Implementació i Testeig de l'Esquema de Replicació de Nodes de l'Arquitectura FT4FTT

Abstract

[eng] Distributed Embedded Control Systems (DECSs) typically have stringent real-time and dependability requirements. Moreover, nowadays they are starting to be deployed in dynamic environments where they must also be flexible to adapt to the unexpected changes in the operation conditions. The FT4FTT project aims at providing an architecture for a complete distributed embedded system which supports applications that are real-time, highly-reliable and adaptive. This project addresses all these requirements for both the network and the nodes of the DECS. In this work we describe the implementation and testing of the fault-tolerance mechanisms devised to provide the nodes with tolerance to permanent and temporary faults, as well as to recover a faulty node when a temporary fault provokes its permanent discoordination with the rest of the system.
