I am developing a new software for my Internet cafe, with which I can understand the complete details like DTP works of a particular day, month, year or between two dates, its detailed reports, Internet browsing details of certain criteria like on a specific day or month or two dates etc.

I have to know in detail about the total dowload on a particular day on a machin in my cafe. I have 7 computers in the cafe each is attached to a switch. I have a DSL connection. We can see the packets sent and received using the network properties. Here I need to know the incoming and sent data in bytes or MBs.

Can anyone of you help me?
