Abstract
This paper is in continuation to our previous work “Improving flexibility and fault-management in CAN-based “Shared-Clock” architectures”, published in the Journal of Microprocessors and Microsystems (Volume 37, 2013, issue 1, pages 9-23) which was concerned with fault-management on embedded level. In this paper, we intend to show that the use of a Port Guardian (PG) mechanism can also improve fault-management on system’s level.
