functest.opnfv_tests.openstack.vmtp.vmtp module

VMTP is a small python application that will automatically perform ping connectivity, round trip time measurement (latency) and TCP/UDP throughput measurement for the following East/West flows on any OpenStack deployment:

  • VM to VM same network (private fixed IP, flow #1)
  • VM to VM different network using fixed IP (same as intra-tenant L3 fixed IP, flow #2)
  • VM to VM different network using floating IP and NAT (same as floating IP inter-tenant L3, flow #3)
