摘要

PCT No. PCT/DE96/01170 Sec. 371 Date Dec. 22, 1997 Sec. 102(e) Date Dec. 22, 1997 PCT Filed Jul. 1, 1996 PCT Pub. No. WO97/02684 PCT Pub. Date Jan. 23, 1997Method 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.
