Abstract: A computer implemented Virtual Sensor Object includes an abstract class of Objects, and an actual software instantiation of which performs an abstract observation, evaluation, and expression method in either a static, a synchronous, or an asynchronous Form. The evaluation method of the Virtual Sensor Object allows the substantive meaning of the observations to be expressed in a Form which clarifies the Substance of the observations, so that the substantive meaning of the observations may be perceived directly, with little or no cognitive interpretation being required. The methods of expression and evaluation are dependent on the observation, whereas they are independent as to how they use and express meaning.

Abstract: A computer network server using HTTP (Web) server software combined with foreground view composer software, background view composer software, a view tile cache, view tile cache garbage collector software, and image files provides image view data to client workstations using graphical Web browsers to display the view of an image from the server. Problems with specialized client workstation image view software are eliminated by using the Internet and industry standards-based graphical Web browsers for the client software. Network and system performance problems that previously existed when accessing large image files from a network file server are eliminated by tiling the image view so that computation and transmission of the view data can be done in an incremental fashion. The view tiles are cached on the client workstation to further reduce network traffic. View tiles are cached on the server to reduce the amount of view tile computation and to increase responsiveness of the image view server.

Abstract: A system and method for page replication in a non-uniform memory access system (NUMA). The system and method generates replicas for memory objects to reduce contention and improve overall system performance in NUMA multi-processor computer systems. Memory objects are used by the operating system to represent files, and comprise a state portion and a page cache portion. The state portion describes the state of the memory object. The page cache portion contains a set of physical memory pages that are currently being used to hold data belonging to the memory object. When a thread accesses data associated with a particular memory object for the first time, a check is made to determine if physical memory had already been allocated for the requested memory page. If a memory page is found, the memory object is interrogated to determine if the memory page is within a predetermined topological distance from the requesting node.

Abstract: A system and method are disclosed that provides transparent, global access to devices on a computer cluster. The present system generates unique device type (dev.sub.-- t) values for all devices and corresponding links between a global file system and the dev.sub.-- t values. The file system is modified to take advantage of this framework so that, when a user requests that a particular device, identified by its logical name, be opened, an operating system kernel queries the file system to determine that device's dev.sub.-- t value and then queries the a device configuration system (DCS) for the location (node) and identification (local address) of a device with that dev.sub.-- t value. Once it has received the device's location and identification, the kernel issues an open request to the host node for the device identified by the DCS.

Thereafter, the controller exchanges data streams, herein IBM 5250 data streams, between the server and the client.

Abstract: There is described a personal conferencing method and system for a client (32)/server (30) environment. The server (30) stores conference model data (60) such as a shared chalkboard or a molecular model and each client has a copy of the conference model data (61). When one of said clients (32A, 32B, 32C) edits the model (61) it creates an instruction (64A) for operating on the model and sends the instruction (64A) to the server (30). The server (30) operates (62) on its conference model data (60) on receipt of the instruction (64A) and resends the instruction (64B) to each of the clients (32A, 32B, 32C) and each client (32A, 32B, 32C) performs the same operation (63) on their respective copies of the conference data model (61). Whereby after a plurality of different operating instructions (64B) from different clients (32A, 32B, 32C) the respective copies of the conference model data (60) are equivalent.

Abstract: The present invention provides network management of a network or multiple networks, using a Web client, and including multimedia and hypermedia capability. The present invention provides a unified, remote, graphical, transparent interface for Web users, working at a Web client, to a variety of managed networks. The present invention receives requests from a Web client forwarded by a Web server and interacts with the managed networks and their associated objects to obtain information. The present invention then converts this information in real time to hypermedia document format in HTTP and HTML, and transmits this information to the Web client via the Web server, appearing to the client as if the information received were a Web file ab initio. This permits a Web user to manage multiple networks and access multiple networks via a single Web client, thus providing a unification of the management interface for dissimilar managed networks, and devices.

Abstract: In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established.

Abstract: A generic management framework for a network management system enables management services and management agents to be added in use as required. Management services can be loaded or plugged into the framework dynamically. As a result a management structure can be provided which is scalable and dynamic and can evolve as requirements change. Management information is modelled as management beans. Network management adaptors can also be added as required to the framework to support protocols such as HTTP, SSL, RMI, SNMP. Remote applications can thereby control the management beans remotely through different protocols.

Abstract: An address-translating connection device which makes it possible to dynamically assign an IP address to a private address when a connection is made to inside of a LAN from outside. When an inquiry made by designating a host name as to a global address of the same is received from the first network, a private address-retrieving device looks up a host-name/private-address correlation storage device to retrieve a private address correlated to the designated host name. When a determining device determines that the address-correlation storage/translation device does not store a global address correlated to the retrieved private address, a storage device extracts an available one of global addresses to correlate the available global address to the retrieved private address, and cause the address-correlation storage/translation device to store therein the addresses correlated to each other. At the same time, a first notifying device sends out into the first network a reply notifying the global address stored.

Abstract: A method and arrangement for transmitting multiple copies of a frame from a network switch in a packet switched network stores a single copy of the frame received at the switch into external memory. The frame is stored at a location in memory pointed to by a frame pointer. In queuing multiple transmissions of the stored frame in the switch, the frame pointer, and not the frame itself, is replicated and queued for transmission in the network switch.

An algorithm for balancing the traffic is used to select appropriate data processing devices as routers.

Abstract: A method is provided for graphically depicting detailed state and status information for network objects, particularly network objects forming part of a telecommunications network. A graphical representation of a network is displayed in which a basic icon is displayed for each network object. More commonly occurring state and status combinations are conveyed by imparting attributes to the basic icons such as dashed, solid, or three dimensional outlines. Less commonly occurring state and status combinations are conveyed by attaching modifier icons to the basic icons. The method is particularly suited to providing a detailed visual representation of the states and statuses included in the OSI standard.
