<p>PURPOSE:To reduce the processing load of routing and the congestion of a traffic by distributing and transmitting packets to plural logical channels in the transmission system of asynchronous information. CONSTITUTION:In a packet terminal 1, the information is divided into the plural packets and transmitted. In a switching node 2, the destination terminal information of the packets is read by a destination node reading part 3, the logical channels are assigned corresponding to the destination node number by a logical channel assigning part 5 by referring to a logical channel assignment table 4, the packets are outputted to physical links corresponding to the logical channels by a routing part 6, outputted through a buffer 7 to the other switching node. Then, the destination packet terminal is identified by a terminal identifying part 8, the sequence of the packets is controlled by a sequence control part 9, and the packets are outputted to a packet terminal 10. Thus, the transmission information of the terminal is distributed to the plural logical channels, transmitted to the other switching node, the plural packets from the other switching node are synthesized and outputted to the destination terminal, and the packets from the other switching node are repeated to the other switching node.</p> |
