Hi
Basically I'm doing my degree project to decode sctp protocol. so i'm not really concerned with the size of data right now.

You may want to have a look at CoMo:

From the "Publications" section:

I suppose it depends on your requirements and how much/little code you
want to write.
What application layer protocols are you interested in (i.e. decodes)?
Or is it just basic IP/TCP/UDP info enough? Are you firmly set on using
the decodes/logic (data) Wireshark supplies (if so, then you'd need to
write some code to extract that and then import it somehow (tshark -T
pdml?))?
It'd be interesting to hear your requirements/use case and your
estimated data set size.
FWIW, a while back I wrote a couple of "off-the-cuff" (quick and dirty)
scripts that did a simple nightly export from a firewall log that had
about 2GB of data. I then stripped it to just IP/port address pairs and
timestamps and maybe a small proprietary firewall tag (varchar) field or
two. The other script deleted any existing indexes and then did a bulk
data load into a PostgreSQL table and then re-created the indexes.
What surprised me was how slow this process was... with a 2-way Xeon 2.6
GHz box, SCSI disks and 2GB RAM (I wish I could remember some queries I
did and the load/import times, sorry). Depending on your queries and the
amount of data you actually load into the tables, and obviously your
hardware, you may be in for a rough/slow ride.
I don't intend to discourage you, just to pass along some very basic
info from an admittedly simple test/trial I did.
Like most things, it just depends on your requirements/data sets and
whether the performance/load is acceptable.
The paper I referenced above had some references to other projects that
you might find useful.
Hope this helps, -Nathan
