<p>PROBLEM TO BE SOLVED: To eliminate a delay generated by a sequence control even for a packet in which the sequence control is not required. SOLUTION: A packet exchange system divides a receiving packet into a plurality of blocks at an input line side, cascade connects and exchanges a plurality of sets of unit switches, and reassembles the packets at an output line side. In this system, a flag 15 for indicating whether a sequence control is necessary or not at the divided blocks 39 is imparted to the input line side. When the block has the flag having no necessity of sequence control, an output is produced at the output line side according to a packet assembling completion of itself irrespective of the time sequence with another packet.</p> |
