In this course I look at a number of different programming and design styles associated with distributed system development. The course 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 course introduces distributed object technology. Event-based development relies on listener objects listening to events which are propagated along a bus; the course looks at this form of implementation and details its relationship to multicasting. A commercial implementation of event-based technology is presented. The course also includes a description of the oldest paradigm: remote procedure call. The course 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 course.
