OVS概览 1.经典架构 OVS可以划分为三大块:管理面、数据面和控制面数据面就是以用户态的ovs-vswitchd和内核态的datapath为主的转发模块,以及与之相关联的数据库模块ovsdb-server,控制面主要是由ovs-ofctl模块负…

datapath内核模块,根据流表匹配结果做相应处理 3.OVS代码架构 vswitchd是ovs主要的用户态程序,他从ovsdb-server读取配置并发送到ofproto层,也从ofproto读取特定的状态和统计信息并发送到数据库。 ofproto是openflow的接口层,负责和Openflow controller通信并通过ofproto_class与ofprotot provider底层交互 ...

In this mode,?ovs?vswitchd?causes the datapath to act like an ordinary MAC-learning switch.?ovs?vswitchd?will continue to retry connecting to the controller in the background and, when the connection succeeds, it discontinues its standalone behavior. If this option is set to?secure,?ovs?
