An Adaptive Control Mechanism for Management of Networked Information Consistency

Abstract

This paper discusses techniques for managing in formation consistency and controlling the dy namic shared state for a large-scale virtual envi ronment. Depending on the system load, this ap proach can automatically switch the dynamic shared state from one level to another to prevent performance degradation. Simulations were used to evaluate the proposed adaptive control mecha nism, the three-level consistency approach, and the shared repository technique. Performance results show that both the proposed mechanism and the three-level consistency approach can maintain low system load over a wide range of participants, but the adaptive control mechanism can adapt to the state of server load and provide a better service quality.
