“…Specific cases of requirements for industrial use are analyzed in [ 41 ], focusing on solutions that have employed SDN, which allowed the authors to determine the satisfaction degree of each requirement through this network technology. The conclusions of this work result are interesting as they shed some light on the industrial network requirements that may be satisfied by SDN, for example, independence of network technologies, reconfiguration during runtime, safety, and security.…”

The use of Software-Defined Networking (SDN) in the communications of the Industrial Internet of Things (IIoT) demands more comprehensive solutions than those developed to date. The lack of an SDN solution applicable in diverse IIoT scenarios is the problem addressed in this article. The main cause of this problem is the lack of integration of a set of aspects that should be considered in a comprehensive SDN solution. To contribute to the solution of this problem, a review of the literature is conducted in this article, identifying the main requirements for industrial networks nowadays as well as their solutions through SDN. This review indicates that aspects such as security, independence of the network technology used, and network centralized management can be tackled using SDN. All the advantages of this technology can be obtained through the implementation of the same solution, considering a set of aspects proposed by the authors for the implementation of SDNs in IIoT networks. Additionally, after analyzing the main features and advantages of several architectures proposed in the literature, an architecture with distributed network control is proposed for all SDN network scenarios in IIoT. This architecture can be adapted through the inclusion of other necessary elements in specific scenarios. The distributed network control feature is relevant here, as it prevents a single fault-point for an entire industrial network, in exchange for adding some complexity to the network. Finally, the first ideas for the selection of an SDN controller suitable for IIoT scenarios are included, as this is the core element in the proposed architecture. The initial proposal includes the identification of six controllers, which correspond to different types of control planes, and ten characteristics are defined for selecting the most suitable controller through the Analytic Hierarchy Process (AHP) method. The analysis and proposal of different fundamental aspects for the implementation of SDNs in IIoT in this article contribute to the development of a comprehensive solution that is not focused on the characteristics of a specific scenario and would, therefore, be applicable in limited situations.

“…QoS and real-time timing guarantees (R1-R2), using the existing southbound API. Ehrlich et al [8] present a similar study, identifying a set of ten requirements of future industrial network management frameworks (a super-set of R1-R5) and comparing against the current capabilities of SDN. They conclude that SDN fulfills a subset of the requirements, namely independence from underlying network technologies, support for online (re)configurations, and security-related features (essentially R3-R5), but still fails in several aspects such as the inability to set QoS provisioning and monitoring (R1-R2) due to unsuitable southbound APIs.…”

“…In this paper, we contribute to close such a gap by extending SDN with adequate real-time mechanisms. The related scientific literature [6]- [8] reports the use of SDN on industrial networks but at the conceptual level, only, under simulated or emulated scenarios, with limitations in scalability, predictability and/or flexibility [7]. The work in [9] appears to be the first step to add explicit support for flexible realtime communication within SDN by leveraging the flexibility of HaRTES real-time Ethernet switches.…”

A Real-Time Software Defined Networking Framework for Next-Generation Industrial Networks

Industry 4.0 brings in a whole set of new requirements to engineering industrial systems, with notorious impact at the networking layer. A key challenge posed by Industry 4.0 is the operational flexibility needed to support on-the-fly reconfiguration of production cells, stations, and machines. At the networking layer, this flexibility implies dynamic packet handling, scheduling, and dispatching. Software-Defined Networking (SDN) provides this level of flexibility in the general Local Area Network (LAN) domain. However, its application in the industry has been hindered by a lack of support for real-time services. This paper addresses this limitation, proposing an extended SDN OpenFlow framework that includes realtime services, leveraging existing real-time data plane Ethernet technologies. We show the OpenFlow enhancements, a real-time SDN controller, and experimental validation and performance assessment. Using a proof-of-concept prototype with 3 switches and cycles of 250µs, we could achieve 1µs jitter on timetriggered traffic and a reconfiguration time between operational modes below 10ms. INDEX TERMS HaRTES, Industry 4.0, OpenFlow, real-time communications, software-defined networking.

“…Moreover, the standard defines alternative network configuration and management schemes that leverage SRP. Several studies are suggesting that complementing the TSN with a networking concept such as software-defined networks, SDN, is a beneficial configuration solution [4], [5], [18]. With additional protocols (e.g., Netconf and Openflow), SDN allows for instant configuration of routes and transport schedules based on a central control plane [10].…”

The convergence of Information Technology (IT) and Industrial Operations Technology (OT) results in efficient network management solutions for automotive and industrial automation environments. However, configuring real-time Ethernet networks while maintaining the desired QoS is challenging due to the dynamic nature of OT networks and the high number of configuration parameters. This paper introduces a Software-Defined Network (SDN)-based self-configuration framework for the time-sensitive networks (TSNs). Unlike standard TSN, we remove end-host-related dependencies and put streams initially on default paths to extract traffic characteristics by monitoring network traffic at edge switches. Communicated to a central SDN controller, these characteristics allow moving streams to optimal paths while maintaining hard real-time guarantees, for which we also formulate an optimization problem. According to the results, although the proposed approach increases the average delay of critical frames by less than 1%, a certain level of realtime guarantee can be provided without prior knowledge of the streams.
