Abstract:
A device for routing data packets between high-speed communication lines, comprising:a data interconnect circuit;a first processing node that receives data packets from a first high-speed communication line and is adapted to forward data packets via said data interconnect circuit;second and third processing nodes each adapted to receive data packets from said first processing node via said data interconnect circuit;first and second low-speed communication lines respectively coupled to said second and third processing nodes; anda multiplexer having at least two input ports, said multiplexer being adapted to send data packets over a second high-speed communication line, said sent data packets being received via said at least two input ports, said first and second low-speed communication lines being respectively coupled to said at least two input ports,said first, second, and third processing nodes being operative such that a first stream of data packets having a plurality of different sources and destinations are routed from said first high-speed communication line to said second high-speed communication line via a uniform distribution of said first and second low-speed communication lines, while a second stream of data packets each having the same source and destination are routed from said first high-speed communication line to said second high-speed communication line via only one of said first and second low-speed communication lines.
