【摘要】：SDN(Software Defined Network,軟件定義網(wǎng)絡(luò))將傳統(tǒng)網(wǎng)絡(luò)中控制與轉(zhuǎn)發(fā)功能進(jìn)行解耦,采用集成了網(wǎng)絡(luò)控制功能的SDN控制器通過開放南向接口對整個網(wǎng)絡(luò)進(jìn)行統(tǒng)一的配置管理,在業(yè)務(wù)應(yīng)用方面,通過北向接口對網(wǎng)絡(luò)應(yīng)用提供可編程能力的支持,SDN技術(shù)的這些優(yōu)勢為替代傳統(tǒng)網(wǎng)絡(luò)提供了很好的方向,為解決新興的電信網(wǎng)絡(luò)業(yè)務(wù)應(yīng)用提供了可能。SDN通過北向接口為應(yīng)用開發(fā)提供可編程接口,使得網(wǎng)絡(luò)業(yè)務(wù)開發(fā)人員不僅可以實現(xiàn)傳統(tǒng)電信應(yīng)用的開發(fā),而且可以實現(xiàn)創(chuàng)新性網(wǎng)絡(luò)應(yīng)用。由于各廠商北向接口開放方式的不同,網(wǎng)絡(luò)應(yīng)用的復(fù)雜多變,業(yè)界目前對北向接口并沒有一個統(tǒng)一的標(biāo)準(zhǔn)。更好的設(shè)計北向接口,不僅有利于SDN網(wǎng)絡(luò)技術(shù)的本身的發(fā)展,更決定了未來網(wǎng)絡(luò)應(yīng)用的發(fā)展速度。論文通過對SDN在電信網(wǎng)中的應(yīng)用及控制功能的研究,對SDN控制器北向接口的業(yè)務(wù)需求進(jìn)行了分析,對需求進(jìn)行了提煉。基于SDN控制器北向接口服務(wù)功能的抽象級別,設(shè)計了一種基于層次化架構(gòu)的北向接口模型,將北向接口層次模型分為基本級、網(wǎng)絡(luò)級、業(yè)務(wù)級三層,通過上層調(diào)用下層API,實現(xiàn)更高級別的API。論文采用REST(Representational State Transfer,表述性狀態(tài)轉(zhuǎn)移)相關(guān)技術(shù)進(jìn)行開發(fā),實現(xiàn)了一種功能可擴展的SDN北向接口;針對流媒體等對QoS(Quality of Service,服務(wù)質(zhì)量保證)具有較大需求的電信網(wǎng)絡(luò)業(yè)務(wù)應(yīng)用,設(shè)計并實現(xiàn)了具有QoS參數(shù)的SDN北向接口,包括鏈路網(wǎng)絡(luò)參數(shù)的獲取,如丟包、時延等,還可以對用戶流帶寬的管理。并基于QoS北向接口設(shè)計了一個業(yè)務(wù)應(yīng)用服務(wù)層,使得網(wǎng)絡(luò)管理人員可以實時獲取網(wǎng)絡(luò)中服務(wù)質(zhì)量參數(shù),進(jìn)行網(wǎng)絡(luò)控制。測試結(jié)果表明,論文設(shè)計的層次化北向接口具有一定的靈活性和可擴展性,能夠?qū)﹄娦啪W(wǎng)的QoS業(yè)務(wù)應(yīng)用提供一定的支持。
[Abstract]:SDN (Software Defined Network, software defined network) decouples the control and forwarding function of the traditional network, and uses the SDN controller with integrated network control function to manage the whole network through the open South interface. In the business application, it provides the programmability of the network application through the north interface. The advantages of SDN technology provide a good direction to replace the traditional network, and provide the possible.SDN through the north interface to provide a programmable interface for the application and development of the new telecom network services, so that the network business developers can not only realize the development of the traditional electrical letter application, but also realize the innovative network. Because of the different open ways of each vendor's north interface and the complex and changeable network application, the industry has not a unified standard for the north interface. Better design of the north interface is not only beneficial to the development of SDN network technology itself, but also the development speed of the network in the future. The paper through the SDN in the telecommunication network The application and control function of the SDN controller are analyzed and the demand of the north interface is analyzed and the demand is refined. Based on the abstract level of the north interface service function of the SDN controller, a north interface model based on the hierarchical architecture is designed, which divides the North connection level model into the basic level, the network level, and the business level three. Layer, through the upper layer call lower API, to achieve a higher level API. paper using REST (Representational State Transfer, expressive state transfer) related technologies to develop a functional scalable SDN north interface; a telecommunication network with large demand for QoS (Quality of Service, quality of service) and so on. Business applications, design and implement a SDN north interface with QoS parameters, including link network parameters, such as packet loss, delay, and the management of user flow bandwidth. Based on the QoS north interface, a business application service layer is designed to enable network managers to obtain real-time network service quality parameters and network. The test results show that the hierarchical north direction interface designed by the paper has a certain flexibility and extensibility, and can provide some support to the QoS service application of the telecommunication network.
