Configuring LAN emulation on the LAN emulation client Server and destination LAN emulation How to retrieve the ATM address of the client

摘要

A LAN emulation client capable of obtaining an ATM address of a LAN emulation configuration server or another LAN emulation according to need in a LAN emulation user / network interface at the time of a LAN emulation user / network interface, a LAN emulation configuration server and an ATM The present invention relates to an address retrieval method and a data retrieval method for retrieving a MAC address from a user terminal by continuously searching a database provided in a LAN emulation client for a total number N of stored information, Detect a corresponding MAC address that can be corresponded; If a corresponding MAC address is detected, fetch the corresponding ATM address for connection with the destination LAN emulation client and proceed to the route for processing of the next processing; If the corresponding MAC address is not detected, the LAN emulation client sends a request signal to the LAN emulation configuration server; In response to the request signal, continuously searches the database provided in the LAN emulation configuration server by the stored total number M of data to detect a corresponding MAC address corresponding to the received MAC address; When the corresponding MAC address is detected, the corresponding ATM address is fetched for connection with the destination LAN emulation client, the fetched ATM address is transmitted to the LAN emulation client, and then the processing proceeds to the route for processing of the next processing; If the corresponding MAC address is not detected, the LAN emulation client sends a message to the user terminal informing the database in the LAN emulation configuration server that there is no corresponding MAC address corresponding to the received MAC address, and then sends the message to the root for the processing of the next processing It is possible to find the ATM address of the destination LAN emulation to be connected in the database provided in the corresponding LAN emulation or obtain the ATM address of the LAN emulation configuration server contained in the database provided in the LAN emulation configuration server .
