    摘要: A Buffer Management System for a general multipoint packet switching network where the network has terminals transmitting data in the form of packets belonging to multiple channels over communication links through a packet switch array, the packet switches of the array receiving incoming packets from input data links and having memory arrays for temporarily storing the incoming packets for retransmitting the stored packets over output links. The Buffer Management System determines whether a packet should be stored, retransmitted, or discarded during an overload condition by identifying each incoming packet as either an excess packet or a nonexcess packet based on the number of packets stored in the memory array of the same channel as the incoming packet, and writing an incoming nonexcess packet into the memory array when the memory array is full and at least one excess packet is in the memory array and for discarding the excess packet from the memory array.

    摘要: The present invention is directed to a high performance broadband ATM switching system comprised of concentrator, non-recirculating sort-trap and queuing stages. The concentrator stage concentrates cells entering the switch by discarding idle inputs thereto. Cells arriving at the non-recirculating sort-trap stage during a time slot are sorted based upon destination address and priority. Cells having a unique address for the time slot are placed in a corresponding output queue while cells having non-unique destination addresses are re-routed to a trap buffer which ages the cell until a subsequent time slot in which the destination address is unique.

    摘要: A packet switching apparatus with a number of lines for simplifying the configuration of the packet switching apparatus by reducing the size of the circuit which is to perform at high speed. The packet switching apparatus is suitable for an ATM switching device, for example. The packet switching apparatus is provided with a first packet switching unit 9 for sorting data packets received through a plurality of input lines 1-1 to 1-n into their corresponding output line groups 7-1 to 7-m, 7-(mnull1) to 7-(2m), and so on, and outputting the sorted data packets to transfer lines 2-1 to 2-i, and the second packet switching unit 10-1 for sorting the data packets received from the transfer line 2-1 into their corresponding output lines 7-1 to 7-m and outputting the sorted data packets. Specifically, the transfer line 2-1 transfers a data packet at a line speed faster than a totaled line speed of the output lines 7-1 to 7-m.

    摘要: An ATM switching system includes a plurality of (m) small-scale n×n ATM switch modules, and a coupling module for coupling the ATM switch modules to one another to implement a large-scale ATM switching system. The coupling module includes m concentrators corresponding to the m ATM switch modules. Each concentrator has a multiplexing block for multiplexing m×n signal sequences into n signal sequences, concentration buffer block including a n×n banyan network for specifying one of ATM switch modules for each effective cell based on a destination signal and a plurality of buffers. The concentrator operates at slow transfer rate in a large-scale ATM system so that the performance of the concentrator does not restrict the scale of the ATM system.

    摘要: First to fourth input buffers stores cells inputted from first to fourth input ports, respectively. Each input buffer is equipped with a main buffer section, a plurality of sub-buffer sections connected to the main buffer section in series and a buffer controller for controlling them. A collision judging section judges whether or not a collision occurs between the cells outputted from each sub-buffer section, and the judged result is sent to a cell converter. The cell converter returns a collision information to the buffer controller in accordance with the judged result, and further sends a cell, which has a victory information since it is judged as a victory over the collision, through a sorter to a self-routing section. The self-routing section outputs the received cell to an output port. This configuration enables a shuffle operation to be carried out in the sub-buffer section and the cell converter to thereby avoid the drop of the throughput.
