As the figure shows below, we create the same four-node topology by loading `4node-v3.rspec` in Flack, and create two more VMs as a client and a server, and add two virtual links. For client and server, we select regular `Ubuntu 12.04` OS in the node information, so we need to install `iperf` separately. In this example, there are only two hosts need iperf installed, so one option is to login to each host, and manually install it by running |
