Abstract
In an ATM communication system, a source transmitting in accordance with an Available Bit Rate service category must be policed to ensure that the cells are transmitted at a rate within the cell rate specified by the network at any given time. The usage parameter control system can only store a limited number of pending cell transmission rates to be enforced, and must make approximations by discarding certain stored pending cell transmission rates in order to make room for new cell transmission rates. This invention is directed towards a method for selecting which stored cell rates to discard that allows less cheating room in the cell rate enforcement than does the prior art, and that does not over-police.
