Distributed Computer-Controlled Systems: The Dear-Cots Approach

The DEAR-COTS Replication Framework

The DEAR-COTS (Distributed Embedded ARchitecture using Commercial Off-The-Shelf components) architecture provides a COTS-based framework to execute reliable hard real-time applications. To ease the task of building reliable realtime applications on top of COTS components, a simple and transparent programming model is provided, in order that programmers abstract from the low-level implementation...

Reliable Communication in Distributed Computer-Controlled Systems

Controller Area Network (CAN) is a fieldbus network suitable for small-scale Distributed Computer Controlled Systems, being appropriate for transferring short real-time messages. However, CAN networks are also known to present some reliability problems, which can lead to an inconsistent message delivery, thus to an unreliable behaviour of the supported applications. In this paper, a set of atom...

An Architecture for Reliable Distributed Computer-Controlled Systems

In Distributed Computer-Controlled Systems (DCCS), both real-time and reliability requirements are of major concern. Architectures for DCCS must be designed considering the integration of processing nodes and the underlying communication infrastructure. Such integration must be provided by appropriate software support services. In this paper, an architecture for DCCS is presented, its structure...

Distributed Computer Systems

Ideas derived from social simulation models can directly inform the design of distributed computer systems. This is particularly the case when systems are “open”, in the sense of having no centralised control, where traditional design approaches struggle. In this chapter we indicate the key features of social simulation work that are valuable for distributed systems design. We also discuss the ...
