【摘要】:網(wǎng)絡(luò)業(yè)務(wù)的不斷發(fā)展,對網(wǎng)絡(luò)性能要求越來越高;傳統(tǒng)的網(wǎng)絡(luò)架構(gòu)略顯臃腫,難以應(yīng)對日益繁雜的業(yè)務(wù)需求。而SDN概念的提出打破了這種尷尬的局面,其核心思想是將網(wǎng)絡(luò)數(shù)據(jù)的轉(zhuǎn)發(fā)與控制充分的分離,并且解放轉(zhuǎn)發(fā)設(shè)備,通過軟件控制器實現(xiàn)對網(wǎng)絡(luò)的集中管控。這種新型網(wǎng)絡(luò)架構(gòu)所帶來的好處是將網(wǎng)絡(luò)充分扁平化,通過集中控制可以掌握全網(wǎng)信息做出更全面且更有利的決策。但是站在運營商的角度,要實現(xiàn)將現(xiàn)有網(wǎng)絡(luò)設(shè)備全部替換為SDN設(shè)備需要的費用與成本是其不可接收的。因此,綜合了SDN的先進理念與現(xiàn)有PTN網(wǎng)絡(luò)而產(chǎn)生的S-PTN網(wǎng)絡(luò)成為了運營商的新寵。S-PTN在原有EMS管理平臺上引進了SDN控制器來管控全網(wǎng),同時支持包括Open Flow、Qx等多種南向協(xié)議,大大擴展了原有PTN網(wǎng)絡(luò)的靈活性。由于控制器可以管控全網(wǎng),本文結(jié)合著某通信企業(yè)的合作項目在控制器中實現(xiàn)了一種參考網(wǎng)絡(luò)實時狀態(tài)的轉(zhuǎn)發(fā)策略系統(tǒng)。為了完成該系統(tǒng),本文首先對S-PTN技術(shù)體系、OpenFlow相關(guān)技術(shù)、OpenDaylight控制器、Mininet網(wǎng)絡(luò)仿真平臺進行了詳細描述,并對其中的關(guān)鍵技術(shù)進行了深入分析。接下來描述了參考網(wǎng)絡(luò)實時狀態(tài)的轉(zhuǎn)發(fā)策略系統(tǒng)的設(shè)計過程,包括網(wǎng)絡(luò)測量模塊、轉(zhuǎn)發(fā)策略模塊以及北向接口的設(shè)計,并分模塊介紹了各個部分的功能。除此之外,本文還深入研究了遺傳算法與蟻群算法在OpenFlow流尋路中的應(yīng)用,提出了一種遺傳算法與蟻群算法的動態(tài)融合方法來實現(xiàn)數(shù)據(jù)流轉(zhuǎn)發(fā)的策略。進而,以控制器插件的形式對參考網(wǎng)絡(luò)實時狀態(tài)的轉(zhuǎn)發(fā)策略系統(tǒng)進行了實現(xiàn)。然后,本文通過Mininet仿真平臺搭建網(wǎng)絡(luò)環(huán)境,基于不同的網(wǎng)絡(luò)拓撲驗證了參考網(wǎng)絡(luò)實時狀態(tài)的轉(zhuǎn)發(fā)策略系統(tǒng)的有效性,并通過RESTClient工具對北向接口進行了測試,對實驗和測試的結(jié)果進行了分析與總結(jié)。最后,本文對所完成的工作進行了總結(jié),提出了現(xiàn)有工作中的不足以及后續(xù)研究的方向。
[Abstract]:With the continuous development of network services, the network performance requirements are becoming more and more high, and the traditional network architecture is slightly bloated, which makes it difficult to cope with the increasingly complex business requirements. The concept of SDN breaks this awkward situation. Its core idea is to separate the network data from the control sufficiently, and to liberate the forwarding equipment and realize the centralized control of the network through the software controller. The advantage of this new network architecture is that the network is flattened and the information of the whole network can be grasped by centralized control to make more comprehensive and beneficial decisions. But from the point of view of operators, the cost and cost of replacing all existing network devices with SDN devices is unacceptable. Therefore, combining the advanced idea of SDN with the existing PTN network, the S-PTN network has become the carrier's new favorite. S-PTN has introduced the SDN controller on the original EMS management platform to control the whole network, and also supports a variety of southward protocols, including Open flow QX and so on. The flexibility of the original PTN network is greatly expanded. Because the controller can control the whole network, this paper realizes a kind of forwarding policy system with reference network real-time state in the controller combined with the cooperative project of a communication enterprise. In order to complete the system, this paper first describes the S-PTN technology system and the related technology of OpenDaylight controller / Mininet network simulation platform in detail, and analyzes the key technologies in detail. Then the design process of the forwarding policy system with reference to the real-time state of the network is described, including the network measurement module, the forwarding policy module and the design of the northward interface, and the functions of each part are introduced in each module. In addition, this paper studies the application of genetic algorithm and ant colony algorithm in OpenFlow flow routing, and proposes a dynamic fusion method of genetic algorithm and ant colony algorithm to realize data stream forwarding. Furthermore, the forwarding policy system of reference network real-time state is implemented in the form of controller plug-in. Then, the Mininet simulation platform is used to build the network environment, and based on different network topologies, the validity of the forwarding strategy system of reference network real-time state is verified, and the northward interface is tested by RESTClient tool. The results of experiments and tests are analyzed and summarized. Finally, this paper summarizes the work done, puts forward the shortcomings of the existing work and the direction of follow-up research.
