Abstract:
A method for enforcing a transmission control parameter for a virtual connection comprising multiple cells within an input port, said virtual connection having a nominal inter-cell arrival rate increment, wherein each of said multiple cells are associated with a theoretical arrival time and an early arrival limit, said method comprising the steps of:delineating a lower boundary of a good zone by determining a difference between the early arrival limit and the theoretical arrival time; delineating an upper boundary of said good zone by determining the remainder after subtracting from the theoretical arrival time the sum of the early arrival limit and the nominal inter-cell arrival rate increment; determining an actual arrival time for an incoming cell from said multiple cells; comparing said actual arrival time to said upper boundary and said lower boundary to determine whether or not said actual arrival time falls within said good zone;and in response to determining that said actual arrival time falls within said good zone, identifying said incoming cell as conforming to said transmission control parameter.
