ABSTRACT:
A method of early data frame release using a modified High-level Data Link Control (HDLC) protocol. A destination link station delivers received data frames immediately upon receipt. The data frames are directed to an intelligent application layer with sufficient information to permit resequencing the out-of-order data frames to maintain data synchronization. A transmitter maintains and assigns sequential sequence numbers to each of a plurality of data frames in a radix cycle from zero to seven and back to zero. A transmit toggle bit enables data frame receipt confirmation with the transmitter altering the transmit toggle bit each time the same sequence number is reused. Each data frame must be confirmed before a sequence number can be made available for reuse.
