This unit looks at some of the architectural and programming paradigms used in distributed system development. You will learn about synchronous and asynchronous message passing, distributed objects technology and event-based bus architecture, before finally moving on to tuple architecture.
After studying this unit you should be able to:
- describe some of the architectural and programming paradigms used in distributed system development;
- describe message passing and the role of protocols within a message passing paradigm;
- introduce the concept of a distributed object;
- describe how event-based architectures are used within distributed system development;
- introduce one implementation of an event-based architecture;
- outline the concept of tuple-based development;
- introduce the main ideas behind remote procedure call;
- introduce one commercial example of a tuple-based technology.

In this unit I look at a number of different programming and design styles associated with distributed system development. The unit first examines message passing and the role of protocols – both fixed and adaptive protocols. Two styles of message passing are also examined: synchronous and asynchronous message passing. The next part of the unit introduces distributed object technology. Event-based development relies on listener objects listening to events which are propagated along a bus; the unit looks at this form of implementation and details its relationship to multicasting. A commercial implementation of event-based technology is presented. The unit also includes a description of the oldest paradigm: remote procedure call. The unit concludes with a description of the most abstract model we have available for distributed system development: that of tuple architectures. A Java implementation known as JavaSpaces concludes the unit.
