| 4. A method for reducing 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 by storing a copy of the packet data, a second memory connected to a transmission link, and
a frame processor, the method comprising the steps of:
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 when the 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
combining 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 if packet data combining is possible.
