    摘要: An embodiment of the invention evaluates the suitability of routes for use in a network route cache. An embodiment of the invention allows the use of network routing caches to be optimized such that routes that are not used to route to a large number of destinations can be offloaded into a less expensive host route cache.

    摘要: An example method includes creating a plurality of redundant, non-looping paths to a plurality of switches, and providing information to the plurality of switches about the plurality of redundant, non-looping paths. The method further comprises assigning each of a plurality of clients to one of the plurality of redundant, non-looping paths, and providing information to the plurality of switches about which of the plurality of redundant, non-looping paths each client of the plurality of clients is assigned to. Then, in response to receiving a packet from a client of the plurality of clients, the method comprises transmitting the packet on one of the plurality of redundant, non-looping paths to one of the plurality of switches based at least in part on which of the plurality of redundant, non-looping paths the client is assigned to.

    摘要: A method includes reading content of network traffic that arrives at a network port of a network switch of a mesh of network switches. A hash algorithm is applied to the read content to indicate a path to a destination network switch of the mesh, the hash algorithm being common to all network switches of the mesh. The network traffic is forwarded via a network port that is associated with the indicated path.

    摘要: One embodiment disclosed relates to a method for remote mirroring of network traffic. A data packet to be remotely mirrored is received by an entry device. The entry device is pre-configured with a destination Internet Protocol (IP) address to which to mirror the data packet. An IP header is generated and added to IP encapsulate the data packet. The IP header includes the aforementioned destination IP address. The IP-encapsulated packet is forwarded to an exit device associated with the destination IP address. Subsequently, the exit device may decapsulate the IP-encapsulated packet to reproduce the original data packet.

    摘要: One embodiment disclosed relates to a method for mirroring of select network traffic. A data packet is received by a network device. A determination is made as to whether a designated aspect of the packet matches a flagged entry in a look-up table on the network device. If a match is found, then copy of the packet is sent to an associated mirror destination. Another embodiment disclosed relates to a networking apparatus. The apparatus includes at least an operating system, a look-up table, and a mirroring engine. The operating system includes routines utilized to control the apparatus, and the look-up table includes selection information for mirror sources. The mirroring engine forwards copies of selected packets to a corresponding mirror destination. Another embodiment disclosed relates to a method of selecting packets to mirror that includes checking state information relating to the network traffic against dynamic mirroring criteria.

    摘要: A system for performing an input processing function on a data packet. The system has an input port to which a first processor is coupled, which determines an attribute of the data packet, and a memory coupled to the first processor having a number of queues. The data packet is assigned to one of the queues based upon the attribute determined, which may be an indicator of a priority characterizing said data packet. Input processing is thus performed in a fixed amount of time, deferring variable latency operations until after the input memory.

    摘要: A method for testing a network device having modules for receiving and sending data packets in a network includes generating in the network device at least one internal data structure associated with a data packet received by the network device from the network. A predefined action on the network device is then preformed responsive to the internal data structure indicating that the data packet satisfies a predefined condition.
