摘要： A network element such as a router or switch provides application-level quality of service for application-layer messages processed in the network element, using application QoS logic which when executed by the one or more processors is operable to cause receiving an application-layer message; matching one or more attributes of the application-layer message to the message classification rules; determining a message classification of the application-layer message based on the matching; selecting one of the network-level QoS values using the mapping and based on the determined message classification; and marking a network-level header of the application-layer message using the selected QoS value. As a result, attributes of application messages at OSI Layer 5, 6, or 7 can be used to determine how to mark packets of the messages with QoS values at OSI Layer 2, 3 or 4, integrating application-level concepts of order and priority into network-layer QoS mechanisms.

摘要： A method is disclosed for performing message and transformation adapter functions in a network element on behalf of an application. According to one aspect, the network element determines an application layer message that is collectively contained in payload portions of data packets. The application layer message conforms to an application layer protocol, such as Hypertext Transfer Protocol (HTTP). The network element determines the application layer protocol to which the application layer message conforms. Based on the application layer protocol, an adapter is selected from among a plurality of adapters that are accessible to the network element. The application layer message is provided to the selected adapter, which converts the application layer message into a “canonical” message that is not specific to any particular application layer protocol.

摘要： A method is disclosed for application layer message-based network element management of server failures. According to one aspect, a network element such as a router intercepts session state information that is contained in a request from a client and locally stores the session state information. As a result, application servers to which the requests are directed do not need to store the session state information. If an application server fails, then the network element can use the session state information stored at the network element to continue the session with another application server, transparently to the client application that is involved in the session.

摘要： A method is disclosed for protecting a network against a denial-of-service attack by inspecting application layer messages at a network element. According to one aspect, when a network element intercepts data packets that contain an application layer message, the network element constructs the message from the payload portions of the packets. The network element determines whether the message satisfies specified criteria. The criteria may indicate characteristics of messages that are suspected to be involved in a denial-of-service attack, for example. If the message satisfies the specified criteria, then the network element prevents the data packets that contain the message from being received by the application for which the message was intended. The network element may accomplish this by dropping the packets, for example. As a result, the application's host does not waste processing resources on messages whose only purpose might be to deluge and overwhelm the application.

摘要： A method is disclosed for generating a network topology representation based on inspection of application messages at a network device. According to one aspect, a network device receives a request packet, routes the packet to the destination, and extracts and stores correlation information from a copy of the request packet. When the network device receives a response packet, it examines the contents of a copy of the response packet using context-based correlation rules and matches the response packet with the appropriate stored request packet correlation information. It analyzes recorded correlation information to determine application-to-application mapping and calculate application response times. Another embodiment inserts custom headers that contain information used to match a response packet with a request packet into request packets.
