INDEPTH: Timeliness Assessment of Ethernet/IP-based Systems
Ref: HURRAY-TR-0433       Publication Date: 4, Oct, 2004

Abstract:
The continuous improvement of Ethernet technologies is boosting the eagerness of extending their use to also cover factory-floor distributed real time applications. Indeed, it is remarkable the considerable amount of research work that has been devoted to the timing analysis of Ethernet-based technologies in the past few years. It happens, however, that the majority of those works are restricted to the analysis of sub-sets of the overall computing and communication system, thus without addressing timeliness in a holistic fashion. To this end, in this paper we address an approach, based on simulation, aiming at extracting temporal properties of Commercial-Off-The-Shelf (COTS) Ethernet-based factory-floor distributed systems. This framework is being applied to a specific COTS technology, Ethernet/IP. In this paper, we reason about the modeling and simulation of Ethernet/IP-based systems, and on the use of statistical analysis techniques to provide useful results on timeliness.
