Sometimes people ask me a tutorial about PF_RING. Last year I have given a tutorial about it at the IM 2009 conference. I think that everyone interested in using PF_RING for going beyond packet capture acceleration should read this set of slides I used for the tutorial. Today the cost of packet capture is limited with respect to packet analysis. For this reason you should use PF_RING as a framework for creating simple yet powerful traffic monitoring applications.
