APPARATUS AND METHOD FOR MINIMIZING TRANSMISSION DELAY IN A DATA COMMUNICATION SYSTEM, ESPECIALLY CONCERNED WITH PREVENTING DATA TRANSMISSION DELAY BY USING A DESCRIPTOR AGGREGATION TECHNIQUE
PURPOSE: An apparatus and method for minimizing transmission delay in a data communication system is provided to prevent the transmission delay of packet data by temporarily storing the packet data to be transmitted to a transmitting buffer in a backup queue, directly transmitting the packet data when the transmitting buffer is in an idle state, and aggregating and transmitting newly received packet data and the previously received packet data in case that the transmitting buffer is in a busy state. CONSTITUTION: A transmission module for aggregation consists of a transmission management part(110) and a transmission protocol engine part(120). The transmission management part(110) covers the management of transmission data and preprocessing for a protocol header. The transmission protocol engine part(120) transmits actual packet data according to a transmission protocol. The transmission management part(110) is composed of a transmitting queue(111) and a frame processor(113). The transmitting queue(111) stores data for data management. The frame processor(113) aggregates the packet data stored in the transmitting queue(111). In addition, the transmission management part(110) comprises a backup queue(112) that temporarily stores the packet data to be transmitted to the transmission protocol engine part(120).
