This is a PacketIn event handler, so the event object is a PacketIn. You can either grep the codebase for class PacketIn, or you can look up the PacketIn event in the POX manual. It's in a subsection called PacketIn under OpenFlow Events: Responding to Switches.

You can search the codebase for class Connection, or you can look it up in the manual. It's in a subsection called Connection Objects. For either or both of these, you could also use Python to find the answers for you. For example, to find the class of the connection, object, insert the following near line 86 of l2_learning: import inspect print inspect.getsourcefile(type(connection)), inspect.getsourcelines(type(connection))[1] Et voila, it'll print out the file and line number of the class. Or simply insert help(connection) to get the whole pydoc for it. Or save it to a global variable, run the POX py module, and then do help(global variable name) from the commandline. Hope that helps. -- Murphy Thanks and regards. -- 吾輩は猫である。ホームーページはhttp://introo.me。

Thanks and especially for the three methods. Regards. 2014-04-17 4:50 GMT+08:00 Murphy McCauley murphy.mccau...@gmail.com: On Apr 16, 2014, at 3:27 AM, Shiyao Ma i...@introo.me wrote: Hi.
