Target Audience: Those who are new to VSPERF and would like to try it out locally.

Experimenting with Single System:

In this scenario, both the DUT (vswitch with/without VNFs) and the Traffic-Generator run on same System.

Experimenting with Two Systems

In this scenario, DUT runs on first system and the Traffic-generator runs on a different system. (Note: The second system could be a hardware traffic-generator - Spirent, Ixia, Xena, etc.)
