ATM LANE Components
Description
LANE Client (LEC)
There is a LEC for each member of the ELAN. LECs implement
LE-ARP address resolution and emulate a LAN for higher-level
protocols. LEC builds a table to map MAC addresses to ATM
addresses. Each LEC has an ATM address. LECs can be a computer
station, switch, or router.
LANE Server (LES)
The LES is the central resource for the ELAN. It provides
management of all stations in the ELAN by providing address
registration and resolution and handling LE-ARP requests.
LANE Configuration Server
(LECS)
A LEC consults the LECS when first joining the ELAN. The LECS
provides the ATM address of the LES to the LEC.
Broadcast and Unknown
Server (BUS)
The BUS handles all broadcast, multicast packets, and unicasts sent
to unknown destinations. Because broadcasts do not exist in ATM,
the BUS processes the broadcasts to create virtual circuits to all
stations in the ELAN. The LES and BUS functions are commonly
implemented in the same device.
