he following document provides an outline of the Napatech NFV NIC with OVS Acceleration solution. Designed specifically for NFV use cases, the Napatech NFV NIC accelerates user-space OVS without the need for hypervisor bypass solutions, such as PCIe Direct Attach or Single Root Input Output Virtualization (SR-IOV), but ensures that OVS continues to operate in user-space with DPDK as the interface to Virtual Network Functions (VNFs). In this manner, the throughput performance of OVS can be accelerated up to 7x compared to standard Intel NIC-based solutions supporting OVS and DPDK, while at the same time enabling full VNF mobility. In addition, full theoretical 40G throughput performance can be achieved using less than 1 CPU core, which is an 8x saving compared to standard NICbased OVS
