Abstract
A self-routing multistage switching network for a fast packet switching system suitable for multimedia communication. The self-routing multistage switching network has packet buffer means for storing packets, provided only in an input stage and respectively connected to input ports, and switching networks having no packet storing function and provided after the packet buffer means. The self-routing multistage switching network detects beforehand while packets are transmitted therethrough whether or not the packets are transmitted therethrough instead of being discarded, reports information for identifying the packets which are transmitted instead of being discarded backward to the packet buffer means through transmission routes through which the packets have been transmitted, and deletes the packets stored in the packet buffer means and corresponding to the packets which are allowed to be transmitted through the self-routing multistage switching network after sending out the same packets. The self-routing multistage switching network is capable of transmitting a plurality of packets for a piece of comunication without entailing outrun between the packets.
