Disclosed is a method for preventing transmission delay occurring when transmitting packet data to a destination in a transmission module including a first memory having a first memory area for storing packet data to be transmitted and a second memory area for backing up the first memory area, a second memory connected to a transmission link, and a frame processor. The method comprises storing a copy of the packet data stored in the second memory area according to a state of the second memory; deleting the packet data stored in the second memory area if copy of the packet data stored in the second memory is transmitted; determining whether packet data combining is possible according to a state of the second memory area; and if the packet data combining is possible, combining the packet data stored in the first memory area with the packet data stored in the second memory area and storing the combined packet data in the second memory. <IMAGE>
