    • An ATM data network switch having two separate but simultaneously active switch fabrics and a plurality of slot controllers is disclosed. Each slot controller has at least one external data link thereto and is separately connected to the two separate switch fabrics. Each switch fabric was the ability to switch a data cell transmitted from any one of the slot controllers to any of the other slot controllers. Each slot controller is arranged to determine the availability of the data paths to all the other slot controllers through both switch fabrics and to select for each cell to be switched a data path through one or the other of the switch fabric according to the availability determined.

    • An ATM network switch is provided with a switch fabric linking a plurality of slot controllers. Each slot controller receives ATM cells from an external data link and has at least one input port to the switch fabric. The switch fabric switches a data cell received from any one port to one or more other ports. Each slot controller is provided with a separate group of buffers for each slot controller in the switch, and stores ATM cells intended for those other slot controller in the buffers. Each group of buffers includes a separate buffer for each class of cell traffic, so that the ATM cells are stored by intended slot controller and by class. The slot controller also includes a buffer control circuit which controls the passing of cells from the buffer to the switch fabric. The switch fabric includes input FIFOs, an indication of the fullness of which is measured and signaled back to the buffer control circuit. In response to the feedback signal which is an indication of the congestion level of each switching path through the switch fabric from one port thereto to another, the buffer control circuit controls the output of cells from the slot controller buffers to the switch.
    • ATM网络交换机设置有连接多个时隙控制器的交换结构。 每个时隙控制器从外部数据链路接收ATM信元,并且具有至少一个到交换结构的输入端口。 交换结构将从任何一个端口接收的数据信元切换到一个或多个其他端口。 每个时隙控制器为交换机中的每个时隙控制器提供单独的缓冲器组,并且将用于那些其他时隙控制器的ATM信元存储在缓冲器中。 每组缓冲器包括用于每类单元流量的单独缓冲器,使得ATM单元由预定的时隙控制器和按类存储。 时隙控制器还包括缓冲器控制电路,其控制从缓冲器到交换结构的单元的传递。 交换结构包括输入FIFO,其充满度的指示被测量并发送回缓冲器控制电路。 响应于反馈信号,其是通过交换结构从一个端口到另一个端口的每个交换路径的拥塞级别的指示,缓冲器控制电路控制从时隙控制器缓冲器到交换机的小区的输出。
