Abstract

As the deployment of interactive computer systems are rapidly incorporated into people s daily reality in the form of online services, such as electronic commerce, distance learning, telemedicine, among other emergent applications, in addition to performance and security, requirements of dependability regarding the responsiveness dynamics become essential to the effectiveness of their usefulness. Techniques for the analysis and synthesis of mechanisms the must operate under temporal restrictions belong to the technological domain of real-time systems, in which substantial contributions earned along its development have focused control and automation applications, characterized by deterministic environment and requirements. The present work aims at contributing to the recent investigations in the extension of these achievements for the field of interactive computer systems, characterized by non-deterministic environment and requirements. Having Web systems as the focus, the goal of this work research work is the study of real-time scheduling polices for QoS guarantee based on parameters of average and dispersion of response times.
