Abstract. This paper introduces dual-quorum replication, a novel data
replication algorithm designed to support Internet edge services. Dual-
quorum replication combines volume leases and quorum based techniques
in order to achieve excellent availability, response time, and consistency
the references to each object (a) tend not to exhibit high concurrency
across multiple nodes and (b) tend to exhibit bursts of read-dominated
or write-dominated behavior. Through both analytical and experimen-
tal evaluation of a prototype, we show that the dual-quorum protocol
