An Adaptive Dependable Fault-Tolerant Scheme for Distributed Systems


The growing importance of dependable applications and the need for a higher quality of service (QoS) in distributed systems justify the increasing interest in fault-tolerant distributed systems. In this paper, we present an adaptive management framework for providing dependability and security in distributed systems through failure management and security management. Our mechanism is different from other works because our research focuses on building a scalable, adaptive and dependable management mechanism which is a combination of QoS management, failure management, and security management. The QoS management to ensure that crucial resources within the system has adequate capacity, failure management to ensure the distributed systems have strong dependability, while security management to ensure the information within the system has secure guarantee. Our performance analysis shows that the mechanism adds an acceptable number of additional resources making the approach is feasible.
