|---|---|---|
This survey addresses the question if existing realtime capable Internet technologies for wired communication can meet the requirements of future industrial IoT scenarios with a rising number of heterogeneous devices to be connected and increasing amounts of data to be exchanged in real-time. The development towards an industrial IoT is further referred to as Industry 4.0 in Germany and Industrial Internet in the USA, respectively. We first investigate selected widespread technologies at all layers of the ISO/OSI model with respect to their realtime capability, scalability and dynamic reconfiguration, standard compliance and platform complexity as well their capability to integrate non-real-time devices. On the one hand, we note that TSN technology at physical and link layer is standardized but exhibits very high platform complexity for the switches and is thus costly. Subsequently, it is hence discussed if purely software-based approaches can enable RT communication over Ethernet. Moreover, even though TSN-enabled network components can enforce real-time behavior, scheduling and routing algorithms for computing the respective network configuration are not part of the TSN standards. Those algorithms could be executed on a central SDN controller to achieve high performance and realtime capability, however, the scalability of such a centralized approach is limited by the fact that corresponding algorithms have exponential computational complexity. Hence, one of the future research directions outlined proposes to trade off distributed against centralized scheduling and routing approaches with regard to scalability and dynamic reconfiguration, real-time capability, and platform complexity. We conclude there is a need for the advancement of existing and for the development of new, possibly hybrid, real-time capable approaches that combine the advantages of centralized and distributed solution in order to meet all requirements. |
