為此,研究人員提出了多種新型網(wǎng)絡(luò)結(jié)構(gòu)用來支持更大規(guī)模的數(shù)據(jù)中心網(wǎng)絡(luò)。隨著網(wǎng)絡(luò)規(guī)模的擴大,數(shù)據(jù)中心網(wǎng)絡(luò)在路由收斂速度、多路徑路由、路由效率等一系列路由問題上遇到挑戰(zhàn)。 為了解決上述各種路由問題,本文采用計算路由的思想,提出一種面向數(shù)據(jù)中心網(wǎng)絡(luò)的迂回路由方法。該路由方法利用數(shù)據(jù)中心網(wǎng)絡(luò)拓撲的規(guī)則性計算路由,并采用迂回路由的方式解決網(wǎng)絡(luò)中的鏈路和節(jié)點故障問題。為了提高該路由方法的通用性,本文提出一種適用于該迂回路由方法的通用路由框架�；谠摽蚣�,可以方便地把該路由方法應(yīng)用到各種不同的網(wǎng)絡(luò)拓撲結(jié)構(gòu)中。 本文以BCube2網(wǎng)絡(luò)架構(gòu)作為范例,詳細闡述了如何以通用路由框架為基礎(chǔ)設(shè)計和實現(xiàn)BCube2網(wǎng)絡(luò)的迂回路由算法(BCube2-CR)。在該部分,本文通過實際例子詳細介紹了BCube2-CR路由的地址編碼方法、基礎(chǔ)路由表和迂回路由表的構(gòu)造過程以及迂回路由決策過程。參考上述過程,可以設(shè)計開發(fā)其他不同數(shù)據(jù)中心網(wǎng)絡(luò)拓撲結(jié)構(gòu)的迂回路由算法。 為了驗證BCube2-CR迂回路由算法的可行性和性能,本課題采用OPNET網(wǎng)絡(luò)仿真軟件作為實驗平臺,對BCube2網(wǎng)絡(luò)的迂回路由算法進行了仿真實驗,并結(jié)合實驗結(jié)果對BCube2網(wǎng)絡(luò)迂回路由算法的性能進行驗證分析。
[Abstract]:In recent years, with the extensive application of cloud computing technology, there are more and more servers in data center, and the scale of network is expanding. To this end, researchers have proposed a variety of new networks to support larger-scale data center networks. With the expansion of network scale, data center networks face challenges in routing convergence speed, multi-path routing, routing efficiency and so on. In order to solve all kinds of routing problems mentioned above, this paper proposes an alternate routing method for data center networks based on the idea of computational routing. The routing method uses the regularity of the data center network topology to calculate the routing and solves the problem of link and node failure in the network by the way of circuitous routing. In order to improve the generality of the routing method, a general routing framework is proposed in this paper. Based on this framework, the routing method can be easily applied to various network topologies. Taking the BCube2 network architecture as an example, this paper describes in detail how to design and implement the roundabout routing algorithm (BCube2-CR) of BCube2 network based on the general routing framework. In this part, the address coding method of BCube2-CR routing, the construction process of basic routing table and alternate loop routing table and the decision-making process of alternate loop routing are introduced in detail by practical examples. Referring to the above process, we can design and develop alternate routing algorithms for other data center network topologies. In order to verify the feasibility and performance of the BCube2-CR roundabout routing algorithm, the OPNET network simulation software is used as the experimental platform to simulate the roundabout routing algorithm of the BCube2 network. Combined with the experimental results, the performance of the roundabout routing algorithm in BCube2 network is verified and analyzed.
