This memo defines how ILMI-based Server Discovery, which provides a
method for ATM-attached hosts and routers to dynamically determine
the ATM addresses of servers, shall be used to locate MARS servers.
Presently, configuring a host or router to use MARS  is cumbersome
and error-prone since it requires at least one ATM address to be
statically configured on each host or router in the network.
Further, it is impossible to implement a diskless host to use MARS
since local configuration is required. ILMI-based Server Discovery,
hereafter referred to as "server discovery," provides a solution to
A brief overview of the Integrated Local Management Interface (ILMI)
and the Service Registry MIB, as defined by the ATM Forum, are
provided in this memo. The reader should consult  for a complete
description of ILMI and this MIB, but the information contained here
is sufficient for an understanding of its use to support MARS server
2. Integrated Local Management Interface
The Integrated Local Management Interface (ILMI)  provides a
mechanism for ATM-attached devices, such as hosts, routers, and ATM
switches, to transfer management information. It is based on the
Simple Network Management Protocol (SNMP), Version 1, and supports
get, get-next, set and trap operations.
The ILMI specification designates the switch side of the ATM link as
the 'network side' and the host/router side of the ATM link as the '
user side.' The Service Registry MIB, which is outlined in Section 3,
is implmented on the network side and is queried from the user side.
3. ILMI 4.0 Service Registry MIB
Server discovery utilizes the Service Registry MIB defined by the ATM
Forum in ILMI Specification Version 4.0 . To support the existing
framework for IP over ATM, as embodied by ATMARP and MARS, ATM
switches must support the Service...
