US 2013/0155860 A1 · PACKET TRANSMISSION DEVICE AND METHOD OF TRANSMITTING PACKET

Abstract

The inventive concept relates to a method of managing a packet being transmitted through a packet transmission network. The method may include distinguishing a buffer unit corresponding to the received data packet among a plurality of buffer units according to a type of a data packet received from the outside; comparing the number of packets stored in the distinguished buffer unit with a critical value; storing the received data packet in the distinguished buffer unit or a sub buffer unit corresponding to the distinguished buffer unit according to the comparing result; and transmitting the data packet stored in the distinguished buffer unit through a working path of the backbone network and transmitting the data packet stored in the sub buffer unit through a protection path of the backbone network.
