Adaptation des applications distribuées à la Qualité de Service fournie par le réseau de communication

Abstract : Various new networking applications have appeared in the past ten years. Packet switched networks initially designed for the transfer of text data are used nowadays by more complex traffics with strong constraints in terms of Quality of Service (QoS). Our approach considers that no strict guarantee can be obtained from communication system. In this context, we propose a new QoS Architecture called "QdS-Adapt". It offers a general framework that permits applications to adapt dynamically their execution to resources fluctuations. The architecture includes a network metrology service. It has been designed to allow the implementation of various measurement techniques. The feasibility of the architecture has been verified on two tele-operation applications of a mobile robot. Experimentations show that the architecture allows on-line adaptation strategies to be implemented and that the impact of QoS degradations on the application functioning can be limited.
