Abstract

A system is disclosed for routing data cells from at least one of a plurality of source port processors to at least one destination port processor. Such a system contemplates each cell comprising a plurality of cell frame portions. In a preferred embodiment of the system of the present invention, each cell generated by the at least one source port processor is separated into its constituent frame portions. Each frame portion has associated therewith a first characteristic and a second characteristic. The cell portions are transmitted to at least one port associated with at least one crossbar chip. The at least one port is in communication with at least two of the plurality of source port processors. Each cell portion is selectively transmitted according to its first characteristic to a corresponding one of the crossbar chips. Each cell portion is selectively transmitted according to its second characteristic to a corresponding one of the ports of the corresponding one of the crossbar chips. Each cell portion is selectively redirected according to its second characteristic to a corresponding one of the ports. Each cell portion is transmitted to a corresponding one of the at least one destination port processors.
