Abstract

The purpose of this chapter is to position the Delta-4 architecture with respect to commercially recognised and available techniques. The comparison is made with respect to the Delta-4 application domains, characterized as large-scale, distributed information processing systems, and summarised in 1. It would not be appropriate here to make comparisons or draw conclusions about the respective merits of these architectures in other domains, e.g., transaction processing. Rather, the objective is to compare Delta-4 with alternative approaches to the design of distributed systems that are also required to be dependable, or exhibit real-time characteristics, or both. Before making this comparison, a summary of currently used commercial fault-tolerance techniques is included for reference. No similar analysis of real-time systems is offered since conventional stand-alone real-time operating systems are well-known and there are no known actual examples or de facto standards for distributed real-time systems.
