An Active Temporal Model for Network Management Databases
Masum Z. Hasan · 1995
The purpose of a network management system is to provide smooth functioning of a large heterogeneous network through monitoring and controlling of network behavior. ISO/OSI has defined six management functionalities that aid in overall management of a network: configuration, fault, performance, security, directory and accounting management. These management functionalities provide tools for overall graceful functioning of the network on both day-to-day and long-term basis. All of the functionalities entail dealing with huge volumes of data. So network management in a sense is management of data, like a DBMS is used to manage data. This is precisely our purpose in this paper to show that by viewing the network as a conceptual global database the six management functionalities can be performed in a declarative fashion through specification of management functionalities as data manipulation statements. But to be able to do so we need a model that incorporates the unique properties of network management related data and functions. We propose a model of a database that combines and extends the features of active and temporal databases as a model for a network management database. This model of a network management database allows us to specify network management functions as Event-Condition-Action rules. The event in the rule is specified using our proposed event specification language . These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
