WebRunning iperf in Mininet This output tells us that the link between h1 and h8 has a maximum capacity of 69Gbps ( nice ). See the iperf guide here! Stage 5: Multiple Topologies Sometimes you might need quick access to multiple topologies. Luckily, you can very easily define multiple topologies in mn topology files. WebTo implement the bandwidth limit, Mininet then takes care of creating the virtual-Ethernet links with a rate constraint. To implement the delay, Mininet uses a queuing hierarchy (19.7 Hierarchical Queuing). The hierarchy is managed by the tc (traffic control) command, part of the LARTCsystem. gohn and stambaughWeb第一种，在创建的网络拓扑的时候，使用 --link 这个选项： sudo mn --topo linear, 10 --link tc,bw= 10 这一条命令，就可以创建出一个拓扑是线性的，并且每一条连接都是10m的带 … gohn and stambaugh york
