Hi,

I see there are lot of ways through which we can integrate ODL with Openstack.Here

  1. Through ML2 plugin of neutron talking to ODL northbound (neutron), and on southbound side of ODL we have OVSDB which manages the Ovs switches.
  2. Using VTN manager of ODL.

Can anyone share some insight as what is the difference between these two implementation? Which one to prefer depending on use case? Or any link in this regard will be highly appreciated.

OVSDB NetVirt would look like the default OpenStack Open_vSwitch plugin and works with the OVS switches. The VTN Manager assumes NEC gear is also in the picture.

Both use the Neutron Northbound to get neutron ML2 from OpenStack. Both also use the OVSDB southbound plugin to talk with the OVSDB nodes.

So I would say if you want a default OpenStack and ODL integration you would use OVSDB NetVirt. If you have NEC gear then you can use the VTN.

Hi Shague, VTN Manager does NOT require any NEC gear. VTN Manager just work with a default OpenStack environment.

VTN is a pure OpenFlow based solution that leverages the OVSDB Southbound for the settings in OVS. Does not assume any NEC gear.

VTN has support for all L2 features and we have a service function chaining use case that was demonstrated in the summit. It depends on the use case that you want to try out.
