Communication Adaptive Self-Stabilizing Group Communication

Report, 2000

This paper presents the first (randomized) algorithm for implementing self-stabilizing group communication services in an asynchronous system. Our algorithm converges rapidly to legal behavior and is communication adaptive, namely, the communication volume is high when the system recovers from the occurrence of faults and is low once a legal state is reached. Communication adaptability is achieved by a new technique that combines transient fault detectors.
