Chapter 10. ATM LAN Emulation (LANE)

LAN emulation (LANE) is one method used to extend broadcast domains across an ATM wide-area network (WAN), regardless of the upper-layer protocols in use. LANE extends VLANs (virtual LANs) through the ATM WAN cloud in what is known as an Emulated LAN (ELAN).

ATM LANs do not operate in the traditional way that other LAN implementations do, where a LAN host sends data frames at any time to one or multiple hosts on the LAN. Hosts on an ATM LAN must initiate a call setup process prior to data transmission.

With this major difference among LAN architectures, the ATM Forum wanted to integrate ATM switches into the conventional LAN architecture. This solution is known as LAN emulation, or LANE.
