Distributed databases and other networked information systems use copies or mirrors to reduce latency and to increase availability. Copies need to be refreshed. In a loosely coupled system, the copy sites are typically responsible for synchronizing their own copies. This involves polling and can be quite expensive if not done in a disciplined way. This paper explores the topic of how to determine a refresh schedule given knowledge of the update frequencies and limited bandwidth. The emphasis… CONTINUE READING
