Abstract: A data conferencing network comprises multiple nodes linked together by a communications path 240. Each node has a copy of a shared data set, which is being updated by the users of the data conferencing network. Updates generated by a users 215 at any particular node are added to a first queue 220 at that node. A permit-token having an associated permit number circulates around all the nodes. When in possession 230 of the permit token, a node can broadcast an update from its first queue. In doing so, it associates the current permit number with the update (to give an update level), and then increments the permit number by one before forwarding the permit token to the next node in its circulation route. Updates received at a node are placed into a second queue 250. Each receiving node maintains a current update level, representing the most recent update number applied to the shared data set at that node. The second queue is searched for the update having an update level, which exceeds the current update level by one unit. This update is then taken from the queue and applied to the shared data set, and the current update level is accordingly incremented by one unit.

Abstract: Se facilita una entrada para enlazar entre diferentes modelos de comunicación. La entrada que se puede implementar en un programa de ordenador instalable en un sistema servidor facilita la interoperación entre programas de ordenador que requieren sesiones de comunicaciones síncronas y programas de ordenador basados en un modelo asíncrono de comunicación. La invención habilita a un cliente conectado síncronamente a visitar de nuevo las interacciones con un servidor y comunicar programas asíncronamente, para intercalar las interacciones con más de una aplicación, y asociar juntos los pares petición-respuesta de una aplicación de ejecución larga. En particular, la invención proporciona el aparato y los procedimientos que habilitan el enlace entre el servicio WWW de Internet y un sistema de mensajería de propósito general.

Abstract: Provided is a gateway for linking between different communication models. The gateway, which may be implemented in a computer program installable on a server system, facilitates interoperation between computer programs which require synchronous communications sessions and computer programs based on an asynchronous model of communication. The invention enables a synchronously-connected client to revisit interactions with a server and asynchronously communicating programs, to interleave interactions with more than one application, and to associate together request-response pairs of a long running application. In particular, the invention provides apparatus and methods enabling linking between the Internet WWW service and a general purpose messaging system.

Abstract: Provided is a gateway for linking between different communication models. The gateway, which may be implemented in a computer program 200 installable on a server system 230, facilitates interoperation between computer programs which require synchronous communications sessions and computer programs based on an asynchronous model of communication. The invention enables a synchronously-connected client to revisit interactions with a server and asynchronously communicating programs, to interleave interactions with more than one application, and to associate together request-response pairs of a long running application. In particular, the invention provides apparatus and methods enabling linking between the Internet WWW service and a general purpose messaging system. A preliminary reply is sent within the synchronous session before receipt of a reply via the asynchronous model. The preliminary reply includes a session identifier assigned by the server system.

Abstract: A method and apparatus for automatically changing the display in overlapping rectangular viewport areas of a display screen of a digital display apparatus and in which each viewport area is assigned a different priority level. The method includes the steps of a) storing in a random access store indications of the position and size of each viewport area, together with an indication of the priority level of the viewport area, b) constructing a first matrix of (2n+ 1) 2 elements, where n is equal to the number of viewport areas, by assigning a vertical component to each vertical coordinate of each viewport area and a horizontal component to each horizontal coordinate of each viewport area, and for each element so formed storing an indication of the highest priority level of the viewports falling within the boundary formed by the coordinates defining the element, c) receiving an indication that the display of a particular viewport is to be changed, d) constructing a second matrix for the viewport area, the display of which is to be changed, by storing, for each element, an indication whether or not a portion of the particular viewport, that is to be changed, falls within its boundary and associating the corresponding elements of identical rows and columns together, e) receiving indications of the coordinate values of the displays to be displayed in the viewport area, f) using the condensed matrix to determine the coordinates of the received display information that can be displayed in the viewport area, and g) storing the indications of the coordinate values in the random access store. The apparatus includes a communications processor and a procedure processor arranged to be controlled to perform the method.
