Abstract: PURPOSE: A packet transmission device and method are provided to efficiently utilize the bandwidth of a packet transmission network by eliminating the overload of the packet transmission network. CONSTITUTION: A packet transmission device (100) includes a queuing block (140), a scheduling block (150), a classifying block (110), and a load balancing block (130). The queuing block includes multiple buffer units individually storing multiple data packets and multiple sub-buffer units individually corresponding to the multiple buffer units.

The classifying block determines a buffer unit corresponding to a received data packet among the multiple buffer units according to the type of the data packet received from the outside. If the number of data packets stored in the determined buffer unit is bigger than a threshold value, the load balancing block stores a received data packet in a sub-buffer unit corresponding to the determined buffer unit.
