Virtual tree: A robust overlay network for ensuring interval valid queries in dynamic distributed systems

摘要

Today's large scale distributed systems are characterized by strong dynamics caused by the inherent unreliability of their constituting elements (e.g. process and link failures, processes joining or leaving the system). This continuous dynamism has a strong negative impact on distributed algorithms designed to work on such systems. Regular registers [1], Replication [2], in-network aggregation[3], are all examples of such problem. © 2012 Springer-Verlag.
