controller会根据网络情况给ovs下发流表,或者命令ovs-ofctl,属于Userspace的流表(ofproto classifier)。 当报文来的时候会先提取key值,然后在Datapath的流表(EMC或者microflow)进行查找匹配,查找到之后会进行action操作 如果没有查找到,就会转而继续查找Datapath的流表(也叫dpcls、TSS classifier、megaflow)。
一、OVS简介Openvswitch是一个优秀的开源软件交换机,支持主流的交换机功能,比如二层交换、网络隔离、QoS、流量监控等,而其最大的特点就是支持openflow,openflow定义了灵活...openflow交换机(采用openflow 协议) 接下来实验中主要涉及的模块为ovs-vsctl以及ovs-ofctl。 三、安装OVS1、环境:ubuntu18.04 LTS Open ...
