Abstract

Fault-tolerant communication systems use distributed clock synchronization algorithms for generating independent and stable clock sources. When these communication system must be aligned to an external clock, this requires a coordinated effort through all the participating nodes. The presented method proposes an efficient and flexible way for aligning a communication cluster with another one (or multiple ones) or external real time clocks using only minimal bandwidth and hardware resources. Nodes having access to the external clock or the other communication cluster distribute the information necessary for a collective shift throughout the communication cluster.
