Dynamic design of a reliable computer network on using information theory

There exists a graph theoretic model of self-diagnosable system by Preparata et al. [1]. Using a corresponding information theoretic model, a reliability measure of a computer network was obtained [2]. Based on the a priori probability of failure of different computers and edge weights assigned for some test outcomes, probabilistically t-reliable system is characterised. Next optimal design of p − t reliable system is given. The associated design issues linked with dynamic environment are also highlighted.
