Abstract:
1. A switching fabric to transmit received data frames to destinations, each received data frame to specify a destination, the switching fabric comprising: a plurality of input ports, each input port to include a data frame queue associated with the specified destination in each received data frame each input port to partition each received data frame into data cells, the input port to queue the data cells in the data frame queue associated with the specified destination; a plurality of crossbar sections, each crossbar section coupled to each input port to receive the data cells at cell transfer intervals on a data link coupled between each input port and each crossbar section, each crossbar section to include a destination queue associated with the specified destination in each received data frame; and a plurality of output ports, each output port to receive data cells from the crossbar section on a data link between each crossbar section and each output port; wherein each input port includes logic to schedule the transmission of each data cell of a received data frame to any output port associated with the specified destination, the schedule based upon a crossbar section indicating an ability to receive a data cell at a destination queue associated with the specified destination at a subsequent cell transfer interval.
