Towards these of Models for Autonomic Network Management

This paper presents a model-based framework to support the autodifferent levels of cooperation (applicative/middleware/transport).

Van Wambeke, N., Armando, F., Chassot, C., Guennoun, K., Drira, K. and Exposito, E., 2008, in IFIP International Federation for Aiming to answering this problem, we propose a model-based framework for adaptability management. Our framework has been elaborated in the context of network management systems with service provisioning at the transport and network layers of the TCP/IP stack as the final objectives. Our approach provides, refines and exploits different models, each one representing a different point of view on the context. The models that represent other aspects of communication are automatically generated from higher level models representing the cooperation requirements and the communication constraints. Our research efforts have been developed to cover communication at the transport layer as well as the network layer. Our paper is organized as follows. Section 2 describes related work. Section 3 describes the different models of the framework. Section 4 presents an architecture to support the use of these models for automated network adaptation management as well as an example of their use in response to a change of collaboration. This architecture is currently under study and development within the European NETQoS Project. Section 5 provides conclusions and future works.
