CA 2179349

A method and apparatus for providing a three-way connection between a mobile computing device, a stationary computing device and a computer network. When there is an established connection between a mobile computing device (e.g. a notebook computer) and the stationary computing device (e.g. desktop PC) over the wireless communication channel (e.g. infrared link), the system operates in BRIDGE mode. In BRIDGE mode the system redirects information packets in the OSI layer 2 (data link layer). When a notebook computer is not attached, the system operates in PASSTHROUGH mode and all non-broadcast message traffic from the Ethernet LAN is filtered by the Ethernet adapter based on the network address or group address of the desktop PC.

Méthode et appareil permettant une connexion trois voies entre un dispositif informatique mobile, un dispositif informatique stationnaire et un réseau informatique. Lorsqu'une connexion existe entre un dispositif informatique mobile (p. ex. un bloc-notes électronique) et le dispositif informatique stationnaire (p. ex. micro-ordinateur de bureau) sur le canal de communication sans fil (p. ex. liaison infrarouge), le système fonctionne en mode BRIDGE (passerelle). En mode BRIDGE, le système réachemine les paquets d'information dans la couche OSI 2 (couche liaison de données). Lorsqu'un bloc-notes électronique n'y est pas raccordé, le système fonctionne en mode PASSTHROUGH (direct) et tout le trafic de messages non diffusés provenant du réseau local Ethernet est filtré par l'adaptateur Ethernet selon l'adresse de réseau ou l'adresse de groupe du micro-ordinateur de bureau.
