Abstract: A data re-direction method can include receiving a data re-direction request from an application server; identifying from the data re-direction request at least one data re-direction primitive, the primitive including at least one data element selected from the group consisting of a client identity and a client type; retrieving personalized data according to subsequent client data requests associated with the at least one data re-direction primitive; and, forwarding the retrieved personalized data directly to a POC corresponding to the client data requests without first passing the retrieved personalized data through the application server.

Abstract: Embodiments of the present invention include methods, systems and computer program products which provide for a complex policy rule structured in a plurality of levels wherein the complex policy rule selects an action for execution based on a plurality of individual policy conditions. An event is received having an associated value defining a point in a space covered by the individual policy conditions. The following operations are performed if the complex policy rule is a CNF policy rule. A plurality of summary conditions are generated, each of the summary conditions being associated with one of the levels. The associated value of the received event is compared to a selected one of the summary conditions to determine if the selected one of the summary conditions is met.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The method and apparatus of the present invention may be utilized to interconnect multiple local area networks to a data processing network including both multiple network nodes having routing and functional capability within the data processing network and multiple endpoint nodes having only local address capability, while minimizing the amount of routing information which must be maintained within the data processing network. A concentrator node is established for interconnection between each of the multiple local area networks and the data processing network. The concentrator node includes a network node interface having routing and functional capability for an associated local area network and an endpoint node interface having local address capability.

Abstract: A method, apparatus, and computer implemented instructions for managing traffic in a network data processing system. Traffic for a plurality of network paths is monitored. In response a packet for a particular network path within the plurality of network paths causing traffic for the particular network path to exceed a level of traffic allowed, an amount of available bandwidth is reduced based on a fair share for the particular network path.

Abstract: 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.
