Control of topology views in network management

A system for controlling topology views for operators in network management, comprising:

• a data-storage unit which stores shared data of topology views;
• a security-management unit which controls access-authorization information with respect to each of the operators, said access-authorization information for a given operator defining whether the given operator has a right to create, a right to delete, a right to modify, and a right to refer to one of the topology views;
• and
• a topology-view-management unit which controls access by the given operator to the one of the topology views based on the access-authorization information for the given operator.

A method of controlling topology views for operators in network management, comprising the steps of:

• storing data of a base topology view;
• defining access-authorization information with respect to each of the operators, said access-authorization information for a given operator indicating network elements accessible by the given operator;
• and
• generating 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.
