Until we hear the whole story I wouldn't blame the datacenter people. Maybe
they do have traffic shaping but they allow bursts (and chances are the
"bursts" are now "normal"). Probably the best way to measure the bandwidth
use would be MRTG (http://oss.oetiker.ch/mrtg/) and many datacenters use
that. But, beyond MRTG, traffic analysis is an expensive exercise and is not
part of a normal hosting offer (so in order to tell who is using the
bandwidth one would need some additional software/services - web traffic is
an exception as many hosting companies are including traffic reports in
their hosting packages).

This is the second post like this that I heard in a while. I'd like to
grab "data center people" like this and slap them accross the head (sorry,
a moment of excitement). If they are smart enought to think this is true
of you, and have the tools that (accuarately?) tells them this,....then
they should be able to answer these questions for you:
1. How much bandwidth are we using?
2. Where is it going?
3. What is the traffic profile? (Protocols, From where, To where)
4. If you can not answer #1-#3, then how do you really know our bandwidth
is too high?
5. Why is our limit so low?,...and why haven't you raised it? (this isn't
the dark ages anymore).
6. Why hasn't there been "traffic shaping" devices been put in place to
throttle bandwidth so that it is not possible to exceed a particular set
limit so that you don't have to bother me with your complaints of my
alleged bandwidth excesses.
I don't know what kind of answers you get,...but it's sure be fun to ask.
There is no such tool that will do all that and put all the right
information in front of you nice and neat and clean. It takes a lot of
work and usually more than one tool and the accuarcy is always
questionable (hence #4 above). In fact that is why "traffic shaping"
devices (that actually work correctly) cost $$$$$$$$.

Our data centre claims me that our overseas traffic bandwidth exceeds our
limit. I have logged all the traffic packet. Can you recommend me a
best tool to analyze the traffic packet. I want to know:
1) which IP the traffic comes from
2) how much bandwidth for the incoming and outgoing traffic
3) which port generate the traffic
4) the source IP address
