ABSTRACT:
A system for maintaining network information. The system resides in a network comprising a plurality of sub-networks in communication with one another over a communications backbone. Each sub-network has a router for use in performing communications with other sub-networks. A directory service is linked to the communications backbone and includes a database. The database stores router attribute information that is published by each of the routers. Using a query engine associated with the directory service, meaningful information can be gathered from the database as a function of specified router attribute information.
