SD-CPS: Taming the challenges of Cyber-Physical Systems with a Software-Defined approach

Abstract

Cyber-Physical Systems (CPS) revolutionize various application domains with integration and interoperability of networking, computing systems, and mechanical devices. Due to its scale and variety, CPS faces a number of challenges and opens up a few research questions in terms of management, fault-tolerance, and scalability. We propose a software-defined approach inspired by Software-Defined Networking (SDN), to address the challenges for a wider CPS adoption. We thus design a middleware architecture for the correct and resilient operation of CPS, to manage and coordinate the interacting devices centrally in the cyberspace whilst not sacrificing the functionality and performance benefits inherent to a distributed execution.

Database Bundle System with High Availability: Employing Message-Oriented Intermediary Software

“…Additionally, these systems have complex architectures, resulting in high development and maintenance costs.Furthermore, existing database bundles generally perform poorly in terms of network fault tolerance, particularly at the TCP connection level. 6 While Oracle RAC has some TCP fault tolerance capabilities, this technology is proprietary. In contrast, the present invention proposes a high-availability database bundle system based on messageoriented intermediary software, which effectively addresses all the issues.…”

Modeling cooperative behavior for resilience in cyber-physical systems using SDN and NFV

“…Our current work is similar to [48] except the latter is concerned with energy efficiency and the former is towards the more efficient coordination among virtualized agents for supporting the CPS resilience in a more generic way. In addition [49], is about a software-defined solution but without NFV. The authors of [50] revise the literature on software-based (i.e.…”
