摘要： A network device routes data packets by storing the packets in a switching memory as a function of a destination address of the packet. The switching memory comprises switching memory queues that are mapped to ports of the device. A header of a received packet is examined to determine the network destination address to which it is to be routed, and a destination queue is assigned to the packet based on the destination address. Thereafter, the packet is divided into cells, and the cells are written to contiguous locations in the destination queue.

摘要： A method for routing and switching data packets from one or more incoming links to one or more outgoing links of a router. The method comprises receiving a data packet from the incoming link, assigning at least one outgoing link to the data packet based on the destination address of the data packet, and after the assigning operation, storing the data packet in a switching memory based on the assigned outgoing link. The data packet extracted from the switching memory, and transmitted along the assigned outgoing link. The router may include a network processing unit having one or more systolic array pipelines for performing the assigning operation.
