Using Open vSwitch* with DPDK for Inter-VM NFV Applications

This article walks you through configuration of OVS with DPDK for inter-VM application use cases. Create an OVS vSwitch bridge with two DPDK vhost-user ports, each connected to a separate VM, then use a simple iperf3 throughput test to evaluate performance.
