A Distributed Algorithm for Adaptive Replication of Data

Wolfson, Ouri

We present a distributed algorithm for replication of a data-item in a set of processors interconnected by a tree network. The algorithm is adaptive in the sense that the replication scheme of the item (i.e. the set of processors. each of which stores a replica of the data-item). changes as the read-write pattern of the processors in the network changes. The algorithm is optimal in the sense that when the replication scheme stabilizes, the total number of messages required for the reads and writes is minimal.
