摘要： Methods, systems and computer program products are provided for type of service classification of a communication request for an application executing on a server. An application plug-in associated with the application is provided in an operating system kernel of the server. The application plug-in receives the communication request and obtains application level information from the received communication request. The application plug-in further assigns a type of service classification to the received communication request based on the obtained application level information and provides the assigned type of service classification information for the communication request to a process executing on the server for processing communications from the server responsive to the communication request.

摘要： Methods, systems, and computer program products for dynamically modifying an application program's behavior in response to changing environmental conditions (such as network changes, system changes, and so forth). The application may solicit such information, and/or may receive unsolicited environmental change notifications. In response to a change notification, the application may take one or more of the following approaches to adapt to the changing conditions: (1) alter its execution; (2) modify its use of, or control of, other cooperating application; and (3) modify the selection of application execution threads. (An application might also decide to make no changes in its behavior.)

摘要： Methods, systems and computer program products are provided for providing transactional quality of service providing transaction service level information from an application requesting a data transmission transaction to a communication process executing on a data processing system. The transaction service level information is provided separate from the data for the data transmission transaction. A quality of service level associated with the data transmission transaction is determined based on the transaction service level information received from the application. Other embodiments also provide for establishing a quality of service level without reference to transaction data content while further embodiments provide for establishing a quality of service level for responses.

摘要： Methods, systems and computer program products are provided for transferring a Transmission Control Protocol (TCP) connection with a client device between data processing systems in a cluster of data processing systems. An operating system kernel of a first data processing system obtains application level information from a transaction received from the client over the connection. In addition, application state information associated with the connection may be obtained from the first application. A second application at a second data processing system is selected for transfer of the connection based on the obtained information and the connection is transferred to the second data processing system. The transfer includes providing to the second data processing system the associated state information of the first communication protocol stack and, optionally, the obtained application state information associated with the connection from the first application. Selection operations for transfers may be initiated responsive to a notification from the first application of completion of a transaction.

摘要： A system and method for monitoring liveliness includes a management device which has an application layer where applications are executed. A connection monitor is located other than on the application layer, and the connection monitor is configured to receive requests from clients and deliver the requests to components on the application layer. The components include a generic application monitor which responds to liveliness monitor requests from the clients for all applications monitored, and one or more applications which response to requests to that application.

摘要： A fast policy classification method and system. A policy differentiator can be provided which can include a policy repository configured to store hierarchical policy classification trees. The policy differentiator further can include a hashing module configured to produce integer values for string based selector attributes. In one aspect of the invention, the hashing module can include a longest string hashing function. A policy matching engine can be provided which is configured to locate policy rules in the hierarchical policy classification trees according to the integer values produced for the string based selector attributes. Finally, a policy matching engine interface can be provided through which policy queries and resulting policy decisions of the policy matching engine can be communicated between the policy matching engine and the policy enforcement entity.

摘要： Techniques are disclosed that enable an application to prioritize its traffic in an application-specific manner, such that traffic which is most important to this application can be prioritized over traffic that is less important to this application, where this prioritization information is reflected in differential treatment of the traffic within the network. An application conveys relative priority information for its traffic to a Web proxy or edge server, and this device then consults stored policy information to determine how the traffic should be prioritized in the network. The Web proxy also ensures that usage of network resources is balanced among multiple applications. Cookies are used for transmitting priority information between the edge server and application in an efficient manner.
