<p>PURPOSE:To use the system in a state where a heavy load is applied to a communication line by providing a packet detection means to be sent to a switching means based on the packet transmission state on a packet storage means. CONSTITUTION:A packet receiving packet switching is distributed to input communication lines 12a, 12b,..., 12n and the packet is stored tentatively to buffers 11a, 11b,...11n provided corresponding to the communication lines 12a, 12b,..., 12n. A control means 15 detects the packet transmission state and inputs the packet transmission state to a buffer. The buffer analyzes the packet transmission state and recognizes idle output communication lines 13a, 13b,..., 13n and detection means 114a,114b,..., 114n in the buffer seek a packet going to an idle output communication line from the packet stored in itself, and output it to a switch 10. Thus, the system is used while a heavy load is applied to the communication line.</p> |
