How to find the ATM (ATM) address of the LAN emulation server on the LAN emulation configuration server

摘要

The present invention relates to a method of searching an ATM address of a LAN emulation server in a LAN emulation configuration server in which an LEC can obtain an ATM address of an LEC in a LEC as needed in a LAN emulation user / network interface. The invention receives a request signal for a search to be sent to a LAN emulation server over a link when there is no ATM address in the database in the LAN emulation configuration server; In response to the received request signal, continuously searches the database provided in the LAN emulation server by the stored total number of information M to detect a corresponding MAC address corresponding to the received MAC address; If a corresponding MAC address is detected, fetch the corresponding ATM address for connection with the destination LAN emulation client, transfer it to the LAN emulation configuration server, and proceed to the route for processing of the next processing; If the corresponding MAC address is not detected, the LAN emulation server sends a message to the LAN emulation configuration server informing its database that there is no corresponding MAC address corresponding to the received MAC address, and proceeds to the route for the processing of the next processing Thus, the LAN emulation configuration server can reliably obtain the ATM address of the destination LAN emulation client to be connected in the database provided in the corresponding LAN emulation server.
