This article considers two hierarchical routing models based on the optimization of the size of topology databases and routing complexity, respectively. Some design guidelines are also suggested for an hierarchical PNNI structure of a network topology databases and routing complexity, respectively. Some design guidelines are also suggested for an hierarchical PNNI structure of a network topology. Copyright © 1999 John Wiley & Sons, Ltd.
