Ryu app is started by neutron-openvswitch-agent in: https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/openvswitch/agent/openflow/native/main.py#L34 Is it what You are looking for? > > Regards, > Niket > __________________________________________________________________________ > 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 — Slawek Kaplonski Senior software engineer Red Hat __________________________________________________________________________ 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
