Hi,

ns-3 by default comes with OpenFlow version 0.8.9, are you going to update the ns-3 version to 1.3 or you're going to use an external library?

Thank you for your time.

Cheers,

Noel

I don't know how to modify that library, however the OFSwitch13 module uses another library for OpenFlow processing so I think you want to modify that one.

You have to modify the ofsoftswitch library to use GTP with OFSwtich13.

Add the GTP protocol description on the customnetpdf.xml file and update de parser at nbee_link. Then create you new OFPXMT_OFB_ matches for GTP handling and update the source code to match your changes.

This is not a so easy task, you have to explore the source code to understand how it works.
