    The advances in industrial automation systems rise more stringent demands for reliable and flexible communication. 5G and TSN have been discussed widely as promising candidates that fulfil these requirements. To take advantage of the combination of both of these technologies, an integration of 5G with TSN is part of the current work on the 5G specifications.In this paper, a simulation approach for OMNeT++ based on the existing TSN model NeSTiNg and a novel lightweight 5G user plane model that is still under development is presented. By means of a relevant closed loop control simulation, the known issue of different scheduling periods is reproduced in a minimal simulation scenario. Furthermore, crucial further steps to optimize the model towards an IEEE 802.1Qbv TSN bridge are identified as future tasks.

    Industrial applications in the era of Industry 4.0 require more exibility for the integration of new sensors and actuators and also demand high mobility for which wired communication is unsuitable. For the integration of wireless communication systems in an industrial application, guaranteed high Quality of Service (QoS) is a premise that is not fully covered by wireless systems such as WiFi, Bluetooth, ZigBeeor LTE. For the latter, the evolution to 5G systems as private or public networks is a currently ongoing process. This paper examines the legal and technical requirements to operate a private mobile cell in a smart factory and presents measurements on latency and bandwidth performance of current state of the art hardware as well as the integration in an industrial Layer 2 communication system. The system in use is ready for only low demanding industrial real-time applications but, nevertheless, the advantages of a licensed frequency range for private use become visible. Furthermore, some concepts dened by the 3GPP, e.g. mini-slots and grant free transmission, are pointed out that are expected to enhance the QoS guarantees for industrial traffic.

    Today many hybrid (wired & wireless) industrial communication networks with a huge variety of heterogeneous technologies and protocols are present in the manufacturing and automation domain. The increasing requirements regarding e. g., latency, reliability, or determinism create the need for a holistic network management concept in order to assure a network-wide Quality-of-Service (QoS) resource provisioning and the assurance of the admissioned resources. Consequently, a monitoring of the whole network is required to feed the network management system with the needed information about the underlying network processes. Various technical approaches using different methods of extracting the information from network traffic are available for the purpose of QoS parameter observance and measurement at the moment. Therefore, this paper provides a state of the art research about network management and QoS provisioning respectively QoS assurance concepts. In addition, the passive network monitoring approach using the flow export technique based on the Internet Protocol Flow Information Export (IPFIX) is investigated for a utilisation in the nowadays industry domain based on a conceptual case study with a wireless protocol. As a conclusion, an evaluation is performed in order to clarify the limits and the overall usability of IPFIX for the monitoring of industrial networks in order to support future network management systems.

    The upcoming fifth generation of mobile networks (5G) is supposed to enable innovation in industries like factory and process automation by addressing machine-type communication and its requirements of reliability and latency. However, 5G will not immediately fulfill all the requirements raising from industrial applications at reasonable costs. The integration of 5G as a network entity into an industrial communication system is therefore considered as an applicable migration path. In this paper, a flexible and adaptive integration of a 5G mobile network into the industrial Ethernet protocol Profinet utilizing the network slicing concept will be proposed.

    In contrast to the predecessors, the fifth generation of mobile networks (5G) will particularly address communication in production systems by providing machine-type communication and matching requirements regarding reliability and latency. However, 3GPP 5G will not be the one and only network technology that can be used to fulfill all the requirements raising from industrial applications at reasonable costs. It is more likely, that it complements other wired and wireless technologies, rather than replacing them. This paper presents different scenarios to combine 5G and Industrial Ethernet to a hybrid topology, it explains the characteristics and possible use cases for these scenarios and it sketches approaches to engineer and configure the hybrid network.

    Nowadays, industrial networks are characterized by complex architectures of hybrid, wired and wireless segments, combining automation and information technology (IT). Their operation is supported by network management facilities. Network monitoring is a basis for management as it provides the necessary status information. This paper presents an approach to apply a monitoring concept coming from the IT domain for an industrial wireless network as a step towards a uniform monitoring and management of heterogeneous networks.

    Electrical and electronic systems have been getting raising importance for innovations in the automotive industry. Networking issues are a key factor in this process since they enable distributed control functions and user interaction bringing together nodes from different vendors. This paper analyses available and emerging network technologies for in-vehicle communication from a requirements driven perspective. It reviews successful network technologies from other application areas regarding a possible deployment in vehicular communication and distinguishes passenger car and commercial vehicle sectors as far as possible. This contribution is oriented to the OSI reference model showing the state of the art and future opportunities at the level of the several communication layers with a focus on physical layer issues and medium access protocols and including information modeling aspects.
