  23 |test purpose  | To evaluate the IaaS network performance with regards to     |
  24 |              | flows and throughput, such as if and how different amounts   |
  25 |              | of packet sizes and flows matter for the throughput between  |
  26 |              | nodes in one pod.                                            |

  31 |              | Packet size: default 1024 bytes.                             |
  32 |              |                                                              |
  33 |              | Test length: default 20 seconds.                             |
  34 |              |                                                              |
  35 |              | The client and server are distributed on different nodes.    |
  36 |              |                                                              |
  37 |              | For SLA max_mean_latency is set to 100.                      |

  40 |test tool     | netperf                                                      |
  41 |              | Netperf is a software application that provides network      |
  42 |              | bandwidth testing between two hosts on a network. It         |
  43 |              | supports Unix domain sockets, TCP, SCTP, DLPI and UDP via    |
  44 |              | BSD Sockets. Netperf provides a number of predefined tests   |
  45 |              | e.g. to measure bulk (unidirectional) data transfer or       |
  46 |              | request response performance.                                |
  47 |              | (netperf is not always part of a Linux distribution, hence   |
  48 |              | it needs to be installed.)                                   |

  55 |applicability | Test can be configured with different packet sizes and       |
  56 |              | test duration. Default values exist.                         |

  67 |step 1        | Install netperf tool on each specified node, one is as the   |
  68 |              | server, and the other as the client.                         |
  69 |              |                                                              |
  70 +--------------+--------------------------------------------------------------+
  71 |step 2        | Log on to the client node and use the netperf command to     |
  72 |              | execute the network performance test                         |
  73 |              |                                                              |
