Abstract
An asynchronous transfer mode switching network system relays packets stored in packet buffer units to output ports designated by the packets, and a time slot scheduling unit assigns time slots to the packets stored in the packet buffer units upon arrival at the packet buffer units for preventing the packets from collision in a space division switching unit, wherein each of the packet buffer units sequentially writes new packets into respective memory locations but randomly reads out the new packets in the time slots assigned by the time slot scheduling unit so that the throughput of the space division switching unit is improved.
