Abstract:
A transport protocol process for transmitting data from a sending station to a receiving station over a wireless link, wherein said protocol prohibits using positive acknowledgement (ACK) packets, said process comprising the steps of:transmitting, by said sending station, a plurality of sequential data packets to said receiving station, wherein each said plurality of sequential data packets form a respective Group-of-Packet (GOP); detecting whether any of said received data packets in each current GOP are corrupted before receipt of all data packets in said current GOP; transmitting, by said receiving station, a negative acknowledgement (NAK) packet to said sending station, before the receipt of all data packets in said current GOP, only if at least one of said data packets in said current GOP is corrupted, wherein said NAK packet indicates corrupted data packets; and selectively transmitting, by said sending station, said data packets indicated by the received NAK packet before transmitting the next GOP to said receiving station if a predetermined time is unexpired, wherein the prohibition of said ACK packets reduces data propagation delays.
