A network storage system includes a virtual file system (“VFS”) that manages the files of the network storage system, and a storage center that stores the files. The VFS and the storage center are separated, such that a client accesses the VFS to conduct file system operations and the client accesses the storage center to upload / download files. The client accesses the network storage system through one or more storage ports. The storage center includes a plurality of distributed object storage managers (DOSMs) and a storage cluster that includes a plurality of intelligent storage nodes. The network storage system includes additional storage centers at geographically disparate locations. The network storage system uses a multi-cast protocol to maintain file information at the DOSMs regarding files stored in the intelligent storage nodes, including files stored in disparate storage centers.

An improved system and method for flexible object placement and soft-state indexing of objects in a distributed object store is provided. A distributed object store may be provided by a large number of system nodes operably coupled to a network. A system node provided may include an access module for communicating with a client, an index module for building an index of a replicated data object, a data module for storing a data object on a computer readable medium, and a membership and routing module for detecting the configuration of operable nodes in the distributed system. Upon failure of an index node, the failure may be detected at other nodes, including those nodes that store the replicas of the object. These nodes may then send new index rebuilding requests to a different node that may rebuild the index for servicing any access request to the object.

One embodiment of the present invention provides a distributed, differential electronic-data storage system that includes client computers, component data-storage systems, and a routing component. Client computers direct data objects to component data-storage systems within the distributed, differential electronic-data storage system. Component data-storage systems provide data storage for the distributed, differential electronic-data storage system. The routing component directs data objects, received from the clients computers, through logical bins to component data-storage systems by a compression-enhancing routing method.

It will be well known that a so-called object-oriented approach to computer programming has become widespread over the past few years and applications such as large multiplayer games are no exception. A number of approaches to allowing objects to communicate with one another have been developed. One set of these approaches relate to allowing so-called distributed objects, which is to say objects distributed over a client / server system, to communicate with one another. With reference to applications such as large multiplayer games, dynamic real time distributed communications between mobile objects must be considered. Present day techniques, involving the use of simple TCP / IP or UDP / IP, CORBA or DCOM are unable to provide such real time dynamic performance. According to one aspect of the invention a method of providing communication between two or more application software elements is provided comprising associating each application software element with a communication software element through which to send and / or receive messages, holding the communication state of the associated application software element in each communication software element, allowing each application software element to communicate with other application software elements by sending and receiving messages through the respectively associated communication software elements and allowing each application software element and associated communication software element to move. Holding the communication state in the communication software element associated with each application software element allows the application software element and communication software element assembly to communicate and move in particularly dynamic fashion. Messaging consequently enabled, carried out on a per software element basis, allows for continuity of communication between objects even if they move in a dynamic fashion.

A method for updating a set of presentation images through a single-buffered multipoint dispatcher over a network to multiple clients is provided. Each screen of a set of screens included in the presentation is divided into tiles. Packets respectively corresponding to the tiles of a first screen are stored in a single buffered multipoint dispatcher according to a time sorted hierarchy, a top packet having a most recent time value and a bottom packet having a least recent time value. Each tile of the first screen is compared with a corresponding tile of a second screen to identify any non-matching tile pairs. For each non-matching tile of the second screen, a packet corresponding to that non-matching tile is provided to the single buffered multipoint dispatcher. Then, non-matching tiles of the first screen are replaced with the respective non-matching tiles of the second screen, while maintaining the time sorted hierarchy. Such replacement supports clients with different connection speeds at different frame rates.

An external object model is built into a comprehensive, drag-and-drop, dynamic, distributed object model, to offer its users lower total cost of ownership than do conventional user interface applications and application builders. A Windows® workstation user computer is provided with a quick, simple, easily-managed path to combinations of available applications on a network of systems, in such a way that the user can establish and exploit complex data relationships and software capabilities on the workstation without application installation, significant access effort, or specialized knowledge. Runtime binding prepares and links user forms and reports to application programs as desired, without preparatory steps. The definition and use of query objects to view concurrently multiple database tables offers the unique ability to combine fields from dissimilar database engines into a single view.

A distributed active knowledge and process base incorporates multiple Distributed Object Technology Systems (DOTS) connected over a network, the Internet, or wireless media to allow multiple types of data, processes, and services (system elements) to be created and modified within the same collaborative framework, and thereby permits data to be appropriately mapped to said processes, provides and updates periodically knowledge about available system elements and their values, allows separate systems to negotiate multiple forms of collaboration, and contains sufficiently flexible levels of data security in order to foster online collaboration.
