Dependable Distributed Systems - A Research Project Overview

Complex distributed systems require dependability encapsulated in coherent system parts. We achieve fault-tolerance through replication and optimize dependability by trading availability against constraint consistency in the case of site failure or network partition. A real-life telecommunication application proves the concept by using synchronous and asynchronous replication techniques.
