A bandwidth scheduler for triple play services based on fuzzy theory

The search for improvement in the process of diffusion of information has led to many advances in access technologies. In initiatives for digital/social inclusion, this improvement is of utter importance, particularly in scenarios where the infrastructure becomes a barrier in communication. An alternative to improve communication and thus providing quality of service is to adjust the use of resources/bandwidth required by the applications. This paper presents an application-scheduling algorithm, based on fuzzy logic, to optimize the use of bandwidth and guarantee QoS for existing applications. Simulations were made from a built testbed for xDSL technology; results showed that the proposed scheduler is able to optimize the channel, guaranteeing minimum levels of QoS based on the particular needs and characteristics of each application.
