Abstract:
1. A method for policing packets in a data packet flow arriving at a network device provided with a token counter having a token count (tc) at an arrival time (ta) when a packet is received at said network device, the method comprising the steps of: a) receiving a packet at the network device having a token counter characterized by a token count (tc) corresponding to an arrival time (ta) of the packet; b) evaluating a value (Xp) of said token count (tc) using a predictor function (fp); c) denoting said packet as one of a conforming packet and a nonconforming packet based upon the value (Xp); d) storing the arrival time (ta) of the conforming packet in a variable Last Past Time (LPT); and e) repeating steps (a), (b), (c) and (d) until said packet is a last packet in the data packet flow to arrive at the network device wherein said predictor function (fp) is at least a function of a size of the packet and the arrival time (ta).
