LAN Emulation
LAN emulation refers to the technology of using the existing infrastructure of a
LAN and connecting the LAN to an ATM network on a bridge level to emulate the
connection. The specification of LAN emulation has been standardized by the ATM
Forum in its “LAN Emulation Over ATM Specification Version 1.0.”
LAN emulation allows existing LAN terminals to reciprocally communicate with
ATM terminals and make it possible to construct a virtual LAN that is free of
physical restraints.
Figure 2-6 and Figure 2-7 show the LAN emulation protocol stack between an ATM
terminal and an existing LAN terminal and its frame format when IP protocol is
used as the network layer.
