“…[Vandewoude and Berbers 2002] contains a detailed study of several approaches to dynamic updates and concludes that none of these approaches are directly applicable to updating real-time systems. The study also concludes that componentbased architectures are particularly well-suited for updating real-time systems, which is also confirmed by other authors later on [Gracioli andFröhlich 2008, Soules et al 2003] as well as in the present article.…”

“…The communication layer is however more rigid as it guarantees isolation between components. The K-42 [IBM 2009, Soules et al 2003] and the EPOS [Gracioli and Fröhlich 2008] OSes are such systems: they allow for updates of kernel objects/components at runtime.…”

“…Some of the existing solutions propose to modify the operating system (OS) to enable dynamic updates ( [Gracioli and Fröhlich 2008]). However, to achieve certifications and for business reasons, companies often use commercial offthe-shelf (COTS) operating systems (OSes) and cannot alter low-level mechanisms for the development of commercial highly-available systems.…”

Seamlessly updating software in running systems has recently gained momentum. Dynamically updating the software of real-time embedded systems, however, still poses numerous challenges: such systems must meet hard deadlines, cope with limited resources, and adhere to high safety standards.This paper presents a solution for updating componentbased cyclic embedded systems without violating real-time constraints. In particular, it investigates how to identify points in time at which updates can be performed and how to transfer the state of a component to a new version of the same component. We also present experimental results to validate the proposed solution.

Higher interconnectivity among devices, machines, the cloud and humans is envisioned in the actual trend of automation, also known as Industrial Internet of Things (IIoT). These industrial control systems, which may require high availability and/or safety related capabilities, are no longer isolated from the corporate environment or Internet. Software updates will be needed during the product life cycle, due to the long service life, the increasing number of security related vulnerabilities discovered on these industrial control systems and the high interconnectivity desired in IIoT. These updates aim at fixing all these security weaknesses, bugs and vulnerabilities that could appear, while the required safety integrity levels are ensured. Security-related concerns have just been addressed by the safety engineering community, because of the increasing number of cyber-attacks against safety-critical systems, such as Stuxnet. Moreover, system shut-downs caused by software updates could not be plausible when high availability is required. Typically, in order to perform the software update, the whole industrial process or the production is halted, so that the software upgrade is safely applied. However, this scenario might not be applied in critical infrastructures, such as nuclear or hydroelectrical power plants, where these production and service interruptions are not acceptable from the business and service point of view. This article presents an analysis of existing dynamic software updating techniques, which may be applied for safe and secure industrial control systems. These techniques aim at updating the running code, without the need of a halt and restart, increasing the availability of the industrial system.

Application update at run-time remains a challenging issue in software engineering. There are many techniques with different evaluation metrics, resulting in different behaviours in the application being updated. In this paper, we provide an extensive review of research work on dynamic software updating. A framework for the evaluation of dynamic updating features is developed, and the articles are categorized and discussed based on the provided framework. Areas of online software maintenance requiring further research are also identified and highlighted. This information is deemed to not only assist practitioners in selecting appropriate dynamic updating techniques for their systems, but also to facilitate the ongoing and continuous research in the field of dynamic software updating.
