In recent years, smart factory in the context of Industry 4.0 and Industrial Internet of Things (IIoT) has become a hot topic for both academia and industry. In IIoT system, there is an increasing requirement for exchange of data with different delay flows among different smart devices. However, there are few studies on this topic. To overcome the limitations of traditional methods and address the problem, we seriously consider the incorporation of global centralized Software Defined Network (SDN) and Edge computing in IIoT with edge computing. A major challenge in the design of these mobile systems will be the provision of the quality of service (QoS) guarantees that the applications demand under this diverse networking infrastructure. Software-defined networking in smart factories (SF) enables them to easily adapt the communication network to changing requirements Similar to cloud-based systems, such SFs could be seen as production clusters that could be rented and configured as needed. The SF network utilizes software-defined networking (SDN) combined with network functions virtualization (NFV) in order to achieve the required flexibility. Despite the fact that the technology is nowadays not yet ready for deployment in todays manufacturing networks, a novel network architecture for SFs based on SDN and network virtualization in order to support smart services especially for Industrie 4.0. We believe that it is necessary to use resource reservation and adaptation schemes to deliver these QoS guarantee to applications, using the user mobility pattern. If the movement of a user is known, the reservation and configuration procedure can be limited to the regions of the network a user is likely to visit. (C) 2018 The Authors.
