  • the invention relates to apparatus and method suitable for use in network computing. More particularly, but not exclusively, it relates to aspects of server-centric computing.

These may include Unix, Windows from Microsoft, Inc., Redmond, WA and the Macintosh OS from Apple, Inc. of Cupertino, CA, but might also include Personal Digital Assistants (PDAs), and indeed any device with some form of communications link.

  • client devices Since the client device does not process applications locally, but merely displays to the user applications that are being managed by the server, display protocols make very few demands of the client. In this way, client devices can run on the widest range of hardware and the task of implementing a client device is made as simple as possible. Such client devices may therefore be stateless (no local storage) and may not be required to know how to interpret and display objects much more complex than menus and plain text. Such client devices are often referred to as "thin clients.”

Abstract

La présente invention concerne un serveur que l'on peut faire fonctionner pour fournir des ressources à un dispositif client. Le serveur comprend un moyen de négociation client pour établir une liaison de communication entre le serveur et un dispositif client, un moyen de réception de signal d'action d'entrée utilisateur destiné à recevoir un signal de détection d'action d'entrée utilisateur sur le dispositif client, et un moyen de gestion de session d'utilisateur que l'on peut faire fonctionner pour établir et utiliser une session d'utilisateur en réponse à la réception d'un signal d'action d'entrée indiquant une demande d'utilisateur pour celui-ci. On peut en outre faire fonctionner le moyen de gestion de session d'utilisateur pour demander des installations d'applications comme nécessaire et il comprend un moyen de rendu d'affichage utilisable pour restituer des données définissant une sortie d'affichage à afficher sur un dispositif client coopérant, et un moyen de transmission des données d'affichage destiné à la transmission, vers le dispositif client, sur la liaison de communication, de données d'affichage destinées à la représentation sur le dispositif client en tant que sortie utilisateur. L'invention concerne également un moyen d'hébergement que l'on peut faire fonctionner pour héberger une instance d'une application ou un proxy de celle-ci, et que l'on peut ainsi faire fonctionner pour fournir une installation d'application au moyen de gestion de la session d'utilisateur en réponse à une demande de celle-ci.
