Abstract:
A self routing cross-switch device comprising:a mesh interconnect providing high speed connections between a plurality input mesh connections and a plurality of output mesh connections; a plurality of input elements, each of said input elements including a switching element connected to said plurality of input mesh connections of said mesh interconnect, said switching element looking at a header of a frame arriving at the input element and configuring the switching element to route the frame though the mesh interconnect via one or more of said input mesh connections; a plurality of output elements connected to said mesh interconnect, each output element being connected to each said input element through said mesh via a respective input mesh connection, each of said output elements having a plurality of output first in first out (FIFO) devices for queuing frames arriving at the output element, each output first in first out device being associated with a separate one of said input elements; a local arbiter for dequeuing frames from each output first in first out device and sending frames to an output.
