摘要： Techniques are described for synchronizing state information between a plurality of control units. A router, for example, is described that includes a primary control unit and a standby control unit. The primary control unit maintains router resources to ensure operation of the router. To ensure operation, the primary control unit receives state information from the router resources and maintains the state information for consumers, i.e. router resources that require or “consume” state information. Prior to updating the consumers with the state information, the primary control unit synchronizes the state information with the standby control unit. In the event the primary control unit fails, the standby control unit assumes control of the router resources. Upon assuming control, the standby control unit resumes updating the consumers with state information without having to “relearn” state information, e.g., by way of power cycling the router resources to a known state.

摘要： A bi-directional VLAN bridging path is created on an edge switch in an MVRP environment without administrator intervention using a virtual network profile (VNP) feature running on the edge switch. The VNP feature is configured to detect a device coupled to a port of the edge switch, learn the Medium Access Control (MAC) address of the device on a MVRP-VLAN and automatically convert the MVRP-VLAN to a VNP-Dynamic-VLAN corresponding to a static VLAN to create a bi-directional VLAN Port Association (VPA) for the device.

摘要： A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

摘要： A network infrastructure element such as a router or switch performs transparent and optimized validation of XML schemas of XML payloads received in the network element. The network element comprises logic for receiving and storing one or more validation scope rules that define a portion of an extensible markup language (XML) schema for validation; receiving and storing the XML schema; receiving over the network an application-layer message comprising one or more of the packets; identifying a particular XML element in an XML payload of the application-layer message, wherein the particular XML element is within the portion of the XML schema defined in the one or more validation scope rules; determining whether the particular XML element conforms to the XML schema; and performing a responsive action based on whether the particular XML element conforms to the XML schema.

摘要： A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element receives user-specified input that indicates a particular message classification. The network element also receives one or more data packets. Based on the data packets, the network element determines that an application layer message, which is collectively contained in payload portions of the data packets, matches the particular message classification. The network element processes at least a portion of the message by performing, on behalf of the application to which the message is directed, and relative to at least the portion of the message, one or more actions that are (a) specified in the user-specified input and (b) associated with the particular message classification.

摘要： Techniques are provided for performing security functions on a message payload in a network element. According to one aspect, a network element receives one or more data packets. The network element performs a security function on at least a portion of an application layer message that is contained in one or more payload portions of the one or more data packets. According to another aspect, a network element receives a first request that is destined for a first application. The network element sends, to a second application that sent the first request, a second request for authentication information. The network element receives the authentication information and determines whether the authentication information is valid. If the authentication information is not valid, then the network element prevents the first request from being sent to the first application.

摘要： A software system with task-specific flexible bindings that enhance the ability to dynamically add and remove resources from availability to tasks and that eliminates the need for coordination of globally unique names. The software system includes a task-specific name space which corresponds to a task executing in the software system. The task-specific name space holds flexible bindings each of which associates a task-specific name used by the task to refer to a desired resource or a set of one or more resources of the computer system and to information that describes the desired resource. The software system includes a resource mediator that obtains a message from the task. The resource mediator keeps information for each resource that identifies a resource handler task for the desired resource by resolving the task-specific name using the flexible binding.
