【摘要】：近年來,隨著云計算技術(shù)的廣泛應(yīng)用,數(shù)據(jù)中心網(wǎng)絡(luò)的規(guī)模不斷擴(kuò)大。數(shù)據(jù)中心網(wǎng)絡(luò)的路由方法作為影響數(shù)據(jù)中心各項性能指標(biāo)的重要因素之一,一直是相關(guān)研究中的熱點問題。目前,數(shù)據(jù)中心網(wǎng)絡(luò)在路由效率、多路徑路由、路由收斂速度等一系列路由問題上遇到了很大的挑戰(zhàn)。首先,本文提出了一種新的轉(zhuǎn)發(fā)地址,稱為PA(Port Address),該轉(zhuǎn)發(fā)地址以端口編號為基礎(chǔ)進(jìn)行編碼。然后利用PA的特性,采用"源路由"思想,設(shè)計了一種面向數(shù)據(jù)中心網(wǎng)絡(luò)的基于端口編址的路由方法(Port Address Source Routing,PASR)。該路由方法主要利用PA編址的特性和數(shù)據(jù)中心網(wǎng)絡(luò)拓?fù)涞囊?guī)則性由源端計算路由路徑以完成節(jié)點間的通信。為了提高該路由方法的通用性,本文提出了一種適用于PASR路由方法的通用框架。基于該框架,可以方便的把PASR路由方法應(yīng)用到各種不同的網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)中。其次,本文以FaceBook下一代數(shù)據(jù)中心網(wǎng)絡(luò)架構(gòu)作為范例,詳細(xì)闡述了以通用路由框架為基礎(chǔ)如何設(shè)計和實現(xiàn)FaceBook下一代數(shù)據(jù)中心網(wǎng)絡(luò)的PASR路由方法(FaceBook-PASR)。在該部分,論文通過實際例子詳細(xì)介紹了 FaceBook-PASR路由的地址編碼方式、基本PASR路由算法和E2E(End-To-End)容錯算法的實現(xiàn)。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?fù)浣Y(jié)構(gòu)的PASR路由方法。最后,為了驗證FaceBook-PASR路由方法的可行性和性能,本文采用OMNeT++網(wǎng)絡(luò)仿真軟件作為實驗平臺,對FaceBook下一代數(shù)據(jù)中心網(wǎng)絡(luò)的PASR路由方法進(jìn)行了仿真實驗,并結(jié)合實驗結(jié)果對PASR路由方法的可行性和性能進(jìn)行了驗證分析。實驗表明,PASR路由方法提高了網(wǎng)絡(luò)吞吐量,降低了端到端時延,可以適應(yīng)各種通信模式。
[Abstract]:In recent years, with the wide application of cloud computing technology, the scale of data center network is expanding. The routing method of data center network is one of the important factors that affect the performance of data center. At present, the data center network has encountered great challenges in routing efficiency, multipath routing, routing convergence speed and so on. Firstly, a new forwarding address is proposed in this paper. Called PA(Port address address, the forwarding address is encoded on the basis of port number. In this paper, a port addressing based routing method for data center network is designed. This routing method mainly utilizes PA addressing property and the rule of data center network topology to calculate routing path from source side to complete section. Communication between points. In order to improve the versatility of the routing method, This paper presents a general framework for PASR routing methods. Based on this framework, PASR routing methods can be easily applied to various network topologies. Secondly, this paper takes the next generation data center network architecture of FaceBook as an example. This paper describes in detail how to design and implement the PASR routing method of the next generation data center network of FaceBook based on the general routing framework. In this part, the address encoding method of FaceBook-PASR routing is introduced in detail through practical examples. The implementation of the basic PASR routing algorithm and the E2EN-End-To-End) fault-tolerant algorithm. Referring to the above process, we can design and develop the PASR routing method for other different data center network topologies. Finally, in order to verify the feasibility and performance of the FaceBook-PASR routing method, In this paper, the OMNeT network simulation software is used as the experimental platform to simulate the PASR routing method in the next generation data center network of FaceBook. Based on the experimental results, the feasibility and performance of the PASR routing method are verified and analyzed. The experimental results show that the PASR routing method can improve the network throughput, reduce the end-to-end delay, and adapt to various communication modes.
