LUNI Interface in Relation to LANE Clients and Services
LAN Emulation Client
(LEC)
The LAN Emulation Client (LEC) performs data forwarding and address
resolution, provides a MAC level emulated Ethernet service interface to
higher level software, and implements the LANE User to Network
Interface (LUNI) in order to communicate with other components within a
single ELAN.
Each LEC is incorporated in an ATM edge device, such as a SuperStack II
Switch 2700 or 7X00 Interface Card, and represents a set of the device’s
LAN users to the ATM network. A LEC has a unique
LEC ID
as well as an
ATM address
by which it is known in the ELAN. It handles the forwarding
of its LAN users’ data frames over the ATM network to their destination, a
task which also includes ascertaining the destination LEC address and
setting up the connection between them.
Also provided is a MAC-level emulated Ethernet service interface to
higher level software which implements the
LAN Emulation User to
Network Interface
(LUNI).
An ELAN is assigned a name (
ELAN name
). A LEC joining an ELAN may
use the ELAN name in the configuration or join phase.
