ILMI Functions

The signaling for establishing SVC connections is transferred by referring to the routing table maintained by each switch in the network.

There are two types of routing table: static routing table and dynamic routing table. the ATM Switch provides the ILMI (Integrated Local Management Interface) and PNNI (Private Network-Network Interface) functions for preparing and revising the dynamic routing tables. Static routing tables can also be revised manually.

ILMI is a function for learning the configuration data of neighboring equipment when an end system is connected to a switch or when a switch is connected to another switch.

The ILMI function includes a switch-terminal address registration function. This function is triggered by a trap. The switch adds the inherent address of each terminal to its network prefix and registers the result as the ATM address of each terminal.

A switch prepares dynamic routing tables by this address registration function. Figure 5-3illustrates the procedure of ILMI address registration.
