Estimating the Influence of SDN Controller Intervention on Smart Grid Services

The integration of Software Defined Networking (SDN) to manage Smart Grid Services (SGSs) has raised concerns about its impact on the end-to-end response times in the system. This paper investigates the Quality of Service (QoS) of SGSs in SDN environments using Constraint Satisfaction Problem (CSP) and Network Calculus (NC) techniques. Our studies show that the implementation of SDN contributes to an increase in end-to-end delay times and negatively affects the QoS of SGSs. These results provide insights for designing more efficient and reliable energy systems with SDN environments.
