Hi, [1] is a doc comparing OVN and ODL for Neutron. I wrote it in March so some info might be stale. Hope this can be useful, comments are welcome!

When you ask the question: "How can OVN or ODL solve being a backend layer for Neutron?", for example, the answer with OVN is simple: You do it this way, and it works. For ODL, the question is much more nuanced, as it depends on *what* components in ODL you are using. Also, yes, the comparison between "ML2+python agents" vs. "ML2+OVN" is much more relevant IMHO.

That is true, but when considering a Neutron backend for OpenStack deployments, people choose a subset of OpenDaylight projects and the end result is a solution that is comparable in scope and feature set. There are objective differences in where the projects are in their lifetime, the HA architecture, the project's consistency model between the neutron-server process and the backend, the development velocity, the community size and the release model. > > __ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

[openstack-dev] [neutron][networking-ovn] OVN vs. OpenDayLight
I'm trying to reconcile differences and similarities between OVN and OpenDayLight in my head. Can someone help me compare these two technologies and explain if they solve the same problem, or if there are fundamental differences between them?
