The packet processing apparatus includes a packet memory, a transmission processing unit that writes a plurality of packets to be transmitted to the packet memory to generate a combination packet into which the plurality of packets have been concatenated, a line handling unit that sends packets to a communication line, and a combination packet transfer unit that DMA-transfers the combination packet from the packet memory to the line handling unit. The transmission processing unit writes information on an address in the packet memory of beginning data of an individual packet in the combination packet to a descriptor. The line handling unit separates the DMA-transferred combination packet into a plurality of packets and sends the plurality of packets to the communication line.
