First of all, an overview of the EKU Power Drives GmbH system to be synchronized is given. Afterwards, the necessary basics will be discussed and an introduction into possible protocols for time synchronization will be given. Based on a weighting table, the most appropriate protocol for the present case should finally be selected. In addition, the peculiarities of the used software stack for the electronic control units are described and the used hardware in the system and also for the prototype setup described. The following chapter details the selected time synchronization protocol and then take a closer look at the prototype construction. The implementation of the protocol and the steps required to port the software as well as the difficulties involved will be shown in the next chapter. In the concluding chapters, the evaluation will then be based on measurement data and a conclusion will be drawn before giving an outlook on the extension and optimization of the system.NeSTiNg: Simulating IEEE Time-sensitive Networking (TSN) in OMNeT++https://puma.ub.uni-stuttgart.de/bibtex/27cdec90ccc4740492b9721817d1aa291/ben.carabelliben.carabelli2019-12-16T16:17:21+01:00Ethernet OMNeT++ TSN myown network networking real-time simulation time-sensitive <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Jonathan Falk" itemprop="url" href="/person/1793c449414fc98379aef558235ff9bea/author/0"><span itemprop="name">J.

In particular, TSN specifies a time-triggered scheduling mechanism in IEEE Std 802.1Qbv implemented by switches to control when outgoing queues get access to switch ports. Besides this time-triggered scheduling mechanism, other scheduling mechanisms can be active in the network at the same time including priority queuing and a credit-based shaper. Moreover, further supporting mechanisms such as the possibility to interrupt frames already in transmission (frame preemption) are specified by the TSN standards. Overall, this leads to a complex network infrastructure transporting both, real-time and non-real-time traffic in one converged network, making it hard to analyze the behavior of converged networks. To facilitate the analysis of TSN networks, we present TSN-specific extensions to the popular OMNeT++/INET framework for network simulations in this paper including, in particular, the time-triggered scheduling mechanism of IEEE Std 802.1Qbv. Besides the design of the TSN simulator, we present a proof-of-concept implementation and exemplary evaluation of TSN networks.Steuerung und Regelung mit konventionellem Ethernet: Steuerung und Regelung mit konventionellem Ethernethttps://puma.ub.uni-stuttgart.de/bibtex/2580fef5a285c7ed080aa82fcb2a2eab5/isw-bibliothekisw-bibliothek2016-03-03T09:53:12+01:00Automatisierung Echtzeit Ethernet Feldbus ISW xgh <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Oliver Gerlach" itemprop="url" href="/person/12260fb548dc024c75334fe63607415fa/author/0"><span itemprop="name">O.
