Routing

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.
