Title
(EN) ARRANGEMENT FOR SUPPLYING LOCAL NETWORK EMULATION SERVICE OVER PUBLIC CONNECTIONLESS ATM-NETWORK
(FR) DISPOSITIF DESTINE A FOURNIR UN SERVICE D'EMULATION DE RESEAU LOCAL PAR LE RESEAU ATM PUBLIC SANS CONNEXION
Abstract
(EN)
The present invention relates to an arrangement for supplying local network emulation services over a public connectionless ATM-network. The ATM-network is in charge of connectionless data communication traffic by means of a broadband data service network (BDS). Private local networks (LAN) can be connected to the ATM-network to exchange traffic with other local networks. According to the invention the ATM-network emulates local networks so that the ATM-network can deal with the local network traffic, i.e. both public and private data communication services over ATM. According to the invention the BDS-network comprises servers which function as address resolvers for local network addresses and as local network relays for routing of the local network traffic via the ATM-network. The server uses preferably unit specific addresses (MAC) and local emulation groups (LEG) as address in the BDS-service.

Dispositif destiné à fournir un service d'émulation de réseau local par l'intermédiaire d'un réseau ATM public sans connexion. Le réseau ATM se charge du trafic de communication des données sans connexion au moyen d'un réseau de services de données à large bande. Les réseaux locaux privés peuvent être connectés au réseau ATM pour échanger le trafic avec d'autres réseaux locaux. Selon l'invention, le réseau ATM émule les réseaux locaux de façon à pouvoir gérer le trafic de ceux-ci, autrement dit les services de communication de données privés et publics, sur ATM. Selon l'invention, le réseau de services de données à large bande comporte des serveurs qui jouent le rôle de séparateurs d'adresse pour les adresses des réseaux locaux et de relais des réseaux locaux pour l'acheminement du trafic des réseaux locaux sur le réseau ATM. Le serveur emploie de préférence des adresses spécifiques des unités (MAC) et des groupes d'émulation locale (GEL) comme adresses dans le service de données à large bande.
