A model-based approach to adding autonomic capabilities to network fault management system

Adding autonomic capabilities to network management systems provides great promise in delivering high QoS while lowering operation and maintenance cost. In this paper, we present a model-based approach to adding autonomic capabilities to a fault management system for cellular networks. We propose the use of modeling techniques to specify software failures and their dispositions at the model level for the target system. This facilitates the deployment of a control loop for adding autonomic capabilities into the system architecture, which include self-monitoring, self-healing, and self-adjusting. Our case study on the Intelligent Network Fault Management system illustrates the proposed approach by adding and deploying these autonomic capabilities derived from self-* model specifications, to mitigate the risk of specified failures and maintain the level of healthiness of the system, dynamically and effectively.
