Challenges and Future Direction of Time-Sensitive Software-Defined Networking (TSSDN) in Automation Industry

In Industry 4.0, Cyber physical system (CPS) is suffered from queuing delay during the process of data gathering and feedback generation by which affects the efficiency of providing hard real-time guarantees. Hard real-time cyber physical system requires software and hardware to operate strictly within the deadline. Time-Sensitive Software-Defined Networking (TSSDN) is an architecture which utilizes the centralized network controller in Software-Defined Networking (SDN) to facilitate the operation of software and hardware in CPS globally. Time-sensitive-aware scheduling traffic system in TSSDN is capable to minimize the queuing delay in the network which leads to hard real-time guarantees. Hence, the potential opportunities of TSSDN in automation industry has motivate the further investigate of its current states. This paper will discuss the challenges of TSSDN and suggest its future direction enhancement
