This paper presents a new fault-tolerant c … This paper presents a new fault-tolerant clock synchronization algorithm designed for the Controller Area Network (CAN). The algorithm provides all correct processes
of the system with a global timebase, despite the occurrence
of faults in the network or in a minority of processes. Such
global time-frame is a requirement of many distributed real-
time control systems.
Designing protocols for CAN is justified by the increasing use of this network in industrial automation applications. CAN owns a number of unique properties that can
be used to improve the precision and performance of a
clock synchronization algorithm. Unfortunately, some of its
features also make the implementation of a fault-tolerant
clock synchronization service a non-trivial task. Our algorithm addresses both the positive and the negative aspects
of CAN. positive and the negative aspects
of CAN.
