【摘要】：OVS(open vSwitch)作為一款開源的SDN軟件交換機,得到了廣泛關(guān)注。但在復雜多變的網(wǎng)絡環(huán)境下,易出現(xiàn)數(shù)據(jù)層失去控制器控制和流表項學習老化等故障問題,嚴重制約了SDN性能。針對以上問題,研究設計了OVS的編程擴展技術(shù)架構(gòu),包含鏈接狀態(tài)處理、故障感知、二三層自學習轉(zhuǎn)發(fā)等核心功能的擴展,使OVS實現(xiàn)自動快速恢復、流表表項及時更新,保障了SDN吞吐量,從而減小了控制器失聯(lián)對通信的影響,增強了SDN的穩(wěn)定性和可靠性。
[Abstract]:OVS (open vSwitch) as an open source SDN software switch, has been widely concerned. However, in the complex and changeable network environment, the data layer loss of controller control and the aging of flow table items are easy to occur, which seriously restricts the performance of SDN. Aiming at the above problems, this paper studies and designs the technical framework of programming extension of OVS, including the extension of core functions such as link state processing, fault sensing, self-learning and forwarding of layer two and three, so that OVS can realize automatic and fast recovery, and the flow table items can be updated in time. The throughput of SDN is guaranteed, and the influence of controller disconnection on communication is reduced, and the stability and reliability of SDN are enhanced.
