**Note:** For tests where the traffic generator and/or measurement
receiver are implemented on VM and connected to the virtual switch
through vNIC, the issues of shared resources and interactions between
the measurement devices and the device under test must be considered.
+**Note:** Some RFC 2889 tests require a full-mesh sending and receiving
+pattern involving more than two ports. This possibility is illustrated in the
+Physical port → vSwitch → VNF → vSwitch → VNF → vSwitch → physical port
+diagram above (with 2 sending and 2 receiving ports, though all ports
+could be used bi-directionally).

To establish the baseline performance of the virtual switch, tests would
