  22 |test purpose  | To evaluate the IaaS network capability with regards to      |
  23 |              | network utilization, including Total number of packets       |
  24 |              | received per second, Total number of packets transmitted per |
  25 |              | second, Total number of kilobytes received per second, Total |
  26 |              | number of kilobytes transmitted per second, Number of        |
  27 |              | compressed packets received per second (for cslip etc.),     |
  28 |              | Number of compressed packets transmitted per second, Number  |
  29 |              | of multicast packets received per second, Utilization        |
  30 |              | percentage of the network interface.                         |
  31 |              | This test case should be run in parallel to other Yardstick  |
  32 |              | test cases and not run as a stand-alone test case.           |
  33 |              | Measure the network usage statistics from the network devices|
  34 |              | Average, minimum and maximun values are obtained.            |
  35 |              | The purpose is also to be able to spot trends.               |
  36 |              | Test results, graphs and similar shall be stored for         |
  37 |              | comparison reasons and product evolution understanding       |
  38 |              | between different OPNFV versions and/or configurations.      |

  51 |              | system.                                                      |
  52 |              | sar is normally part of a Linux distribution, hence it       |
  53 |              | doesn't needs to be installed.                               |
