General Definition
of LAN Emulation
of LAN Emulation
LAN Emulation (LANE) provides an interface between traditional LANs
and ATM networks. LAN emulation is defined by ATM specifications
LANE 1.0.
and ATM networks. LAN emulation is defined by ATM specifications
LANE 1.0.
An ATM emulated LAN conforms to IEEE 802.3 for Ethernet LANs.
The use of LAN emulation bridge allows you to use a high-speed ATM
backbone to connect existing (legacy) Ethernet LANs. Figure 2-1
illustrates the basic function of LAN emulation.
