Expected Incompatibilities with Other Projects

OVSDB is considered incompatible with applications that program the flow tables on vSwitches. This includes:

GBP OpenDOVE VTN

These projects have not held discussions as to how to become compatible because they each provide their own solution to the same problem.

Compatibility with Previous Releases

Removed APIs and/or Functionality

The BridgeDomain APIs are removed since they were deprecated in Helium. The APIs were not used.

Deprecated APIs and/or Functionality

The OVSDB northbound API might be depreciated depending on the outcome of the AD-SAL deprecation. The APIs currently use some AD-SAl dependencies.

Changed APIs and/or Functionality

Themes and Priorities

  • Increasing unit and integration test coverage to improve code quality

  • Deprecate AD-SAL dependencies

  • Provide an MD-SAL interface to OVSDB for crud operations

  • Providing Project: OVSDB

  • Requested Deliverable Name: OVSDB interface

  • Needed Milestone:

  • Requested Deliverable Description: We only require the ability to query and instantiate non-OpenFlow information such as ports, bridges, tunnels etc. We prefer the existing OVSDB plugin OVSDBInventoryListener interface and not an md-sal interface due to time constraints.

  • Needed Milestone: M2

  • Requested Deliverable Description: Working MD-SAL OVSDB SB plugin for communicating to node independent of netvirt. We only require the ability to query and instantiate non-OpenFlow information such as ports, bridges, tunnels etc. This is probably a duplicate of the SFC request.

Test Tools Requirements

This project plans on using System Test (ST) inside the OpenDaylight cloud. In particular, the integration piece of OVSDB's Netvirt will require an Openstack Installation that uses ODL as the Neutron ML2. It is the goal to integrate with both Icehouse and Juno.

Update: Flaviof talked with Than and is currently convinced that the infra provided by jjb and sandbox is all that will be needed in terms of infrastructure to have automated tests on OVSDB functionality in Lithium. The plan will utilize VMs of the label 'dynamic_devstack'.
