Python NetFlow v9 parser and UDP collector

This script is able to parse incoming UDP NetFlow packets of NetFlow version 9.

Version 9 is the first NetFlow version using templates. Templates make dynamically sized and configured NetFlow data flowsets possible, which makes the collector's job harder.

Development environment

I have specifically written this script in combination with NetFlow exports from softflowd v0.9.9
