【 摘 要 】

Distributed software systems are the basis for many innovative applications (e.g. pervasive computing, telecommunication services, and control engineering). Many business cases focusing on specialized knowhow in the global market of software components, services, and infrastructures built upon these systems can be identified. The key for achieving scalable and main tainable distributed systems is dependability, because otherwise the complexity of distribution would leave the system uncontrollable. Hence, our approach aims at a concept for optimizing dependability. Similar to other approaches we use replication as means to pro vide transparent faulttolerance and persistence, but we especially focus on increasing availability by relaxing data integrity by using a mixture of asynchronous and synchronous replication techniques. This tradeoff al lows for a configurable and applicationspecific opti mum of availability, possibly even controlled during
