Java Bandwidth Monitoring

Question

I am developing a Network based Client Server Application where "internet time" is allocated to a client on the computer, which then logs in and use it, but I need a way to also monitor the bandwidth the client uses. I am writing in Java, I know it can be done as we are using such program currently(Bought it few years back) but it is outdated and lacking features.

If it might be an easier job to just monitor the usage of let say, IE, Firefox and Chrome?

Now I am looking for any links to tutorials, help, push in the right direction. I am lost to how to start at it. Tried searching the web, I got a few stuff but can't seem to get the code working as they only give in incomplete.

Answer 1

Here is the link to code which is termed as Internet Bandwidth Monitor. It is simple tool that monitors the uploads and downloads with graph.

Answer 2

A servlet filter that does band width monitoring and possibly throttling might do nicely.
