    摘要: A backplane interface adapter with error control and redundant fabric for a high-performance network switch. The error control may be provided by an administrative module that includes a level monitor, a stripe synchronization error detector, a flow controller, and a control character presence tracker. The redundant fabric transceiver of the backplane interface adapter improves the adapter's ability to properly and consistently receive receive narrow input cells carrying packets of data and output wide striped cells to a switching fabric.

    摘要: A backplane interface adapter for a network switch. The backplane interface adapter includes at least one receiver that receives input cells carrying packets of data; at least one cell generator that generates encoded cells which include the packets of data from the input cells; and at least one transmitter that transmits the generated cells to a switching fabric. The cell includes a destination slot identifier that identifies a slot of the switching fabric towards which the respective input cell is being sent. The generated cells include in-band control information.

    摘要: A switching fabric having cross points that process multiple stripes of serial data. Each cross point includes a plurality of port slices and ports. Each port includes a plurality of FIFOs, a FIFO read arbitrator, a multiplexer, a dispatcher, and an accumulator. In one embodiment, each cross point has eight ports and eight port slices. A method for processing a stripe of data at a cross point at one port slice includes storing data received from other port slices in a plurality of FIFOs and arbitrating the reading of the stored data. A step of writing data received from a port at the one port slice to an appropriate FIFO in a different port slice is also included. In one embodiment, a method for processing data in port slice based on wide cell encoding and an external flow control command is provided.
