How to see how much data is used by computers on a network

Question

Hi, (I already asked this, but posted it in the wrong place... apologies)
How can I tell the amount of data that some computer has downloaded from the Internet (via my airport extreme (new model))? I have an ADSL connection with a limit on the amount of data I can download (15GB). For some reason, I have almost reached this limit in two weeks! Normally, I only use up about 2GB per month.
Thanks for your attention!

Hi valery,
Thanks a lot for your instant reply on SDN.
But i didn't get what you explained me as I am new to WebDynpro Java
If you could explain me this in step by step process & coding involved.
i have created a new value node in component controller to bind it with table & initially having RFCNAME_Input in component controller.I have added attributes required for treetable to this new value node & also placed a recursive node in it.
Then, i have placed elements of RFCNAME_Input->Output->Lt_org_unit node to an arraylist.
After this i am not able to proceed.
I would be very greatful to you if you can spare some time & help me.
Thanks & Regards,
Ankur
<b>
code i wrote for populating arraylist.:</b>
IWDNode tnode = wdContext.nodeTest_Org_Unit_Input().nodeOutput().nodeLt_Org_Unit();
int size = tnode.size();
final Collection modelObjects = new ArrayList(size);
for(int i = 0;i<size;i++)
final IWDNodeElement tele = tnode.getElementAt(i);
final Object model = tele.model();
modelObjects.add(model);
