Process for determining a target ATM address
First Claim
1. A method for determining a destination ATM address as reply to an address resolution inquiry output by a source LAN emulation client of a first ELAN when a destination MAC address to be resolved is allocated to at least one LAN emulation client of a second ELAN, the first ELAN and the second ELAN being connected to a higher-ranking network, comprising the steps of:
- encapsulating a address resolution request in the first ELAN as ELAN frame in a frame format of the CLS wide-area network with an E-164 address allocated to the destination MAC address in the frame header part;
handing over the encapsulated address resolution request to the CLS wide-area network and transmitting the encapsulated address resolution request to the second ELAN;
de-encapsulating the encapsulated address resolution request and handover to an LAN emulation server responsible for the address type of the second ELAN in the ELAN frame format;
resolving the destination MAC address into an appertaining ATM address by the LAN emulation server of the second ELAN and outputting an address resolution response;
encapsulating the address resolution response into the frame format of the CLS wide-area network and transmitting the encapsulated address resolution response to the first ELAN;
de-encapsulating the encapsulated address resolution response and handing over the de-encapsulated address resolution response to the source LAN emulation client.

Abstract
Method for the determination of a destination ATM address as reply to an address resolution inquiry output by a source LAN emulation client of a first ELAN when the destination MAC address to be resolved is allocated to at least one LAN emulation client of a second ELAN and the first as well as the second ELAN are connected to a higher-ranking network, having the following method steps: encapsulation of the address resolution request present in the first ELAN as ELAN frame in a frame format of the CLS wide-area network and transmission via the CLS wide-area network to the second ELAN; de-encapsulation of the encapsulated address resolution request and handover to an LAN emulation server LES of the second ELAN in the ELAN frame format; resolution of the destination MAC address into an appertaining ATM address by this LAN emulation server of the second ELAN and output of an address resolution response; encapsulation of this address resolution response into the frame format of the CLS wide-area network and transmission to the first ELAN; de-encapsulation of the encapsulated address resolution response and handover to the source LAN emulation client.
