Abstract

Distributed embedded systems typically have real-time and dependability requirements. Moreover, they must also be flexible to changing conditions when they are deployed in dynamic environments. The FT4FTT project aims at providing a switched Ethernet architecture that can support distributed control applications that are predictable, highly-reliable and adaptive. FT4FTT relies on the Flexible Time-Triggered Replicated Star for Ethernet (FTTRS) to tolerate channel faults. Moreover, nodes’ hardware faults are tolerated by means of active node replication with majority voting. In order to coordinately trigger the execution of the tasks in the replicas, we designed the CD4NR mechanism, in which the network assists in deciding what to execute and when. This paper presents the first implementation of the CD4NR mechanism on a real prototype of FTTRS and the first testing of the complete system. For this we developed an experimental setup, based on the hardware-in-the-loop technique, running a real-time control application.
