A Sense and React Plane Structured Autonomic Model Suitable for Quality of Service (QoS) Management

Increased complexity of the computer networks arising from the diversity of devices, applications and technologies, combined with the growing demand from users, requires a computer network that offer adequate treatment to multiservice (voice, video, web applications), its quality of service (QoS) requirements. This complicates the human administration even with the adoption of policy-based management (PBM) systems, since the efficiency of the model is linked to the knowledge and skills of the administrator to define a policy database that meets all possible states. In this paper is presented a model with autonomic capabilities able manage quality of service in computer networks totally policy-based. We introduced a knowledge layer in a policy based management traditional so that the policies were created in autonomic way, replacing the human interaction in the definition of the policy database.
