1. I used a pre-built version of Helium SR2. It depends if you want to change the source code or add a module or not. I had no need for that, therefore I used the pre-built version. 2. You can control the bandwidth using meters or queues. meters only work with CPqD's ofsoftswitch13 while queues work with ovs (I think it also works with ofsoftswitch but never tried). 3. Read the OVSDB document and check the OVSDB API that ODL provides. You can create queues, assign them to flows, defining the priority, minimum and maximum rate. These are postman collections provided by them: https://www.getpostman.com/collections/9b87f95024e9c8a3a415 and https://www.getpostman.com/collections/c7b1c4fa535c08b56f23. 4. I tested with iperf, a tool that mininet already provides. 5. You can fetch interface statistics using ovsdb REST API or of REST API.

Thanks nuno..I will follow these steps, and I will let you know.. :-)

Hi Nuno, Could you tell me how to make a connection between pre-built version lithium ODL and OVSDB in order to use the collection for Queues definitions?

Hi Nuno and Karthik330, did you manage to create queues and map them to flows using ODL and OVSDB? please could you tell me how or send me some source code,? please I am working on Video QoS usecase as well Thanks
