[ixp1200] Deep Packet Inspection using IXP1200 simulator.

Hi, I am a masters student who is just starting work with the IXP1200 simulator. I am interested in performing deep packet inspection using the simulator (v2.0) and analysing the perfromance. Is there any code available for implementing deep packet inspection on the IXP1200 simulator?? Any help or advice will be greatly appreciated. Thanks in advance, Denis Lyons Department of Informatics and Electronics University of Limerick Limerick Ireland.
