ODL replace Switches Mechanism driver in openstack

Hi I am researching on integration of OpenStack and ODL. I am presenting a seminar and your contribution would be a great help for me.

If i have physical switches from different vendors in my environment and I have ML2 mechanism drivers for those switches. Suppose these physical switches support OpenFlow. By Introducing ODL into my infrastructure, can i remove the mechanism drivers for these switches.

Does we need the drivers for physical switches to work with ODL. Does ODL has capability to create ports on physical switches and attaching them to network ports on hypervisors.

How ODL will manage topologgy and path database ?

Opendaylight supports multiple southbound protocol plugins such as OpenFlow, OVSDB, NetConf, SNMP, etc... For OpenStack integration especially, we have a few solutions and we are rapidly converging on using OpenFlow and OVSDB to orchestrate the virtual-network.

Please go through this video : to get an understanding on what can be achieved using OpenDaylight's OpenStack integration.

Essentially, OpenDaylight ML2 Plugin will replace device specific plugins and provides the network abstraction for a network that is formed by virtual and physical entities.

We also have another project named VTN which provides similar capabilities using OVSDB and OpenFlow : Interface

Also, Opendaylight SDN Platform provides a few of Network-service-functions that can handle Topologies for various southbound protocols (including OpenFlow) and also provides path calculation algorithms to operate on top of these discovered topologies.

With all these capabilities, you wont need any specific driver for physical switches to work with ODL.
