processes using Internet connection

[sachin jesukaran]

actually i want something like what the netstat -b command does on the
desktop.
it displays the application names that are using the internet
connection and how many bytes were consumed by each applications.

something like the SPB GPRS monitor app which displays the app name
and the bytes consumed.
you can check it here http://www.spbsoftwarehouse.com/products/gprsmonitor/.

if anyone can please guide me about the steps or direction to go to
acheive this ie any classes or native libraries available to implement
the same.

any kind of inputs would be really helpful.
