Distributed data replication
and synchronization
Sponsor: NSF
Abstract
Many distributed applications in the current Internet are
massively replicated to ensure unsurpassed data robustness and scalability;
however, constant data churn (i.e., update of the source) and delayed
synchronization lead to staleness and thus lower performance in these systems.
The goal of this project is to pioneer a stochastic theory of data replication
that can tackle non-trivial dependency issues in synchronization of general
non-Poisson point processes, design more accurate sampling and prediction
algorithms for measuring data churn, solve novel multi-source and multi-replica
staleness-optimization problems, establish new fundamental understanding of
cooperative and multi-hop replication, and model non-stationary update processes
of real sources.
