Openflow controller in java?

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??

why am i given negative vote? any explanation please?? – 911TurboS Apr 18 '12 at 14:12 — 911TurboS, Apr 18 '12 at 14:12

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

You can also try Beacon which Floodlight forked from, see: http://www.beaconcontroller.net/

Is it easy to code beacon? or flood light? for someone with fair java knowledge which should be the preferable controller choice? – Space Rocker Sep 17 '12 at 09:36
