Target Audience: Those who are new to VSPERF and would like to try it out locally.The requirements depends on mainly two things (a) Topology and the (b) Mode. In this page, we will describe the minimal requirements considering both the topology and the mode.

Experimenting with Single System:

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

  1. OS: Linux (ex: centos)
  2. Hypervisor: KVM/Qemu
  3. RAM:  8-16GB
  4. TGen-VM: TRex-VM (VSPERF includes this image as part of its artifacts - https://artifacts.opnfv.org/vswitchperf/vnf/vloop-vnf-ubuntu-16.04_trex_20180209.qcow2)
  5. VNF: vloop-VNF (VSPERF includes this image as part of its artifacts - http://artifacts.opnfv.org/vswitchperf/vnf/vloop-vnf-ubuntu-14.04_20160823.qcow2)

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.)
