  • Control of topology views in network management
    Patent number: 6687832
    Abstract: A system for controlling topology views for operators in network management includes a data-storage unit which stores data of a base topology view, a security-management unit which controls access-authorization information with respect to each of the operators, the access-authorization information for a given operator defining network elements accessible by the given operator, and a topology-view-management unit which generates data of a dependent topology view by making a partial copy of the data of the base topology view only with respect to the network elements accessible by the given operator, thereby providing the dependent topology view to be presented to the given operator.
