LAN Emulation Components in Your Network
Each Emulated LAN consists of a single
LANE Service
,
and a number of LAN Emulation clients.
A LANE Service consists of:
■
A
LAN Emulation Server (LES)
■
A
Broadcast and Unknown Server (BUS)
■
Optional
LAN Emulation Configuration Server (LECS)
.
Figure 2-2 shows a logical view of a typical ELAN.
Figure 2-2
LAN Emulation Components
The router shown in Figure 2-2 is not a LAN
Emulation component, but would be required should
a device on one Emulated LAN need to communicate
with a device on another Emulated LAN.
You may wish to have more than one LECS on your
network for security reasons. For example, you may
wish the Finance department to be controlled by one
LECS and the rest of your network to be controlled by
a different LECS.
LAN Emulation and IBM Devices
LAN Emulation components are implemented in ATM
devices. The LAN Emulation standards (referenced in
the Bibliography) do not specify how each vendor
implements each of these components.
