  • Method and apparatus for processing packets in a routing switch
    Patent number: 6947415
    Abstract: A method, apparatus, and instructions for processing packets within a routing switch uses a multiprocessor architecture. The routing switch includes a switch fabric, a Routing Table Processing Unit, at least one packet buffer for queuing incoming and outgoing packets, at least one Packet Processing Unit, and a shared memory for storing a routing table. A Packet Processing Unit retrieves packets from a packet buffer memory, which may be a shared memory accessible to more than one of the Packet Processing Units depending upon the internal configuration of the components. The Packet Processing Unit categorizes the packets into routing information packets and data packets.
