摘要: A network device includes an input device configured to receive a data packet, where the input device includes a number of interfaces and the data packet includes a source address and a destination address. The network device also includes processing logic configured to generate forwarding information identifying a next hop for the data packet and determine whether an interface on which the data packet was received is a same interface on which the data packet is to be forwarded to the next hop. The processing logic is also configured to determine whether the data packet originated from a device that is part of a same subnet as the next hop.

摘要: A network device for performing redirect checking includes an input device and processing logic. The input device receives a data packet on a first one of a number of interfaces. The data packet includes source and destination addresses. The processing logic assigns an incoming interface to the data packet and generates forwarding information identifying a next hop for the data packet. The processing logic also identifies an outgoing interface based on the next hop and determines whether the incoming interface index is equal to the outgoing interface index. The processing logic also determines whether the data packet originated from a station that is part of the same subnet as the next hop. When both of these conditions are met, the processing logic generates a redirect message.

摘要: A router for switching data packets from a source to a destination in a network in which the router includes a distributed memory. The distributed memory includes two or more memory banks. Each memory bank is used for storing uniform portions of a data packet received from a source and linking information for each data packet to allow for the extraction of the uniform portions of a data packet from distributed locations in memory in proper order after a routing determination has been made by the router.

摘要: A method and apparatus for in-line processing a data packet while routing the packet through a router in a system transmitting data packets between a source and a destination over a network including the router. The method includes receiving the data packet and pre-processing layer header data for the data packet as the data packet is received and prior to transferring any portion of the data packet to packet memory. The data packet is thereafter stored in the packet memory. A routing through the router is determined including a next hop index describing the next connection in the network. The data packet is retrieved from the packet memory and a new layer header for the data packet is constructed from the next hop index while the data packet is being retrieved from memory. The new layer header is coupled to the data packet prior to transfer from the router.

摘要: A method and apparatus for switching a data packet between a source and destination in a network. The data packet includes a header portion and a data portion. The header portion includes routing information for the data packet. The method includes defining a data path in the router comprising a path through the router along which the data portion of the data packet travels and defining a control path comprising a path through the router along which routing information from the header portion travels. The method includes separating the data path and control path in the router such that the routing information can be separated from the data portion allowing for the separate processing of each in the router. The data portion can be stored in a global memory while routing decisions are made on the routing information in the control path.

摘要: A method and device for in-line processing a data packet is provided. The data packet is received at a first buffer. The data packet is divided into a number of cells that are stored in a first queue. For each cell, a cell state code is stored that indicates an address of the corresponding cell in the first queue and an indication of a sequence order of the cell within the data packet.
