Abstract
A router includes a plurality of virtual networks, a plurality of output links, at least one decoder and arbitration circuitry. Each virtual network has a plurality of virtual network inputs and a plurality of virtual network outputs. Each virtual network output is associated with an output link. The decoder decodes a header of a data unit received on a virtual network of one of the virtual network inputs. The decoder generates a first request and a second request. The first request is for the allocation of a virtual network output of the virtual network to the virtual network input. The second request is for the allocation of an output link associated with the virtual network output to the virtual network output. The arbitration circuitry performs arbitration of the first request and arbitration of the second request in parallel.
