Operation of the LAN Emulation 381
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
Connection Management
Connecting a LEC to
an ELAN
The connection function of the LEC with the LAN Emulation Server
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 LAN Emulation Client discovers
the LAN Emulation Service.
The Join phase in which the LAN Emulation Client establishes its
control connections to the LAN Emulation Server. 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.
The LECS Connect and Configuration phases may be bypassed for certain
applications. The seperate Registration phase may be bypassed if the LEC
performs required address registration during the Join phase.
