The CNTT Reference Model specification contains some information and requirements where VSPERF (and other projects) need to respond and enhance their current capabilities to address the implied testing more fully.
For example, the current (9/11) reference model master .MD has:
Per VNF-C, per vNIC, and per vCPU have implications on VSPERF testing features, and may require new methods in TST 009
For example, the Test Setups in TST 009 begin to address the needed Per-V* testing, in Section 6.2,
where the Multiple PVP configuration can be used to assess performance of 1, 2, 4, 8, 12, 16, parallel VMs (or Pods), and a characteristic curve can be provided using the same resources and TST001 workload profile as the VNF of interest (if this specialization is needed). This setup assumes that the Benchmarking Goals and Use cases (Section 6.1 of TST009) require pairs of ports and bidirectional testing. Single port unidirectional testing is also possible with Multiple PVP.
The Test Device/Traffic Generator needs to generate flows designed to pass through the vSwitch and reach the VM, where the processing needed to return the flows takes place.
vNICs themselves can be monitored for octets transferred, and ultimately the limiting bottleneck of each multiple parallel VM setup should be determined.
