Telecom companies offer different data rates for home/office purposes depending on the money they pay.
- How are the telecom people able to control the flow of data of different cables?
- Say supposing a cable can be used till $20\textrm{ MBps}$. But he paid only for $5\textrm{ MBps}$ scheme, why is the user not able to steal the remaining bandwidth?
- Is there a multi rate theory behind this?
- Or it is a simple filtering?
