Components in LANE Services

This chapter gives a basic overview on the components of LANE Services.

LAN Emulation

The principles of LAN Emulation

LAN Emulation (LANE) enables legacy LAN applications to use an ATM transport medium transparently. Therefore, end-stations on existing Token Ring and Ethernet LANs can communicate with ATM end-stations.

Components of LAN Emulation

•LAN Emulation Client (LEC)

Every device on an ELAN has one or more LECs. This interfaces with the ATM network and performs most of the work of LAN emulation.

•LAN Emulation Server (LES)

There is at least one active LES (which may be a part of a distributed LES) allocated to each Emulated LAN (ELAN). The LES maintains a list containing both the LAN address (MAC address) and/or the route descriptor, and the ATM address for every LEC that is active on the ELAN.

•Broadcast Unknown Server (BUS)

There is only one active BUS (which may be a part of a distributed BUS) on an ELAN. The BUS is normally part of the same software module as the LES and provides the ELAN with broadcast and multicast facilities. It has direct connections to every LEC on the ELAN.

•LAN Emulation Configuration Server (LECS)

There is only one active LECS (however, you may have a number of standby LECS) on the network. The LECS maintains a list of all LESes. The LECS provides each LEC that contacts it with the ATM address of the LES hosting the ELAN that it should join. The LECS is usually located locally or remotely at the following ATM Forum Well-Known Address (WKA) 47.00.79.00.00.00.00.00.00.00.00.00.00.00.a0.3e.00.00.01.
