While 5GPPP has identified smart manufacturing as one of the most important vertical industries, there is still a lack of specific, practical use cases. \r\n\r\nUsing the experience from a large-scale manufacturing company, Weidm{\\\"u}ller Group, we present a detailed use case that reflects the needs of real-world manufacturers. We also propose an architecture with specific network services and virtual network functions (VNFs) that realize the use case in practice. As a proof of concept, we implement the required services and deploy them on an emulation-based prototyping platform. Our experimental results indicate that a fully virtualized smart manufacturing use case is not only feasible but also reduces machine interconnection and configuration time and thus improves productivity by orders of magnitude." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Daniel full_name: Behnke, Daniel last_name: Behnke - first_name: Müller full_name: Marcel, Müller last_name: Marcel - first_name: Patrick-Benjamin full_name: Bök, Patrick-Benjamin last_name: Bök - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Peuster M, Behnke D, Marcel M, Bök P-B, Karl H.

They allow to dynamically steer traffic\r\nthrough the network when new network functions are instantiated, or old ones\r\nare terminated. These scenarios become in particular challenging when stateful functions are involved, necessitating state management solutions to migrate\r\nstate between the functions. The problem with existing solutions is that they typically embrace state migration and flow rerouting jointly, imposing a huge set\r\nof requirements on the on-boarded virtualized network functions (VNFs), eg,\r\nsolution-specific state management interfaces.\r\nTo change this, we introduce the seamless handover protocol (SHarP). An\r\neasy-to-use, loss-less, and order-preserving flow rerouting mechanism that is\r\nnot fixed to a single state management approach. Using SHarP, VNF vendors\r\nare empowered to implement or use the state management solution of their\r\nchoice. SHarP supports these solutions with additional information when flows\r\nare migrated. In this paper, we present SHarP's design, its open source prototype\r\nimplementation, and show how SHarP significantly reduces the buffer usage at\r\na central (SDN) controller, which is a typical bottleneck in state-of-the-art solutions. Our experiments show that SHarP uses a constant amount of controller\r\nbuffer, irrespective of the time taken to migrate the VNF state." article_number: e2067 author: - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Hannes full_name: Küttner, Hannes last_name: Küttner - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: Peuster M, Küttner H, Karl H.

To optimally utilize the limited computing power and data rate in WASNs, the MARVELO (Multicast-Aware Routing for Virtual network Embedding with Loops in Overlays) framework is expanded for use with TRINICON, while a feature-based selection scheme is proposed to exploit the most beneficial parts of the input signal for adapting the demixing system. The simulation results of realistic scenarios show only a minor degradation of the separation performance even in heavily resource-limited situations. author: - first_name: Michael full_name: Guenther, Michael last_name: Guenther - first_name: Haitham full_name: Afifi, Haitham id: '65718' last_name: Afifi - first_name: Andreas full_name: Brendel, Andreas last_name: Brendel - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl - first_name: Walter full_name: Kellermann, Walter last_name: Kellermann citation: ama: 'Guenther M, Afifi H, Brendel A, Karl H, Kellermann W.

Traditional protocols rely on finding a routing path between sensors generating data and sinks acting as gateway or databases. Meanwhile, the network will suffer from high collisions in case of high data rates. In this context, in-network processing solutions are used to leverage the wireless nodes' computations, by distributing processing tasks on the nodes along the routing path. Although in-network processing solutions are very popular in wired networks (e.g., data centers and wide area networks), there are many challenges to adopt these solutions in wireless networks, due to the interference problem. In this paper, we solve the problem of routing and task distribution jointly using a greedy Virtual Network Embedding (VNE) algorithm, and consider power control as well. Through simulations, we compare the proposed algorithm to optimal solutions and show that it achieves good results in terms of delay. Moreover, we discuss its sub-optimality by driving tight lower bounds and loose upper bounds. We also compare our solution with another wireless VNE solution to show the trade-off between delay and symbol error rate. author: - first_name: Haitham full_name: Afifi, Haitham id: '65718' last_name: Afifi - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Afifi H, Karl H.
