Preventing Rather Repairing - A New Approach in ATM Network Management

The introduction of new network services, broadband multi-media and advanced mobile communications imposes high requirements on ATM network management. In such an environment, an essential task of ATM management is to prevent faults and to support e cient resource allocation. The idea is to specify parameters, according to which the behaviour of the network is monitored, and to perform the necessary actions with respect to history-based tra c information before a degradation of quality of service is recognized by users. By describing a model, including parameters, actions, policies, and control mechanisms, we present a step towards self-regulating network management.
