executions of tests covering a range of VNF service densities
defined as [Number of Service Chains] x [Number of VNFs per Service
Chain]. The results are presented in the service density graph.
+Each graph includes the results of both configurations: one NF per physical
+core and two NFs per physical core and their relative difference.
Additional information about graph data:
#. **Y-axis Labels**: number of service chains.
-#. **Z-axis Color Scale**: lists 64B Packet Throughput (mean MRR/NDR/PDR value)
- in Mpps.
+#. **Z-axis Color Scale**: lists 64B/IMIX Packet Throughput
+ (mean MRR/NDR/PDR value) in Mpps or the Relative Difference.
#. **Hover Information**: specific test substring listing vhost-chain-vm
combinations, number of runs executed, mean MRR/NDR/PDR throughput in Mpps,
- standard deviation.
+ standard deviation for both configurations and their relative difference.
