Managing the Network State Evolution over Time Using CORBA Environment

Abstract—This paper proposes a CORBA-based framework for managing the network state evolution over time. This framework is based on the concept of CORBA temporal agents, capable of man-aging the past and current behavior of network resources. Man-aged objects use specific time attributes for representing how their values are evolving in time. Moreover, specially designed opera-tions (services) enable users to exploit the temporal dimension of management information in order to understand the past, control the present, and thus even predict the future of managed objects. The management environment is designed in order to provide coex-istence and interoperability with existing management platforms. Index Terms—Communication system operations and manage-ment, computer network management, object-oriented methods, temporal databases. I
