“…Guaranteeing service-level real-time in a CAN-based networked control system is also studied [44]. There are several research works on synchronization between distributed controllers [45,46,47,48]. In this paper, we especially aim to adjust the phase offsets of virtual controllers and their tasks by means of the global clock and improve the worst-case end-to-end delay.…”

The virtualization technology has a great potential to improve the manageability and scalability of industrial control systems, as it can host and consolidate computing resources very efficiently. There accordingly have been efforts to utilize the virtualization technology for industrial control systems, but the research for virtualization of traditional industrial real-time networks, such as Controller Area Network (CAN), has been done in a very limited scope. Those traditional fieldbuses have distinguished characteristics from well-studied Ethernet-based networks; thus, it is necessary to study how to support their inherent functions transparently and how to guarantee Quality-of-Service (QoS) in virtualized environments. In this paper, we suggest a lightweight CAN virtualization technology for virtual controllers to tackle both functionality and QoS issues. We particularly target the virtual controllers that are containerized with an operating-system(OS)-based virtualization technology. In the functionality aspect, our virtualization technology provides virtual CAN interfaces and virtual CAN buses at the device driver level. In the QoS perspective, we provide a hierarchical real-time scheduler and a simulator, which enable the adjustment of phase offsets of virtual controllers and tasks. The experiment results show that our CAN virtualization has lower overheads than an existing approach up to 20%. Moreover, we show that the worst-case end-to-end delay could be reduced up to 78.7% by adjusting the phase offsets of virtual controllers and tasks.

“…But it is also a basic abstraction on which it is possible to build models of computation, communication services, and fault tolerant algorithms [13]. Distributed architectures that make use of the time-triggered model of computation, for example, are built over a strict clock synchronization service [14].…”

This paper reports a study and practical evaluation of two different clock synchronization methods for distributed measurement and control nodes based on Linux Single Board Computers (SBCs) with ARM processors and communicating through a TCP/IP wide area network. First the Network Time Protocol (NTP) is configured and evaluated in different network scenarios. The second solution is a specific development for Global Positioning System (GPS) clock synchronization. After a description of the hardware and software implementation of this solution the experimental results are reported and commented.

“…However, fieldbuses have not been studied thoroughly in the context of IMA architecture. Though there have been significant researches on real-time and synchronization issues over fieldbuses [5,6,4,18,8,15], still we need to address several issues to utilize fieldbuses on the IMA architecture.…”

Fieldbus virtualization for Integrated Modular Avionics

The architecture of avionics systems is moving from federated to integrated architecture called Integrated Modular Avionics (IMA). In the IMA architecture, several avionics applications can be transparently integrated on the same computing device and communicate with others without knowing whether others are running on the same node or not. However, the fieldbuses have not been studied thoroughly in the context of IMA architecture though they are quite attractive for implementing avionics data bus. In this paper, we propose a novel design of device-level virtualization to utilize Controller Area Network (CAN) efficiently on various implementations of the IMA architecture. Our proposed device-level virtualization provides virtual CAN devices and emulates the characteristics of CAN bus. We also deal with the issues to support the communication modes defined by ARINC 653. 1
