A Multi-Level Meta-Object Protocol for Fault-Tolerance in Complex Architectures

Proceedings of the 35th IEEE/IFIP International Conference on Dependable Systems and Networks (DSN'2005), DCCS Track, Yokohama, Japan, June, pp. 270-279, ISBN 0-7695-2282-3, IEEE Computer Society, 2005 (10p.)

The past decade has seen an increasing use of complex computer systems made of third party components to develop mission critical applications. To insure the dependability of those systems in a sound and maintainable manner, technologies are needed to add fault-tolerance mechanisms transparently, while maintaining efficiency, high coverage, and evolvability. In this paper, we present a generic framework that addresses this problem and can be used within current industrial software. Our proposal is based on a limited set of core concepts inspired from plant biology and meta-object protocols. It provides separation of concerns for the implementation of adaptive fault tolerance strategies, while maintaining a global inter-level perception of the system runtime behavior. We demonstrate its practicality by using it to control the non-determinism of a CORBA/UNIX system.
