 The current release of OPNFV (Arno) enables continuous integration,​ automated deployment and testing of components from upstream projects such as Ceph, KVM, OpenDaylight,​ OpenStack and Open vSwitch. The combination of these provides an initial build of the NFV Infrastructure (NFVI) and Virtual Infrastructure Manager (VIM) components of the ETSI NFV architecture.\\ \\ The current release of OPNFV (Arno) enables continuous integration,​ automated deployment and testing of components from upstream projects such as Ceph, KVM, OpenDaylight,​ OpenStack and Open vSwitch.

-Open vSwitch is an open source virtual switch providing Virtual Networking services in the NFVI. It provides network connectivity from Virtual Machines (VMs) to the physical network and between Virtual Machines. The default deployment of Open vSwitch in OPNFV implements the software fast path as a Linux Kernel Module. This kernel module caches recently used flows in order to quickly forward subsequent packets in the same flow space. The kernel datapath, however, is not necessarily designed or targeted to meet the requirements for the NFVI, and we need to make collaborative efforts toward ​enabling ​NFV features. Although Open vSwitch gives adequate performance in many cloud and enterprise use cases, when used in Telco NFV use cases, the performance may not be sufficient in terms of throughput and latency, particularly for small packet sizes.\\ \\+Open vSwitch is an open source virtual switch providing Virtual Networking services in the NFVI.

 Technologies such as DPDK and ODP have shown that running packet processing workloads in userspace software can improve the performance in terms of throughput and latency. The advantage of this is apparent in recent work done on the Open vSwitch userspace forwarding plane which has shown 10x improvement in packet throughput with respect to the Open vSwitch kernel space dataplane. This is demonstrated via the OPNFV vsperf project. \\ \\ Technologies such as DPDK and ODP have shown that running packet processing workloads in userspace software can improve the performance in terms of throughput and latency.
