424 results about "Distributed object" patented technology

In distributed computing, distributed objects are objects (in the sense of object-oriented programming) that are distributed across different address spaces, either in different processes on the same computer, or even in multiple computers connected via a network, but which work together by sharing data and invoking methods. This often involves location transparency, where remote objects appear the same as local objects. The main method of distributed object communication is with remote method invocation, generally by message-passing: one object sends a message to another object in a remote machine or process to perform some task. The results are sent back to the calling object.

Method and apparatus for accessing remote storage in a distributed storage cluster architecture

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.

Framework for providing quality of service requirements in a distributed object-oriented computer system

A system assures quality of service provided by a distributed network having at least one object. The system creates a contract that stores levels of quality of service offered by the network, determines a quality of service required by the object, and evaluates the contract to select a level of quality of service that corresponds to a current quality of service provided by the network. The system then compares the current quality of service to the required quality of service, and adjusts the current quality of service to obtain the required quality of service when the current quality of service fails to satisfy the required quality of service.

E-learning system and method

A control engine (12) downloaded by a server (1) to a student computer (2) instantiates panel objects (16) and multiple media objects (15) linked to each panel object (16). At any one time multiple media objects (15) operate simultaneously and in synchronism to generate multiple display and sound outputs for comprehensive learning output and student interaction. The media objects (15) operate autonomously, without even knowing their places in their respective hierarchies, thus allowing dynamic updates from the server (either server-driven or student-driven). Synchronization is achieved by the panel object activating the multiple relevant media objects for a panel and the media objects using time value attributes to control activation and termination times. The media objects access (84 )a stacking mechanism (82) in real time to determine a linked panel or media object to implement an operation in response to an event such as progression to a next panel. In addition to distributing objects in real time, the stacking mechanism (82) also dynamically modifies some objects by scripting or method invocation.

Communication between software elements

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.

Systems and Methods for Creating, Managing and Communicating Users and Applications on Spontaneous Area Networks

A Spontaneous Area Network (SPAN) is formed by mobile and fixed nodes using wireless transmission links between nodes, usually in a nearby geographical area. Applications allow users to create, join, leave, and manage SPANs and groups in a SPAN. Automatic procedures allow nodes to join other SPANs. Transmission power of the wireless network interface is dynamic, varying depending on battery level, type of information to transmit, state and topology of the network. A delay tolerant object layer abstraction creates, modifies, deletes, publishes, and handles Delay Tolerant Distributed Objects (DTDOs). A Patient Transport Protocol (PTP) ensures a reliable transport of information through the network while avoiding congestion conditions. An aggressive and explosive network protocol (AGENET) has routing and forwarding capacities and uses datagrams to establish communication between different nodes of the SPAN. Cooperation and diversity are exploited to react to node mobility that causes frequent changes in network topology and disconnections.

Method and System for Access Control in Distributed Object-Oriented Systems

A method and a system for accessing services provided by network resources in communication networks. Access to service capabilities is controlled at the application level by controlling the access through a gateway wherein an object-oriented service architecture based on abstracted application programming interfaces is implemented. Preferably, the service architecture is defined in OSA / Parlay standards. Access control is carried out by means of a logical entity, the service reference monitor, which is linked to the gateway and configured so that it intercepts all the communications passing between the client applications and the gateway. The service reference monitor captures the object reference to the service capability and assigns to the object reference a lifetime. At the expiration of the lifetime, the service reference monitor destroys the service capability. The probability of a malicious attack is lowered by limiting the time window of the life of access to a service.

Distributed object execution system

A distributed object execution system delegates the allocation and control of computing tasks to intelligent agent applications running on computing resources. User applications can invoke object methods associated with an application interface of the distributed object execution system. The system converts this method invocation into an available computing job with at least one computing tasks. The agents assess computing resources capabilities to perform available computing tasks. Based on these assessments, agents request jobs from a job server, which in turn assigns computing tasks to computing resources based on the job requests received. An agent instantiates a replica of the object and invokes a corresponding method on an associated computing resource. Upon completion of the invoked method, the user application is notified and provided with any method results. While an agent and associated computing resource is processing a method invocation, the user application can perform other activities.

Fast distributed object lookup for a computer network

A system and method related for performing lookup operations for objects distributed among different nodes in a peer-to-peer network are disclosed. Various nodes in the peer-to-peer network may store objects. Objects stored on a given node may be accessed by other nodes in the peer-to-peer network. To access an object, a node may first perform a lookup operation to determine where the object is stored, i.e., to determine which node in the peer-to-peer network stores the object. The peer-to-peer network may utilize a method to improve the performance of object lookup operations. In one embodiment, the method may allow object lookup operations to be performed with a latency on the order of one hop.

Performing object detection operations via a graphics processing unit

In one embodiment of the present invention, a graphics processing unit (GPU) is configured to detect an object in an image using a random forest classifier that includes multiple, identically structured decision trees. Notably, the application of each of the decision trees is independent of the application of the other decision trees. In operation, the GPU partitions the image into subsets of pixels, and associates an execution thread with each of the pixels in the subset of pixels. The GPU then causes each of the execution threads to apply the random forest classifier to the associated pixel, thereby determining a likelihood that the pixel corresponds to the object. Advantageously, such a distributed approach to object detection more fully leverages the parallel architecture of the PPU than conventional approaches. In particular, the PPU performs object detection more efficiently using the random forest classifier than using a cascaded classifier.
