Chapter 21. ATM LAN Emulation
A set of systems connected to an ATM switch behaves like a bunch of telephones connected to a telephone switch: One instrument talks to another by making a call. This is very different from the way a LAN switch works. A station on a LAN fires off an individual frame to another system—or to all systems—any time it wishes. It does not have to go through a call setup first.
In spite of this vast difference in architectures, the ATM Forum was determined to integrate ATM switches into conventional LANs. The solution is called LAN Emulation (LANE).
LANE satisfies these ATM Forum objectives:
It enables a set of systems that have ATM NICs and are connected to ATM switches to emulate a conventional LAN.
It enables Ethernet ...
