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

As an open source SDN software switch

open vSwitch (OVS) has been widespread concerned.But in complex and changeable network environment

data layer loses control of controller and flow table entry learning aging appears easily and the performance of SDN is seriously hampered.To solve the problems

the programming extension technology architecture of OVS was designed

including link state processing

fault perception

two three-tier self-learning forwarding and other expansion of core functions

so that OVS could recover automatic and rapidly

flow table entries could update in time

throughput of SDN was guaranteed

thereby the influence of control-ler loss control for communication was reduced

SDN stability and reliability was enhanced.
