Bridge表结构如下： [IMG] 我们先看其中的一项，就是Controller [IMG] OpenFlow配置项：从架构图中我们可以看出，openvwitch的一个bridge可以通过openflow协议，被一个统一的controller管理的。 一旦一个bridge连到一个openflow controller，则flow table就由controller统一管理，如果连接断了： secure： 这个bridge会试图一直连接controller，并不自己建立flow table standalone：一旦bridge三次连不上controller，就自己建立和管理flow table OpenFlow Controller多种多样 [IMG]ubuntu_br上 [IMG] [IMG] [IMG] [IMG] [IMG] 安装floodlight [IMG]clone git://github.com/floodlight/floodlight.git cd floodlight/ ant nohup java -jar target/floodlight.jar > floodlight.log 2>&1 & 设置Controller ovs-vsctl set-controller ubuntu_br tcp:192.168.100.1:6633 [IMG] 访问floodlight的界面 [IMG]API [IMG]API设定规则，只允许Instance01和Instance03之间相互通信 curl -d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow1", "cookie":"0", "priority":"32768", "src-mac":"52:54:00:9b:d5:11","active":"true", "actions":"output=12"}' [IMG]-d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow2", "cookie":"0", "priority":"32768", "src-mac":"52:54:00:9b:d5:77","active":"true", "actions":"output=10"}' [IMG]API清除所有规则 curl [IMG]-d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow1", "cookie":"0", "priority":"32768", "dst-mac":"52:54:00:9b:d5:11","active":"true", "actions":"output=10"}' [IMG]-d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow2", "cookie":"0", "priority":"32768", "dst-mac":"52:54:00:9b:d5:33","active":"true", "actions":"output=11"}' [IMG]-d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow3", "cookie":"0", "priority":"32768", "dst-mac":"52:54:00:9b:d5:77","active":"true", "actions":"output=12"}' [IMG]Instance03，用tcpdump监听Instance02和Instance03，在这个过程中，用REST API将Instance03的包转发给Instance02 curl -d '{"switch": "00:00:2a:96:0e:c7:85:49", "name":"static-flow3", "cookie":"0", "priority":"32768", "dst-mac":"52:54:00:9b:d5:77","active":"true", "actions":"output=11"}' http://16.158.166.150:8080/wm/staticflowentrypusher/json [IMG] |
