Abstract:
A method for transmitting information packets between a source local area network emulation client (LED) of a first emulated local area network (ELAN) and at least one destination LED of at least a second ELAN, comprising the following method steps:determining a destination asynchronous transfer mode (ATM) address of said destination LED by transmitting an address resolution request directly from a first LAN Emulator Server (LES) of said first ELAN over a connectionless service/services (CLS) wide-area network offering, a connectionless service to a second LAN Emulator Server (LES) located on said second ELAN without using any intermediate address server and by resolving the destination media access control (MAC) address of said destination LED of the second ELAN into the ATM address of said destination LED;initiating a connection setup between the source LED and the destination LED via an ATM network ranking higher than the first ELAN and the second ELAN using the destination ATM address provided directly by said second LES;transmitting information packets via the higher-ranking ATM netwvork.
