Abstract
A method of data switching. Data is received by at least one input port of a crosspoint switch. The crosspoint switch configurably casts the data to at least one output port of the crosspoint switch. Each output port of the crosspoint switch is connected to a respective input of a logic function device such as an FPGA. The logic function device applies a logic function to data received from each output port of the crosspoint switch, such as address filtering or multiplexing, and outputs processed data to one or more respective logic function device output interfaces. Also, a method of switching involving circuit switching received data to an output while also copying the data to a higher layer function.
