    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 apparatus includes a checking functionality (CF) for processing data packets in a computer network that comprises a plurality of CFs. The CF includes an interface for communication with one or more source switches that route data packets to the CF for processing, a packet processing capability for processing the data packets, and logic for communicating data regarding the packet processing capability to the source switch through the interface.

    摘要: Systems, devices, and methods, including executable instructions are provided for resolving content addressable memory (CAM) match address priority. One method includes retaining a first match address as the best match address. Subsequent match addresses are compared to the retained best match address, each match address being associated with a compare cycle during which a selected columnar portion of each CAM entry is compared to a corresponding portion of a search term. The best match address is updated as a result of the comparison.

    摘要: A network, network devices, and methods are described for packet processing indication. A method includes tunneling a packet from a first network device to a second network device associated with a first checking functionality. The second network device has an address different than an original destination address of the packet. The method also includes return-tunneling the packet from the second network device to the first network device with an indication of whether the packet was processed by the first checking functionality. The method includes tunneling the packet from the first network device to a third network device associated with a second checking functionality in response to the indication being that the packet was not processed by the first checking functionality. The third network device has an address different from the original destination address of the packet.

    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.

    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.
