Let's imagine that a LAN house, solve to charge financially your users, through of data usage consumption and not by time of use.
It Is possible do control individually of assignment of data usage for users connected to a private network? is possible to assign this consume of controlled way and with safety?
Example One: The user paid to use 1GB of data and passed using for four hours doing search at the google.
Example Two: Some other user paid for the same 1GB but passed using for one hour playing some game MMORP (that consume very many data)
After consume this data, the connection is finished, equal when the time ends out in LAN houses
Exist technology for to do this type of control?
Someone already saw some enterprise working in this way?
