我想将交换机中的链接参数添加到遥控器(泛光灯),我该怎么办?我的意思是我想在交换机与控制器之间指定链路带宽,链路延迟..
是实现双向链接的正确方法吗?
net.addLink('s1','s2', bw=43)
net.addLink('s2','s1', bw=35)
我正在使用此自定义拓扑

如果您的代码是
net.addLink(' s1',' s2',bw = 43)
net.addLink(' s2',' s1',bw = 35)
您将获得两个带宽不同的链接。 你可以在mininet中使用命令网来检查网络连接,你会发现两者都是' s1'和' s2'将为2个链接打开2个端口,如:
s1 lo:s1-eth1:s2-eth1 s1-eth2:s2-eth2
s2 lo:s2-eth1:s1-eth1 s2-eth2:s1-eth2
