Filed: 1995-05-17
Abstract: A network management facility is adapted so that it obtains information including connectivity data as well as the identities of discrete network elements from an associated network and then uses the information to determine the configuration of the network. The management facility then generates, for storage in a network management database, data records characterizing the configuration of the network, as defined by the components, circuits, etc., forming the network. Once the database has been created in this manner, the network management system may thenuse the contents of the database to provision requests entered by network users, for example, a request for additional transmission bandwidth. The database may also be used to evaluate a network condition, such as a condition characterized by a trouble alarm. Further, the network management system automatically updates the contentsof the database to reflect a change in the associated network, thereby eliminating the need to rely on personnel to perform that task.
