Hi,

 

I am writing my first dissector and it needs to dissect a packet base on some information in previous packets.  The protocol also allows multiple of these stream mux together.  What is the best way to create a stateful dissector?  From the dev guide, I notice there are two different mechanisms that is “stateful” – the tap and the “conversation”.  From what I can tell, tap seems to be for post-processing of stats only.  So is the “conversation” mechanism the best way to implement a stateful dissector?  Did I miss any some other mechanism?

 

Regards,

Kenny Ho
