Abstract

Recent work on self-stabilizing routing in publish/subscribe systems showed that it is feasible to automate reconfigurations in case of faults by enabling the system to recover from arbitrary transient faults. In this paper, we discuss how to incorporate planned reconfigurations of the broker topology into self-stabilizing publish/subscribe systems without service interruption. We present an algorithm that uses a coloring mechanism to enable the system to be automatically switched from one system configuration to another. The colors thereby synchronize the broker overlay and the publish/subscribe routing layer.
