Toward Edge-enabled Cyber-Physical Systems Testbeds

Abstract: The use of edge computing can be extremely valuable in support of CPS efforts. However, few if any testbeds provide the type of resource control and provisioning required to support edge-enabled CPS experimentation. Likewise, commercial offerings provide operational capabilities, but lack the distributed infrastructure and transparency provided by research testbed. In this paper we propose methods to develop new and augment existing testbeds to better support the challenges of edge computing and CPS research. The proposed network is specifically designed to address the challenges associated with edge-based provisioning, data collection, analysis, monitoring, and measurement across islands of edge and data center resources. We present the purpose of our work, the basic architecture, initial results, the relationship to the existing software, and the potential of an existing edge-focused framework to support the foundations of edge-focused CPS testbeds.
