Abstract
A three-level distributed database concept is proposed to meet the high performance requirements of an integrated communications network control system. The three levels are source, user, and control. By using fully replicated subject databases in the source level, one regional operations center can serve as a backup for any other center. The applications database in each user level is a subset of the subject databases residing in the source level. Hence, the user level is localized and can respond to near real-time network control requirements. The control level coordinates updates to the distributed database copies. Interactions among the three levels are discussed and four operational stages are considered: initialization, continuous update, global synchronization, and data recovery. A broader usage of the data dictionary is proposed. Simplification of the replicated database design in terms of isolation of global and local data and some implementation considerations are provided.
