The network management benefits of emulated LANs (ELANs) come from
increased flexibility in handling moves, adds, and changes. Membership in an ELAN
is not based on physical location; instead, logically-related stations are grouped to
form an ELAN (stations can also be members of multiple ELANs).
As long as ELAN memberships are retained, no reconfiguration is needed when
stations move to new physical locations. Similarly, no wiring modifications are
needed to move stations from one ELAN to another.
LAN Emulation Components
The following components implement an ELAN:
LAN emulation (LE) clients (LECs)
LAN emulation components that represent users of the Emulated LAN.
LE configuration server (LECS)
A LAN emulation service component that centralizes and disseminates
configuration data.
LE server (LES)
A LAN emulation service component that resolves LAN destinations toATM
addresses.
