PNNI Functions
PNNI is a function whereby switches in a network exchange information to
automatically prepare a dynamic routing table and route cells by referring to that
table. Such information is exchanged periodically or whenever there is a change.
The information is used by each switch to prepare a dynamic routing table
between PNNIs that reflects network status in a timely fashion.
Figure 5-4 illustrates the procedure by which the PNNI function prepares a
dynamic routing table.
