I used to work for a college internet tech support. We had 5GB daily caps. We found that one IP was doing DOS attacks on some IPs of people he gamed with or something stupid like that. Downloading was tracked in the switch so if someone sent garbage data it would count against the user. The only way to get around inaccurate data is to force people to run a program on their computer that tracks downloading at the application layer of the OSI model. It would have be ran on every computer/device on their network.
There is no way to get around this and there is no way they will be able to force people to run some stupid ISP program on their computers especially since people will have gaming systems and non-mainstream OSes.
There just is no legit way to do metered billings on a TCP/IP network. -- Democrats are not Socialists any more than Republicans are.
Are you going to go through the monthly logs with a customer no matter how long that takes when they dispute the overages and the higher bill? Then try to determine what legit and what was not?
An lets not forget virus and spyware traffic and that the customer is computer illiterate and has no idea what a GB is. -- Democrats are not Socialists any more than Republicans are.
