A multi-variables algorithm for dynamic reconfiguration of real-time distributed systems

Abstract

In this article, we address the problem of dynamic reconfiguration of systems. This problem is related to the operability of real-time systems with high availability, suffering multiple and recurrent deterioration of their performance. We propose in this paper a dynamic and multi-variable algorithm for the reconfiguration of such systems. This algorithm ensures the necessary reconfigurations to optimize the configurations of a system, whenever performance degradation occurs, in order to restore it to its optimal operating conditions. To achieve this goal, the algorithm dynamically determines the new viable configurations corresponding to the current degraded configurations. Then it ensures the transitions between these configurations, while reducing the consumption of temporary resources and generated overhead. The results of our experimenting show that the proposed algorithm yields significant results against the reference works, found in the specialized literature, dealing with the solving of such problems.
