Re: [OpenDaylight Discuss] [vtn-dev] ODL - Neutron API enhancement to include the southbound driver info

Hi Suchi,

Its my fault that I had not participated in the previous discussions on Affinity + VTN in the virtualization edition &
would like to understand it better.

It would be awesome if you can schedule this meeting sooner (and not wait for releases).
We can find a good solution which everyone is happy with. Am open anytime / any day :-)

Ok, I'll schedule a meeting to decide resolution for next release.

As explained in today's call, I started this discussion with neutron in mind. 

I have to understand the problem with affinity before I can expand this discussion beyond neutron. 

I think Suchi is going to call a meeting this week with everyone interested to go over the problem.

So I see the value of this... But what about Affinity?

Subject: [vtn-dev] ODL - Neutron API enhancement to include the southbound driver info


Hi Kyle, OpenDove, VTN & OVSDB devs,

Since we all have integrations completed with the Neutron nb-apis and these southbound drivers (ovsdb, open-dove, vtn)
cannot co-exist in the same virtualization edition, I was thinking of extending the Neutron NB-API to include the information
on which Southbound driver to choose. By doing that, all of these bundles can co-exist in the same virtualization edition and
based on the Openstack/Neutron deployment, the customer can choose which ODL-southbound to use. This can be done along
with the existing configuration that is needed on the OpenStack to point to the ODL-Northbound API & the authentication details.
something like :

southbound=[ovsdb | opendove | vtn]

We can ofcourse keep this configuration inside the OpenDaylight as well. But, having it done as part of Neutron provides a single
point of configuration and let the Neutron administrator decide on what is to be done, rather than depending on another administrator
who might handle the Opendaylight Controller.

Please share your opinion and I can get this thing done on the Opendaylight side.
