| Iperf is a 2 machine test (server/client) that measures maximum TCP and UDP |
| bandwidth performance. The stress test will run for 20 minutes. |
| |
| Arguments to run_test: |
| |
| server_ip - the ip of the server (automatically filled in) |
| client_ip - the ip of the client (automatically filled in) |
| role - specifies either client or server (automatically filled in) |
| udp - [False/True] specifies if a UDP test should be run. Defaults to |
| TCP if unspecified. |
| bidirectional - [False/True] specifies if a bidirectional test should be run. |
| Defaults to False |
| test_time - Specifies test duration of each iteration in seconds. |
| stream_list - A list containing the number of streams to run the test for. If |
| the list is [1,10,100] then the test will run 3 times. If |
| bidirectional is set then there will be the specified number of |
| bidirectional streams. |
