  Abstract

This paper proposes a mechanism for managing overload introduced by excessive web requests in real-time web service system. The many previous mechanisms statically manage the overload and thus the dynamic characteristics are not reflected. This paper proposes a mechanism that models system load based on control theory approach and includes its dynamic characteristics. We design a controller that is able to meet performance requirement. A feedback control system is implemented applying the proposed mechanism and the stable operation of system is verified through various simulation environments.
