Operation of the LAN Emulation
The following functions are performed by the LAN Emulation. The LAN Emulation
Clients (LEC) and the LAN Emulation Servers interact by way of a well-defined
interface (LUNI).
• Connecting a LEC to an ELAN
• Address Registration
• Address Resolution
• Data Transfer
Connecting a LEC to an ELAN
The connection function of the LEC with the LAN Emulation Server (LES) includes
the following:
• LECS connect phase in which a LEC establishes a configuration data-direct VCC
to the LECS (optional).
• The configuration phase in which the LEC discovers the LES.
• The join phase in which the LEC establishes its control connections to the LES.
The LEC may also implicitly register one MAC address with the LES.
• The registering by the LAN Emulation Client of any number of MAC addresses
and/or route descriptors.
• The establishment of a connection to the BUS by the LAN Emulation Client.
