Abstract

Method for the transmission of information packets between a source LEC of a first ELAN and a destination LEC of a second ELAN, having the following method steps: determination of the destination ATM address by transmission of an address resolution request of the source LEC to the second ELAN via a CLS wideare network offering a connectionless service and resolution of the destination MAC address in the second ELAN into the appertaining ATM address; initiation of a connection setup between source LEC and destination LEC via an ATM network ranking higher than the first ELAN and the second ELAN upon employment of the identified destination ATM address; and transmission of the information packets via the higher-ranking ATM network. In one exemplary embodiment, the determined ATM address is transmitted to the first ELAN via the CLS wide-area network as address resolution response and is transmitted thereat to the source LEC, and the source LEC initiates a connection setup to the destination LEC.
