摘要： A method and system for augmenting routing decisions in a network switching device with topology information acquired using source learning are disclosed. In the preferred embodiment, the method of selecting a port to transmit an outbound flow from a first node to a second node comprises the steps of identifying a plurality of ports associated with minimal equal-cost paths from the first node to the second node, and if an inbound flow from the second node is detected on a first port of the plurality of ports of the first node, then transmitting the outbound flow from the first port. In the absence of an inbound flow from the second node, the first node generally selects the port for the outbound flow from the plurality of minimal equal-cost paths. The present invention allows a switching device to take advantage of the path determination made at another router in the network while avoiding inconsistencies between conventional route selection operations and IP source learning in switching devices adapted to perform bridging on IP address.

摘要： The present invention resolves IP address conflicts in a network with DHCP or other address assignment protocol when some host on the network uses a conflicting static IP address to an IP address assigned to another host. The preferred method involves offering a given IP address to a host/node through the address assignment protocol while also detecting any other host/node using the offered IP address on a given VLAN using address resolution protocol. If another host/node is using the IP address, the offending host/node may be blocked on that VLAN for a set amount of time.

摘要： An exemplary method directs client devices client devices in a computing network to a remediation node. A subset of the client devices to receives remediation services is identified with a single common label. Upon determining that one of the client devices originating a communication request packet is identified by the single common label, processing the communication request packet by routing the communication request packet to a redirection server, and transmitting from the redirection server to the one client device a hypertext transfer protocol (HTTP) command specifying that the one client device redirect communications to the remediation node so that remediation services can be supplied to the one client device via the remediation node.

摘要： A method is provided for virtually partitioning policy space of traffic control equipment of a computer network. An operation is performed for creating a plurality of policy lists each including at least one policy. Each policy list is configured for influencing flow of a respective portion of traffic in a prescribed manner through the traffic control equipment. An operation is performed for assigning a unique identifier to each policy list and an operation is performed for assigning each portion of the traffic the unique identifier of one of the policy lists. Thereafter, an operation is performed for establishing within the policy space an association between each portion of the traffic and one of the policy lists dependent upon matching the assigned identifiers thereof whereby the flow of each portion of the traffic through the traffic control equipment is influenced by the associated policy list.

摘要： A multivariant, common basis classification method and apparatus for classifying protocol data units in a network switching device is disclosed. The method of classifying a protocol data unit (PDU) in the preferred embodiment includes the steps of generating a first string and a second string with which to characterize a PDU; mapping first and second strings into a first index and second index, respectively, where the first and second indices are selected from a plurality of indices; and selecting an instruction to apply to the PDU by matching the first and second indices. The plurality of strings are commonly generated from the source and destination address in the packet as well as other indicia with which to identify a traffic flow. The instructions specify how to classify, route, switch, or otherwise process the PDU.
