A network router where fragmentation takes place prior to the queuing. After packets are classified, the low priority packets are fragmented and AAL5 and MLPPP encapsulated. The fragments and the high priority packets are PPP encapsulated. Next the packets are queued using an MDRR queuing. All fragments for each packets are placed in the same queue. At the output of the queue, sequence numbers are added to the fragments of each packet. Finally the packets are queued for transmission.
