Abstract: Methods, systems, and computer program products are disclosed for provisioning software resources used with aggregated web services. The disclosed techniques enable heterogeneous identity systems to be joined in the dynamic, run-time web services integration environment. Authentication and authorization may now be performed for the aggregated service, as well as for its sub-services. SOAP (“Simple Object Access Protocol”) messages, as an example, may be used to relay identity information among distributed services, whereby credentials may be specified in the SOAP message header to accompany a service request specified in the SOAP message body.

Abstract: Enforcing data policy using style sheet processing. A Document Type Definition (DTD) associated with an Extensible Markup Language document is modified to specify a reference to stored data policy to be applied to document elements. Each data element may specify a different data policy. This technique uses minimal network transmission overhead, as the policy itself is not transmitted through the network until the DTD reaches the node where the data policy will be applied. Programming code implementing the data policy is then retrieved, using the references, by an Extensible Stylesheet Language (XSL) processor instrumented according to the present invention. Data policy is preferably enforced by overriding the existing XSL “value-of” method. DTD information describing a document element may be suppressed from a DTD being generated for the output document of the data policy enforcement process, providing privacy protection for the details of the associated policy.

Abstract: A system and method for selectively handling requests for dynamic data processing. In the system and method, requests for dynamic data processing can be received in an origin server, but the dynamic data processing can be deferred to an edge server in those circumstances where it is dynamically determined that the edge server is capable of performing such dynamic data processing. In this way, network transmission latencies can be avoided by performing dynamic data processing in those edge servers closest to the requesting user.

Abstract: Methods, systems, and computer program products are disclosed for dynamically integrating software resources (such as web services and other back-end software resources) using the services of a content framework (such as a portal platform). A portlet model is leveraged to allow programmatic portlets to serve as proxies for web services, thereby extending portlets beyond their traditional visual role. A deployment interface and a system interface are described for these portlet proxies. The deployment interface is used for composing new web services, and a composition tool is described. The system interface allows for run-time management of the web services by the portal platform. The service provider for a particular function may be bound to the portlet proxy at development time or at run-time.

Abstract: Methods, systems and computer program products for management of application programs on a network including a server supporting client stations are provided. The server provides applications on-demand to a user logging in to a client supported by the server. Mobility is provided to the user and hardware portability is provided by establishing a user desktop interface responsive to a login request which presents to the user a desktop screen through a web browser interface which accesses and downloads selected application programs from the server responsive to a request from the user on the user desktop screen at the client. The application program is then provided from the server and executed at the client. The application program may further be customized to conform to the user's preferences and may also provide for license use management by determining license availability before initiating execution of the application program.

Abstract: Methods, systems, and computer program products for improving network operations by dynamically redeploying services (such as web services or other network-accessible services) in a computing network. A programmatic replication or redeployment process is defined, whereby system upgrades may be implemented by redeploying services dynamically, without human intervention, enabling the complexity of upgrading previously-deployed software to be reduced significantly.

Abstract: Methods, systems, and computer program products for improving network operations by dynamically deploying services (such as web services or other network-accessible services) in a computing network. A process is defined whereby conditions such as usage metrics for incoming client requests (or other network conditions such as load balancing considerations) are monitored, and used to trigger dynamic deployment of web services to locations in the network in order to improve efficiency (e.g. by reducing response time to the client and/or reducing the burden on the back-end computing system resources). Service requests are dynamically routed to the destination where the service resides, in a manner which is transparent to the client. In an optional aspect, programmatic replication of system upgrades may be implemented by redeploying services using this same dynamic deployment approach, enabling the complexity of upgrading previously-deployed software to be reduced significantly.

Abstract: Methods, systems, and computer program products for improving network operations by dynamically undeploying services (such as web services or other network-accessible services) in a computing network. A process is defined whereby conditions such as usage metrics for incoming client requests (or other network conditions such as load balancing considerations) are monitored, and used to trigger dynamic undeployment of web services from locations in the network. The undeployment may apply to distributed locations of a service, and may also apply to an origin server from which the service was originally deployed. Service requests are dynamically routed to the destination where the service resides, in a manner which is transparent to the client.

Abstract: Management of configurable applications programs on a network is provided by using two program files for each configurable application program. The two program files are provided to a network server station which operates as the on-demand server for software deployment and may also act as the application server. The on-demand server makes the first (configuration manager) program available to an administrator to obtain preferences for the configurable preferences of the application program which have been designated as administrator preferences. The on-demand server also provides a second (application launcher) program to its client stations. The application launcher program not only provides for a user interface to execute the application program itself but also allows a user to specify one or more of the configurable parameters of the application program. An icon is displayed on the screen of the client station through which a user may initiate execution of the application program.

Abstract: A processor functioning as a coprocessor attached to a central processing complex provides efficient execution of the functions required for database processing: sorting, merging, joining, searching and manipulating fields in a host memory system. The specialized functional units: a memory interface and field extractor/assembler, a Predicate Evaluator, a combined sort/merge/join unit, a hasher, and a microcoded control processor, are all centered around a partitioned Working Store. Each functional unit is pipelined and optimized according to the function it performs, and executes its portion of the query efficiently. All functional units execute simultaneously under the control processor to achieve the desired results. Many different database functions can be performed by chaining simple operations together. The processor can effectively replace the CPU bound portions of complex database operations with functions that run at the maximum memory access rate improving performance on complex queries.

Abstract: A video distribution management system utilizes a shared video library and a wide area network to deliver video files to local caches on the local area networks serving a subset of local viewing stations. A combination of direct local cache access, scheduled future local cache access and speed match distribution of video files makes the overall system both efficient and economical. In particular, a locally stored preface of a video file can be immediately viewed on the local area network while the balance of the video file is transmitted from the remote video library.
