  • Support for Interface Bidirectional Forwarding Detection (BFD).

  • Improvement in OVSDB Qos and Queue support

  • Code quality, stability and usability

  • Logging improvements

Target Environment

For Execution

Same as the usual JRE requirements for OpenDaylight (JDK 1.8)

For Development

Same as the usual JDK and Maven requirements for OpenDaylight (JDK 1.8, Maven 3.3.9)

Known Issues and Limitations

  • Hardware Vtep currently doesn't support full reconciliation. It only supports connection reconciliation only.

  • Support for auto attaches table is currently experimental.

Migration from Previous Releases

OpenStack Network Virtualization (widely known as 'NetVirt') was part of the OVSDB project prior to the Boron release. Given it's wider scope, this functionality was moved to its own new project (named 'netvirt'). For more details about this migration, please refer to the netvirt projects page.
