摘要： A packet routing apparatus has a plurality of routing units, connected by a first connecting mechanism. The plurality of routing units comprise a first routing unit, connected to at least one port, and a second routing unit, connected to an extended function processor. The first routing unit transmits a packet, received from the port, to another first routing unit and/or a second routing unit. The second routing unit transmits the packet, received from the first connecting mechanism, to the extended function processor.

摘要： A routing apparatus includes a plurality of routing units and function units. The routing unit receives a packet from each port, and uses header information contained in the packet to judge whether the packet should be transmitted to the function unit. In the case where the packet should be transmitted to the function unit, the routing unit adds a first identifier to the packet and transmits it to a transmission unit. The function unit receives the packet containing the first identifier from the transmission unit, and executes a predetermined processing for the packet. The function unit adds a second identifier to the packet and transmits it to the transmission unit.

摘要： There is provided a packet routing apparatus for performing an IP additional function processing for a packet in the middle of a packet routing processing without damaging the high speed characteristic of the packet routing processing. A unique address is determined for each of function accelerators 11 to 14 in the inside of an extended function module 6, the unique address is added to a packet by a physical address lookup unit 105, and a data distribution unit 112 distributes the packet to the function accelerator corresponding to the unique address.
