A load-balancing distributed platform based on differentiated services for a telecare application

Abstract : Telecare applications are composed by different kinds of services. Some of these services require high level availability and performance because they involve human lives. One possible solution to improve availability and performance in these applications is to make an efficient distribution of service avoiding concentration of several tasks on only one server. This work presents a load-balancing platform based on differentiation of services that increases application-level QoS (quality of service) in a telecare application. The platform allows the coexistence of Internet services and distributed objects. We also present experimental results showing that the platform balances the imposed load and differentiates the QoS offered to different services.
