MULTIPLEX TRANSMISSION APPARATUS AND MULTIPLEX TRANSMISSION METHOD

摘要

The present invention provides a multiplex transmission apparatus that conducts a traffic control and a discard priority control on an ATM network 2 for transferring IP packets having a plurality of QoS conditions set therein. A multiplex transmission apparatus according to the present invention transmits an IP packet 3 to the ATM network 2. The multiplex transmission apparatus includes intermediately generated packet generation means 12 for generating an intermediately generated packet (CPS packet) having second header informatio n "CID" based on first header information "DSCP" of the IP packet 3, buffer storage means 13 for storing the intermediately generated packet in any of a plurality of transmission waiting buffers 14 ~ to 14n based on the second header information "CID", takeout means 16 for taking out the intermediately generated packet from the transmission waiting buffers 14~ to 14n according to the second header information "CID", and ATM cell transmission means 17 and 18 for loading an ATM cell 4 with the intermediately generated packet taken out and transmitting the ATM cell 4 to the ATM networ k 2.
