【摘要】：隨著國(guó)家電網(wǎng)“十二五”及“十三五”計(jì)劃期間先后宣布和實(shí)施“堅(jiān)強(qiáng)智能電網(wǎng)計(jì)劃”、“三大五集重要舉措”和“能源互聯(lián)網(wǎng)戰(zhàn)略”,電力數(shù)據(jù)中心網(wǎng)絡(luò)起到極其重要支撐的作用。與此同時(shí)為了確保相關(guān)支撐信息系統(tǒng)能夠穩(wěn)定運(yùn)行,這也對(duì)電力系統(tǒng)數(shù)據(jù)中心網(wǎng)絡(luò)的通信能力有了更加嚴(yán)格的要求,尤其是當(dāng)前云計(jì)算、大數(shù)據(jù)等技術(shù)在電力系統(tǒng)中的應(yīng)用方興未艾,數(shù)據(jù)流量劇增,從而導(dǎo)致了電力數(shù)據(jù)中心網(wǎng)絡(luò)中規(guī)模不斷擴(kuò)大以及給其帶來巨大壓力,因此,現(xiàn)存的電力網(wǎng)絡(luò)體系結(jié)構(gòu)中目前很難滿足未來快速發(fā)展的需求。網(wǎng)絡(luò)QoS能夠給網(wǎng)絡(luò)帶來高效的運(yùn)行、提升網(wǎng)絡(luò)效率和降低網(wǎng)絡(luò)成本開銷。因此,如何在電力數(shù)據(jù)中心網(wǎng)絡(luò)中實(shí)現(xiàn)特定的QoS和網(wǎng)絡(luò)路由策略成為研究熱點(diǎn)。SDN采用OpenFlow協(xié)議是一種基于多域網(wǎng)包頭描述的流轉(zhuǎn)發(fā)機(jī)制的控制/轉(zhuǎn)發(fā)分離的網(wǎng)絡(luò),真正可以成為解決電力數(shù)據(jù)中心網(wǎng)絡(luò)路由問題的一項(xiàng)關(guān)鍵技術(shù)。本文首先對(duì)電力企業(yè)數(shù)據(jù)中心網(wǎng)絡(luò)的現(xiàn)狀和面對(duì)的問題闡述和分析。給出了SDN技術(shù)和OpenFlow協(xié)議出現(xiàn)的背景,闡述了SDN的基本思想和OpenFlow技術(shù),細(xì)致的描述了OpenFlow交換機(jī)的大致構(gòu)成,OpenFlow協(xié)議的發(fā)展歷程、消息類型和消息的基本數(shù)據(jù)機(jī)構(gòu),簡(jiǎn)介了幾種通用的SDN控制器和Floodlight控制器的主要模塊。分析基于SDN技術(shù)用于電力數(shù)據(jù)中心網(wǎng)絡(luò)存在的問題解決的可行性。通過對(duì)基于SDN的電力數(shù)據(jù)中心路由策略研究,利用SDN提出的控制層與數(shù)據(jù)層分離的思想,提出了一種基于OpenFlow的QoS-ensure流量控制方法,該方法主要由QoS流量控制策略框架來實(shí)現(xiàn),主要模塊包括:QoS路由管理、路由引擎、QoS控制、數(shù)據(jù)監(jiān)測(cè)、故障監(jiān)測(cè)、鏈路發(fā)現(xiàn)等�？蚣苤袛�(shù)據(jù)監(jiān)視、鏈路發(fā)現(xiàn)和故障監(jiān)測(cè)模塊來收集OpenFlow交換機(jī)中相應(yīng)的信息。收集到的信息傳送給路由引擎和QoS控制模塊,QoS控制模塊將分析的QoS信息發(fā)送給路由引擎模塊,路由引擎模塊根據(jù)自己路由算法決定路徑選擇。路由算法采取了優(yōu)化的智能啟發(fā)式蟻群算法方式來進(jìn)行鏈路的選擇。結(jié)尾通過使用Mininet網(wǎng)絡(luò)仿真平臺(tái)和Floodlight控制器對(duì)提出的路由策略進(jìn)行仿真實(shí)驗(yàn)和得出相關(guān)數(shù)據(jù),最后和ECMP算法進(jìn)行性能比較,證實(shí)了本文提出的路由策略的有效性和可行性。
[Abstract]:With the State Grid's 12th Five-Year Plan and the 13th Five-Year Plan announced and implemented successively during the "strong Smart Grid Plan," three major five major initiatives "and" Energy Internet Strategy, " Power data center network plays an extremely important role in supporting. At the same time, in order to ensure the stable operation of the related supporting information systems, there are more stringent requirements for the communication capability of the power system data center network, especially in the current cloud computing. The application of big data and other technologies in the power system is in the ascendant, and the data flow is increasing dramatically, which leads to the continuous expansion of the scale of the power data center network and brings great pressure to it, so, The current power network architecture is difficult to meet the needs of rapid development in the future. Network QoS can bring high efficiency to network, improve network efficiency and reduce network cost. Therefore, how to implement specific QoS and network routing strategy in power data center network has become a research hotspot. OpenFlow protocol is a separate control / forwarding network based on the flow transmission mechanism described by the packet header of multi-domain network. It can be a key technology to solve the routing problem of power data center network. In this paper, the current situation and problems of electric power enterprise data center network are described and analyzed. This paper gives the background of SDN technology and OpenFlow protocol, expounds the basic idea of SDN and OpenFlow technology, and describes in detail the development course, message type and basic data organization of OpenFlow switch. The main modules of several general SDN controllers and Floodlight controllers are introduced. The feasibility of using SDN technology to solve the problems in power data center network is analyzed. By studying the routing strategy of power data center based on SDN and using the idea of separating control layer and data layer proposed by SDN, a QoS-ensure flow control method based on OpenFlow is proposed. This method is mainly implemented by QoS traffic control strategy framework. The main modules include: QoS routing management, routing engine QoS control, data monitoring, fault monitoring, link discovery and so on. The data monitoring, link discovery and fault monitoring modules in the framework collect the corresponding information in the OpenFlow switch. The collected information is transmitted to the routing engine and the QoS control module, which sends the analyzed QoS information to the routing engine module, which determines the path selection according to its own routing algorithm. The routing algorithm adopts the optimized intelligent heuristic ant colony algorithm to select the link. In the end, the proposed routing strategy is simulated by using Mininet network simulation platform and Floodlight controller, and the relevant data are obtained. Finally, the effectiveness and feasibility of the proposed routing strategy are verified by comparing the performance of the proposed routing strategy with the ECMP algorithm.
