| 1. A method of processing, in a receiver of a communication system, a data frame received from a transmitter, the received
data frame having a sequence number, the receiver having a queue indexed by said sequence numbers, comprising:
if said data frame is sequential to previously received sequential data frames, processing said data frame;
defining an inactive window in said queue, said inactive window comprising contiguous queue entries, and wherein the size
of said inactive window is negotiated between the receiver and the transmitter;
if said data frame falls within said inactive window, discarding said data frame; and
if said data frame is nonsequential to previously received data frames and falls outside said inactive window, storing said
data frame in said queue.
