|test purpose  | To evaluate the IaaS network performance with regards to     |
|              | flows and throughput, such as if and how different amounts   |
|              | of packet sizes and flows matter for the throughput between  |
|              | VMs on different compute blades. Typically e.g. the          |
|              | performance of a vSwitch                                     |
|              | depends on the number of flows running through it. Also      |
|              | performance of other equipment or entities can depend        |
|              | on the number of flows or the packet sizes used.             |
|              | The purpose is also to be able to spot trends. Test results, |
|              | graphs ans similar shall be stored for comparison reasons and|
|              | product evolution understanding between different OPNFV      |
|              | versions and/or configurations.                              |

|              | respectively. Each packet_size/port_amount combination is run|
|              | ten times, for 20 seconds each. Then the next                |
|              | packet_size/port_amount combination is run, and so on.       |

|step 1        | The hosts are installed, as server and client. pktgen is     |
