+|test purpose  | To evaluate the IaaS network capability with regards to      |
+|              | network utilization, including Total number of packets       |
+|              | received per second, Total number of packets transmitted per |
+|              | second, Total number of kilobytes received per second, Total |
+|              | number of kilobytes transmitted per second, Number of        |
+|              | compressed packets received per second (for cslip etc.),     |
+|              | Number of compressed packets transmitted per second, Number  |
+|              | of multicast packets received per second, Utilization        |
+|              | percentage of the network interface.                         |
+|              | This test case should be run in parallel to other Yardstick  |
+|              | test cases and not run as a stand-alone test case.           |
+|              | Measure the network usage statistics from the network devices|
+|              | Average, minimum and maximun values are obtained.            |
+|              | The purpose is also to be able to spot trends.               |
+|              | Test results, graphs and similar shall be stored for         |
+|              | comparison reasons and product evolution understanding       |
