A Three-Dimensional Evaluation Model for Network Management System

The growing of network applications and the advances in network services demand for more complex and flexible network management systems. It becomes difficult to evaluate the performance of such a system using the traditional, simple and arbitrary evaluation methods especially when the system is designed for a specific purpose. Systematic evaluation models should be built to evaluate if a system meets the specified requirements while does not sacrifice much of the network performance. In this paper, we propose a three-dimensional evaluation model for network management system which takes cost, impact, as well as operation into consideration at the same time. We define evaluation index as a performance indicator, which is detailed elaboration for the proposed model. We believe that the three-dimensional evaluation for network evaluation can be better suited in nowadays network environment
