Abstract: A system, method and program stores, in a local cache, only a small part of a large file that is being requested over a network such as the Internet. In a preferred embodiment, the caching agent starts transferring this partial file to the client while it is simultaneously retrieving the remaining portion of the file across the Internet. A preferred embodiment of the invention stores a first page of the browser display in the cache. Other embodiments store more than the first page, or a part of the full file or document, thereby creating a safety margin in storing more than one page. Another preferred embodiment initially stores the full file or document, and if there is a need for cache replacement, the cache is replaced up until the first page is reached. As such, the cache space requirements are minimized for large documents being retrieved over the World Wide Web.

Abstract: Resilient members absorb vibrations to limit transmission of vibrations from a chassis to a base of a disk record/playback device. A restricting device limits transverse movement of the base on the resilient members. The restricting device limits sloping of a disk mounted on the record/playback device, and thereby prevents interference of the mounted disk with other disks in a storage device. By minimizing the sloping of the disk, the minimum required clearance from the disk mounted on the turntable is reduced and the available vertical space for use in storing disks is maximized. A compact design is possible permitting conformity to constrained dimensions such as standard DIN dimensions in vehicles.

Abstract: A system and method for balancing loads in a computer system is disclosed. The system and method assess the health of various paths in a computer system by determining the health or status of at least two layers on each path. A health or status of the paths is then determined based on the information of the health of each layer in the path. A load balancing device routes information for processing to the various paths based on the determined health of the paths. To better estimate the health of a path, algorithms which weight the health signals for each layer are used giving greater weight to layers of greater importance. The system and method can also add or remove additional paths if the combined health of the existing paths is determined to be above or below a predetermined value. In addition, the weight of certain layers can be locked in to provide for updating of specific layers.

Once the message is received by the receiving system, the message is then translated based on the shared format.

Abstract: Efficient assembly and transmission of information to multiple receivers and efficient acquisition of information from multiple sources over a shared communication channel is provided. An adaptive fuzzy control system prioritizes files for broadcast delivery or acquisition. Files are assigned a degree of membership in fuzzy variables and mapped onto a multi-dimensional control surface to determine which files should be sent or acquired first. Each of the fuzzy variables is divided into sets wherein a particular file can be a member of more than one set at varying degrees. The control surface is periodically reshaped to adapt in a dynamic environment, thereby converging on the optimal solution for the current conditions.

Abstract: Provided herein is a name service that includes published data that is associated with one or more duration entities and one or more modification entities, enabling the name service to more efficiently manage access to published data. To publish data, a publishing client transmits a publication request to a name service. The publication request may specify a modification entity and a duration entity. The name service creates at least one name entry that associates the published data with the modification entity and the duration entity. There are several requests to modify or depublish published data that a name service will honor only when they originate from a modification entity. These are (1) requests to modify published data, and (2) requests to depublish published data. A name service depublishes published data based on the termination of the duration entity that is associated with the published data, when, for example, a garbage collector detects that the duration of an entity has ended.

Abstract: The distributed network application management system provides distributed data processing services in a data communication network environment. This system dynamically allocates resources to a processing request that is received from a user application device that has limited processing capabilities using application modules that are machine-independent and network independent to thereby process the received request in the network, yet in a manner that appears to be implemented on the user application device. The distributed network application management system is implemented in a network environment using a kernel that represents the network protocol and the effective processor is dynamically created in the network as capacity becomes available. The applications in this system are distributed via the network without meta code being written for the application.
