|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.                              |

|              | Packet size: 64, 128, 256, 512, 1024, 1280 and 1518 bytes.   |

|              | Number of ports: 1, 10, 50, 100, 500 and 1000. The amount of |
|              | configured ports map from 2 up to 1001000 flows,             |
|              | 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.       |
|              |                                                              |

|              | For SLA max_ppm is set to 1000.                              |

|pre-test      | The test case image needs to be installed into Glance        |
|conditions    | with pktgen included in it.                                  |
|              |                                                              |

|step 1        | The hosts are installed, as server and client. pktgen is     |
|              | invoked and logs are produced and stored.                    |

|              | Result: Logs are stored.                                     |

|test verdict  | Fails only if SLA is not passed, or if there is a test case  |
