Hi Anders,

 Not necessarily if we can hide the fact in the tvb or reassembly

But the dissectors create the tvb from the reassembled data. So, if we
define a new type of tvbuff which has to be used, wouldn't that effect the
dissectors?

I think the first step is to find out how feasible this idea is and an
implementation strategy. gziped files, encrypted files etc may prove the
idea not valid.


I understand that feasibility could be a concern in the sense that "we cut
down memory usage without *any* loss in performance* because that would
depend on how well we can tune the cache. I was thinking that the file
backing the tvbuff would be a separate file and not the capture file. In
that case, encryption and compression of capture file wouldn't matter. Am I
missing something here?

Cheers
