Question

i am new to Openflow but what i read is that it provides user to modify flowtables in switches to change routing and for this purpose we use a controller.

Now for my project, i have to develop a controller or may be use some existing and modify it as per research requirements. From what i have seen NOX is most famous contorller but it is written in C++ and i am not good in C++ so i wanted to opt for a java based option. Most openflow frameworks i think offer full simulation environment where we can also create switches/firewall etc, but in my project i already have physical nodes that support openflow feature.

With this in mind, can you please recommend me a simple java based Openflow controller that i should use to be able to contorll traffic flow in these nodes??

Try using Floodlight from Big Switch Networks. It is quite stable, and is being tested in production by Big Switch.
