Title
(EN) LOGICAL IP ADDRESS ASSIGNMENT IN ATM LAN
(FR) AFFECTATION D'UNE ADRESSE LOGIQUE IP DANS UN RESEAU LOCAL MTA
Abstract
(EN)
Disclosed is a method for configuring logical IP subnetworks which simultaneously supports autoconfiguration and mobile hosts (804). These capabilities are supported at the datalink layer, rather than at the network layer, as in protocols currently in use or under discussion in the Internet community and ATM Forum. The method may be used to reduce the consumption of network resources, improve delay times, and permit enhanced privacy for mobile hosts. The invention provides a method for connecting a host (502) to logical LAN, such as a logical Internet Protocol subnet when the host is attached to a datalink layer network (508) (such as an ATM network) for a LAN to which it is being physically connected, the host is assigned a network layer address (such as an IP address) identifying the desired logical LAN.

L'invention concerne un procédé qui permet de configurer des sous-réseaux logiques IP pouvant accepter simultanément une autoconfiguration et des ordinateurs centraux mobiles (804). Ces fonctions sont acceptées au niveau de la couche liaison de données plutôt qu'au niveau de la couche réseau, comme c'est le cas pour des protocoles communément utilisés ou soumis à discussion au sein de la communauté Internet et du Forum MTA. Le procédé peut être utilisé pour réduire la consommation de ressources réseau, raccorcir les délais d'attente et assurer une confidentialité renforcée pour les ordinateurs centraux mobiles. L'invention concerne un procédé qui permet de raccorder un ordinateur central (502) à un réseau local logique, tel qu'un sous-réseau logique 'Internet Protocol'. Pendant que l'ordinateur central est relié à une couche liaison de données (508) (tel qu'un réseau MTA) d'un réseau local auquel il est physiquement raccordé, on lui affecte une adresse de couche réseau (telle qu'une adresse IP) qui identifie le réseau local logique désiré.
