Open vSwitch is the default network switch in the XenServer virtualization platform since its version 6.0, and in the Xen Cloud Platform via its XAPI management toolstack.

In addition, Open vSwitch is designed to support transparent distribution across multiple physical servers by enabling creation of cross-server switches in a way that abstracts out the underlying server architecture, similar to the VMware vNetwork distributed vswitch or Cisco Nexus 1000V.

The standard Open vSwitch's (OVS) performance has shortcomings that must be resolved to meet the needs of NFVI solutions.

OVN

OVN complements the existing capabilities of Open vSwitch to add native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups.

Pica8

The company's approach is to combine commodity network hardware (from manufacturers like Accton, Foxconn, Quanta ) with Debian Linux, L2/L3 protocol stacks, a full enterprise feature set, OpenFlow controller and Open vSwitch (OVS) to create both a more "democratic" SDN solutions with competitive price compared to conventional embedded switches as well as more flexible and scalable disaggregated enterprise white box networking solutions.

Network virtualization

The main bypass technologies are either based on a limited set of features such as Open vSwitch (OVS) with its DPDK user space implementation or based on a full feature and offload of Linux processing such as 6WIND Virtual Accelerator.

List of SDN controller software

The de facto technology of the SDN controllers is to manage the Linux kernel features made of L3 IP routing, Linux bridges, iptables or ebtables, network namespaces and Open vSwitch.

Nicira created their own proprietary versions of the OpenFlow, Open vSwitch, and OpenStack networking projects.

Data Plane Development Kit

Open vSwitch (OVS) has a limited set of features running userland that can be leveraged to bypass the Linux kernel OVS processing.

The main purpose of Open vSwitch is to provide a switching stack for hardware virtualization environments, while supporting multiple protocols and standards used in computer networks. Open vSwitch is a software implementation of a virtual multilayer network switch, designed to enable effective network automation through programmatic extensions, while supporting standard management interfaces and protocols such as NetFlow, sFlow, SPAN, RSPAN, CLI, LACP and 802.1ag.
