The Open vSwitch team is pleased to announce the release of Open vSwitch 2.7.0:


This release includes the first non-experimental version of the DPDK datapath.  DPDK provides fast forwarding performance by bypassing the kernel and processing all packets in userspace.

A few other feature highlights of 2.7.0 include:

 - OVN QoS is now implemented via egress shaping rather than ingress policing.

 - OVN supports DSCP marking.

 - OpenFlow packet-out messages are now supported in bundles.

 - On supported platforms, connection tracking now supports TFTP ALG.

 - Support for Linux kernels up to 4.9.

 - And many others.  See the full change log here:


In addition to the 2.7.0 release, we've also released 2.5.2:


This release contains bug fixes for 2.5.1.

Open vSwitch is a production quality, multilayer open source virtual switch. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces. Open vSwitch can operate both as a soft switch running within the hypervisor, and as the control stack for switching silicon. It has been ported to multiple virtualization platforms and switching chipsets.
