Distributed systems and fault tolerance

Developing a distributed application is hard due to the comp- lexity inherent to distributed communication. Moreover, distributed ob- ject communication technology is always changing, todays edge technol- ogy will become tomorrows legacy technology. This paper proposes an incremental approach to allow a divide and conquer strategy that copes with these problems. It presents a design pattern for distributed object communication. The proposed solution decouples distributed object com- munication from object specific functionalities. It further decouples log- ical communication from physical communication. The solution enforces an incremental development process and encapsulates the underlying dis- tribution mechanisms. The paper uses a stage-based design description which allow design description at a different level of abstraction than code.
