  • System and method for switching packets in a network
    Patent number: 6434115
    Abstract: A switching node for transferring packets, each including a destination address, in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module is connected to a communication link for receiving packets thereover, and each output port module is connected to a communication link for transmitting packets thereover. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet therefor identifying the output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor.

  • Packet forwarding apparatus and method using pipelined node address processing
    Patent number: 6421342
    Abstract: An apparatus and method for forwarding packets of data across a switching node on a network are disclosed. A packet of data to be forwarded includes a destination address, which can be partitioned into a plurality of subaddress fields. To improve speed of packet forwarding, destination addresses are processed in a pipelined fashion. To that end, the system includes a plurality of pipelined subaddress processors which process a respective plurality of subaddress fields of the destination addresses. Addresses are received during addressing intervals. During a first interval, a first subaddress of a first packet is processed by a first subaddress processor. During a next interval, a second subaddress processor processes a second subaddress field of the first packet destination address while the first subaddress processor processes the first subaddress field of a destination address of a next packet.
