LAN emulation A group of software components that allows asynchronous transfer mode (ATM) to work with legacy networks and applications. With LANE, you can run your traditional local area network (LAN)-aware applications and protocols on an ATM network without modification. LANE makes the ATM protocol layers appear to be an Ethernet or Token Ring LAN to overlying protocols and applications. LANE provides an intermediate step between fully exploiting ATM and not using ATM at all
