A CORBA-based performance management framework for multi-layer network environment

Abstract

Many researchers have addressed issues of performance management based on network elements, however, little attention has so far been given to issues of the scalable performance management framework uniformly applicable to heterogeneous network environment. To address this deficiency, this paper proposes a CORBA-based performance management framework for multi-layer network environments, such as ATM, Frame Relay (FR) and Internet. The framework includes a generic network model that can uniformly be applicable to such environments and performance metrics for each network. In addition, this paper describes the inter-relationship among heterogeneous networks in terms of performance management and network resource management scheme as a result of performance data collection and analysis. A system architecture is also proposed, including pro-active and re-active performance management, which is implemented through CORBA objects and provides IDL interfaces. It orchestrates network resource reconfiguration through the methods of performance measurement, policy management, and analysis.
