Abstract
An ATM LAN emulation network is disclosed, in which a terminal can easily access an ELAN, to which he terminal was previously connected, via another ELAN. In this system, an LECS is mounted at each router, and the ATM address of the LECS is stored in advance in the ATM switch. When a terminal is connected to the ATM switch, the terminal is connected to an LECS using a Well-known address. When the LECS communicating with the terminal connected to the first ELAN receives a request for obtaining the ATM address of the second ELAN to which the terminal was previously connected, the LECS obtains the ATM address of the LECS of another ELAN of the next hop according to the IP routing information. If the next-hop LECS is connected to the second ELAN, the terminal can obtain the ATM address of the LES which manages the second ELAN via the LECS communicating with the terminal.
