Abstract

This paper presents an exercise in fault-containment on a weakly-stabilizing system. The exercise uses the weakly stabilizing leader election algorithm in [3], and shows how the effect of single faults can be contained both in space and in time. Our algorithm confines the effect of any single fault to the constant-distance neighborhood of the faulty process, and the contamination number is restricted to 4 with high probability for an array of processes. We also show that the expected recovery time from a single fault is independent of the array size, i.e., the solution is fault-containing in time too.
