Create performance test for vBNG VNF

[lixuna]

Goal: Testing Throughput, latency, resource util per unit of performance

VMs:

• vBNG
• Packetgen
• (VXLan VM) may not be needed

Tasks:

• Investigate ability to do testing with Packetgen + vBNG w/o the need for vxlan.
  • Remove vxlan as requirement in this issue if that is possible
  • Update vBNG VM configuration to use needed network setup via ticket Create vBNG virtual machine for KVM #31
• Create script to use Packetgen for testing vBNG VM
• Create top-level comaparison script for testing vBNG
  • create vBNG_vm_test.sh to start VMs and run the test. Eg.
    • Starts vBNG VM
    • Starts Packgen VM
    • Runs tests from packgen vm
  • Test script with no VMs running

top-level script created with the following functionality:
/vBNG_vm_test.sh

• Update host network (VPP) with configuration needed for vBNG
• (if necessary) Create vBNG and Pktgen VMs
• Run benchmark
  • Low throughput by default (2002pps)
  • Higher throughput can be specified when running script
  • ./vBNG_vm_test.sh <rate> (e.g. 10Kpps, 1Mpps)
• Remove vBNG and Pktgen VMs
  • ./vBNG_vm_test.sh clean
