METHOD FOR SEARCHING ATM ADDRESS OF DESTINATION LAN EMULATION CLIENT BY USING LAN-ARP CACHE IN LAN EMULATION CLIENT

摘要

The present invention relates to a method for enabling a LAN emulation client (LEC) to obtain an ATM address of a destination LAN emulation client by using a LAN emulation LAN_ARP cache at a LAN emulation user / network interface. To this end, the present invention, the first step of transmitting a LE_ARP Request signal from the LAN emulation client to the LAN emulation server; In response to the LE_ARP Request signal, transmitting a request signal to the plurality of destination LAN emulation clients and then maintaining a standby state for receiving a response signal thereto; A third step of storing an ATM address corresponding to a received ATM address transmitted through a link from a corresponding destination LAN emulation client to communicate when a response signal is input; A fourth step of checking whether the LE_NARP Request signal is input from the user terminal while the corresponding ATM address of the corresponding destination LAN emulation client to be communicated is stored in the LE_ARP cache; A fifth step of checking whether or not the storage time of the corresponding ATM address for the destination LAN emulation client to be communicated stored in the LE_ARP cache exceeds the predetermined holding time during the checking of the fourth step; And if it is determined that the LE_NARP Request signal is input in the fourth process or the check time in the fifth process determines that the storage time of the corresponding ATM address exceeds the predetermined holding time, the destination LAN emulation to be communicated stored in the LE_ARP cache. By deleting the corresponding ATM address of the client and then proceeding to the route for processing of the next processing, it is possible to quickly obtain the ATM address of the destination LAN emulation client to communicate with.
