You'll not only need to reassemble the packet streams, you'll also
need to know what protocol was used to transport the higher-level
data. For example, was the data flowing over a "connection" to a
file server? if so you'll need to work out which protocol was used
(NFS, CIFS, NCP, something else...). Or if it was carried by EMail
you'll need to extrace the message text from the SMTP (or POP or
IMAP) protocol information and then (perhaps) extract individual
attachments from the message, and then reverse the Base64 encoding
(or whichever it was) and then...
