<p>An optical interconnection network has a plurality of network nodes (70) interconnected by optical links (76-79). The network nodes (70) each receive a global clock and switch repeatedly with a fixed periodicity their routing states according to the global clock. Each network node (70) selects a time slot, a wavelength, and an initial optical link for transmitting a packet in dependence upon the desired path for the packet through the network, and outputs the packet in the selected time slot, wavelength and link. The network topology is a torus of the Manhattan street type. Each network node (70) comprises a plurality of channel nodes (73 a) for each link, a wavelength division demultiplexer (72a), a combiner (74a), and an optical space switch (75). The optical space switch (75) has a 2x2 configuration. The optical space switch (75) has a wavelength converter (42) per link feeding a passive wavelength routing device (41).</p> |
