Abstract
A self routing cross-switch device and method is provided with a mesh interconnect having high speed connections (e.g., connections at 10 Gbps). A plurality of input MUX elements are connected to the mesh interconnect. Each MUX element looks at a header of a frame arriving at the input MUX and configures the MUX element to route the frame though the mesh. A plurality of memory output devices are connected to the mesh interconnect. Each output device has a plurality of output first in first out (FIFO) devices for queuing frames arriving at the output memory. Each output first in first out device is associated with one input MUX. A local arbiter is provided for dequeuing frames from each output first in first out device and sending frames to an output.
