Hi,
I have recently started learning Openflow using NOX controller. I have downloaded the VMware image available on OpenFlow website having inbuilt NOX controller. I am following the tutorial available at http://openflowswitch.org/wk/index.php/HOTITutorial2010 I require help on following issues, would appreciate if the developer community assist me this: 1. I am new to Python so it takes a bit of time for me to get hold of the APIs which are available in NOX controller. I am looking for some documentation on APIs which I can/would use in programming of NOX controller. I am not looking for generic tutorial on Python. 2. I was able to run the NOX controller using "./nox_core -v -i ptcp: pytutorial" command. In this command the pytutorial is the pytutorial.py file. Would we not require to provide a full path for this file(~/noxcore/src/nox/coreapps/tutorial/pytutorial.py) or the VMware consist of some variables for this particular file? Can I replace this file with say my test.py and run the command normally by "./nox_core -v -i ptcp: test" 3. I am trying to figure out a way in which packets coming from hosts are parsed by the switch using Python. I would like to know the source and destination address of the packets and also the port numbers like 8080,121 etc. Any clues to the types of Python APIs which I would be requiring would be a great help. 4. Also, for generating traffic between the nodes created using mIninet, should I use iPerf or cBench? Thanks, Kavitesh.
