【摘要】：隨著互聯(lián)網(wǎng)技術(shù)的發(fā)展,尤其是數(shù)據(jù)中心、云計(jì)算、移動(dòng)互聯(lián)網(wǎng)等技術(shù)的推動(dòng),用戶的需求越來(lái)越復(fù)雜,業(yè)務(wù)更新越來(lái)越快,傳統(tǒng)的互聯(lián)網(wǎng)架構(gòu)表現(xiàn)出越來(lái)越多的不適應(yīng)性。軟件定義網(wǎng)絡(luò)(Software-Defined Networking, SDN)基于將網(wǎng)絡(luò)設(shè)備的控制面與轉(zhuǎn)發(fā)面分離,并且形成統(tǒng)一的控制平面的思想,無(wú)疑使其成為解決現(xiàn)有問(wèn)題,構(gòu)建下一代互聯(lián)網(wǎng)的關(guān)鍵技術(shù)�？刂破髯鳛镾DN的核心組成部分,作為聯(lián)系應(yīng)用層和數(shù)據(jù)轉(zhuǎn)發(fā)層的橋梁,其功能的實(shí)現(xiàn)方式和完善程度對(duì)SDN技術(shù)的發(fā)展有重大影響。與控制器在南向接口已有OpenFlow協(xié)議作為標(biāo)準(zhǔn)不同,控制器在面向北向的支持技術(shù)上還沒(méi)有統(tǒng)一定論。因此,緊隨業(yè)界和學(xué)術(shù)界的研究步伐,本人主要進(jìn)行了如下工作： (1)通過(guò)對(duì)SDN邏輯架構(gòu)、底層OpenFlow交換機(jī)的規(guī)范及OpenFlow協(xié)議的研究,對(duì)整個(gè)SDN網(wǎng)絡(luò)體系結(jié)構(gòu)有了宏觀的認(rèn)識(shí)。 (2)結(jié)合開(kāi)源控制器Floodlight,對(duì)SDN中的控制器的架構(gòu)、功能模塊和內(nèi)部實(shí)現(xiàn)方式進(jìn)行了研究和分析,對(duì)實(shí)現(xiàn)控制器面向北向的技術(shù)創(chuàng)新奠定了基礎(chǔ)。 (3)通過(guò)對(duì)應(yīng)用層需求和常見(jiàn)控制器以REST API方式實(shí)現(xiàn)北向接口局限性的分析,提出了以專為SDN業(yè)務(wù)建模而定義的OpenNML語(yǔ)言作為控制器北向支持技術(shù)的解決方案。 (4)在前述研究成果的指導(dǎo)下,在Floodlight控制器上進(jìn)行二次開(kāi)發(fā),設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)基于OpenNML語(yǔ)言的SDN控制器。該控制器不同于目前的控制器僅提供特定的API以滿足特定的業(yè)務(wù)需求,而是能夠以一種通用且靈活的方式供不同應(yīng)用場(chǎng)景下的用戶進(jìn)行統(tǒng)一建模,推動(dòng)了控制器面向北向的標(biāo)準(zhǔn)化進(jìn)程。最后本文設(shè)計(jì)了一個(gè)原型系統(tǒng),對(duì)命名為Prislight的控制器實(shí)例進(jìn)行了功能驗(yàn)證實(shí)驗(yàn),實(shí)驗(yàn)結(jié)果表明本文的控制器方案具有可行性和實(shí)用性。
[Abstract]:With the development of Internet technology, especially the promotion of data center, cloud computing, mobile Internet and other technologies, the needs of users are becoming more and more complex, and business renewal is becoming faster and faster. The traditional Internet architecture shows more and more inadaptability. The software defines the network Software-Defined Network (SDN) based on the idea of separating the control surface of the network device from the forwarding surface and forming a unified control plane, which undoubtedly makes it a solution to the existing problems. Controller, as the core component of SDN, acts as a bridge between application layer and data forwarding layer. The realization and perfection of the function have a great influence on the development of SDN technology. Unlike the OpenFlow protocol in the south interface, the support technology of the controller facing to the north has not been unified. Following the pace of research in the industry and academia, I have mainly carried out the following work:. 1) based on the research of SDN logic architecture, the specification of bottom OpenFlow switch and OpenFlow protocol, the whole SDN network architecture is understood macroscopically. Based on the open source controller Floodlight, the architecture, function module and internal implementation of controller in SDN are studied and analyzed, which lays a foundation for the northward innovation of controller. 3) based on the analysis of the requirement of application layer and the limitation of the common controller to realize the northward interface by REST API, this paper puts forward the solution of using OpenNML language, which is defined for SDN business modeling, as the northward support technology of the controller. 4) under the guidance of the above research results, a SDN controller based on OpenNML language is designed and implemented on the Floodlight controller. The controller is different from the current controller in providing only specific API to meet the specific business requirements. Instead, it can be used in a general and flexible way for users in different application scenarios to build a unified model, which promotes the northward standardization process of the controller. Finally, a prototype system is designed in this paper. The function verification experiment of the controller named Prislight is carried out. The experimental results show that the controller scheme in this paper is feasible and practical.
