Implementing virtual platform for global-scale cyber physical system networks

The need for global-scale cyber physical system (CPS) is increasing with the evolution of CPS research. A global-scale CPS requires additional considerations beyond the well-known CPS requirements, such as security, reliability, and timely delivery, which cannot be easily satisfied when a CPS becomes global scale. Building an entire dedicated network for a global-scale CPS cannot be a solution, because it requires a large capital outlay in order to be actualized. To overcome these obstacles, we implement a virtual platform named Xebra that includes effective CPS middleware for realizing a global-scale CPS and isolation techniques based on virtualization. In this paper, we discuss the requirements for realizing global-scale CPS network, and also, we introduce our implementation as a virtual platform with its performance evaluation.
