    摘要： A schedule management table is additionally provided in a scheduling system comprising: a time slot for specifying, in slots, the cell transfer sequence of individual lines in one turn; a cell read sequence management table having elements to which the lines are set as cell transfer objects; schedule computation means for controlling the setting of the lines to the cell read sequence management table; and allocation processing means for converting the elements of the cell read sequence management table to specified positions of the slots in the time slot. The schedule management table indicates positions, within the cell read sequence management table, to which transfer object lines are newly set, for each PCR (peak cell rate) value. The scheduling system can reduce the necessity of update of the cell read sequence management table and can execute data transfer which assures the rate of each ATM line.

    摘要： The switching network serves for the transmission of digital data signals within a broadband communication system. This switching network is thereby constructed of individual switching elements (KE) that form at least one multi-stage funnel due to a connection to one another. The section for the assemblies of the switching network is selected such that at least one complete funnel is accommodated on the respective assembly. The respective assembly thereby has its external data inputs provided with unidirectionally designed optical/electrical transducers (OML-E) and has its external data outputs provided with unidirectionally designed electrical/optical transducers (OML-S).

    摘要： A method of transferring data between networks includes storing a connection path set between predetermined data from a first network and a predetermined address in a second network during initial connection between the first and second networks, and transferring the predetermined data from the first network along the stored path. Accordingly, data transmission speed is faster by pre-mapping a data path between networks, and hardware and software loads on the gateway for repeating data between networks can be reduced.

    摘要： An ATM switch network with an expansible optical ring, in which each switch forms several paths with a vertical ring, a horizontal ring and an expansible ring. The network has a large-capacity and a small switching interval, minimizing cell delay deviation and rendering the network suitable for high-speed multimedia service. A group switch node is formed by grouping the switches forming the vertical and horizontal rings, thereby enhancing reliability within a transmission interval by bisecting the wavelength division multiplexed logical paths and by using two optical lines. The network discriminates between I/O terminals for matching data having a low-speed small capacity and wavelength division I/O terminals for matching data having a high-speed large capacity. By using a node's I/O terminals, the network interconnects nodes via wavelength division multiplexing optical lines, thereby forming an automatic adaptive network. The network increases switching capacity, thereby improving communications in densely built-in areas.

The apparatus is also comprised of a mechanism for reading or writing the entire ATM cell from or into the memory array. The present invention pertains to a method for switching an ATM cell. The method comprises the steps of receiving the ATM cell at a first input port of a switch from the ATM network. Then there can be the step of storing the ATM cell in one clock cycle in a memory array of the switch. Next there is the step of reading the ATM cell in the memory array in one clock cycle. Next there is the step of transferring the ATM cell from the memory array to a first output port of the switch. Next there is the step of transmitting the ATM cell from the first output port to the ATM network. The present invention pertains to a switch for an ATM cell. The switch comprises I input ports which receive ATM cells from an ATM network, where I≧1 and is an integer. The switch is also comprised of a memory array connected to the I input ports for storing an ATM cell received by one of the I input ports in one clock cycle. The switch also comprises O output ports connected to the memory array, where O≧1 and is an integer. One of the O output ports transmit an ATM cell which is received from the memory array to the ATM network. Additionally, the switch comprises a controller connected to the memory array, I input ports and O output ports for controlling the storage of an ATM cell from one of the input ports into the memory array in one clock cycle. The switch can be used for normal switching operation, multicasting, demultiplexing or multiplexing.
