iPerf is a point-to-point network tool for active measurements of throughput between two servers in both directions. We need to install iPerf tool on our 2 physical servers with command sudo apt-get install iperf3. We will test the bandwidth speed from the origin servers (iPerf client servers) in fact HCoS#1-A, HCoS#1-C and HCoS#2-D to the destination server (iPerf listening server) in fact HCoS#2-B. All these mentioned servers are logical servers from iPerf perspective and because of nature of iPerf we need to use different TCP port for testing when we send traffic from iPerf clinets to iPerf server in order to get all results on servers.
