A multi-layered approach towards achieving survivability in autonomic network

Traditional network management technique that was largely controlled by humans is nowadays less and less feasible due to the increase complexities of current communication environment. This evolutionary change has led towards the requirement of autonomic network management. In this paper we propose a multi-layered autonomic network management architecture that incorporates various operators into a hierarchical structure. In particular we apply our architecture towards network survivability using a hierarchical Policy Based Management System. The paper also presents a review of current mechanisms used for network survivability.
