The access network apparatus and a queue management method for managing a queue in consideration of the real time traffic characteristics

A queue management method for an access network apparatus is disclosed. The queue management method comprising the steps of: receiving a packet, the received packet is real-time transmission when the packet, the method comprising: determining whether to transfer the packet, the packet transmitted in the transmission time in the transmission time, which allows for such a packet at the destination node When possible, we believe, save the packet in the transmission queue, transmission is not possible in the step, and the transmission time-sequentially sent according to the stored sequence, and a step of immediately discarded without storing the packet in the transmission queue . Accordingly, it is possible to save resources necessary for packet transmission. Real-time transport packets, the transmission queue, the access router for the mobile node
