【摘要】：OVS(open vSwitch)作为一款开源的SDN软件交换机,得到了广泛关注。但在复杂多变的网络环境下,易出现数据层失去控制器控制和流表项学习老化等故障问题,严重制约了SDN性能。针对以上问题,研究设计了OVS的编程扩展技术架构,包含链接状态处理、故障感知、二三层自学习转发等核心功能的扩展,使OVS实现自动快速恢复、流表表项及时更新,保障了SDN吞吐量,从而减小了控制器失联对通信的影响,增强了SDN的稳定性和可靠性。
[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.
