Typically, frequency bands were assumed to be available in a stable manner. Nevertheless, in recent scenarios where wireless networks may be deployed in unknown environments, spectrum competition is considered, making it uncertain whether a frequency band is available at all or at what quality. To fully exploit such resources with uncertain availability, the multi-armed bandit (MAB) method, a representative online learning technique, has been applied to design spectrum scheduling algorithms. This article surveys such proposals. We describe the following three aspects: how to model spectrum scheduling problems within the MAB framework, what the main thread is following which prevalent algorithms are designed, and how to evaluate algorithm performance and complexity. We also give some promising directions for future research in related fields.","lang":"eng"}],"status":"public","date_created":"2020-03-10T16:02:30Z","publication_status":"published","publication_identifier":{"issn":["1536-1284","1558-0687"]},"author":[{"full_name":"Li, Feng","first_name":"Feng","last_name":"Li"},{"last_name":"Yu","first_name":"Dongxiao","full_name":"Yu, Dongxiao"},{"first_name":"Huan","full_name":"Yang, Huan","last_name":"Yang"},{"full_name":"Yu, Jiguo","first_name":"Jiguo","last_name":"Yu"},{"first_name":"Holger","full_name":"Karl, Holger","last_name":"Karl","id":"126"},{"last_name":"Cheng","first_name":"Xiuzhen","full_name":"Cheng, Xiuzhen"}],"department":[{"_id":"75"}],"publication":"IEEE Wireless Communications"},{"conference":{"name":"IEEE Conference on Network Softwarization (NetSoft) Demo Track","location":"Ghent, Belgium"},"_id":"16400","date_updated":"2022-01-06T06:52:50Z","language":[{"iso":"eng"}],"type":"conference","year":"2020","citation":{"chicago":"Müller, Marcel, Daniel Behnke, Patrick-Benjamin Bök, Stefan Balthasar Schneider, Manuel Peuster, and Holger Karl. “Cloud-Native Threat Detection and Containment for Smart Manufacturing.” In IEEE Conference on Network Softwarization (NetSoft) Demo Track.

Finally, we demonstrate the proposed concepts and solutions in a case study using our open-source prototype to test and profile a chained network service."}],"user_id":"477","ddc":["000"],"file":[{"relation":"main_file","date_updated":"2019-02-26T18:09:43Z","content_type":"application/pdf","file_id":"8114","creator":"peuster","file_size":232599,"access_level":"open_access","file_name":"main_for_ris.pdf","date_created":"2019-02-26T18:09:43Z"}],"publication":"ICT Express","file_date_updated":"2019-02-26T18:09:43Z","publisher":"Elsevier BV","author":[{"last_name":"Peuster","id":"13271","first_name":"Manuel","full_name":"Peuster, Manuel"},{"last_name":"Dröge","first_name":"Christian","full_name":"Dröge, Christian"},{"last_name":"Boos","full_name":"Boos, Clemens","first_name":"Clemens"},{"id":"126","last_name":"Karl","full_name":"Karl, Holger","first_name":"Holger"}],"date_created":"2019-02-26T18:07:33Z","status":"public","has_accepted_license":"1","date_updated":"2022-01-06T07:03:51Z","oa":"1","doi":"10.1016/j.icte.2019.02.001","language":[{"iso":"eng"}],"title":"Joint testing and profiling of microservice-based network services using TTCN-3","department":[{"_id":"75"}],"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"},{"_id":"28","grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps"}],"publication_identifier":{"issn":["2405-9595"]},"publication_status":"published"},{"publication_status":"accepted","project":[{"_id":"23","name":"5G Programmable Infrastructure Converging disaggregated neTwork and compUte Resources","grant_number":"762057"},{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"date_created":"2019-03-04T09:23:54Z","status":"public","department":[{"_id":"75"}],"publication":"5th IEEE International Conference on Network Softwarization (NetSoft) 2019","author":[{"id":"31764","last_name":"Dräxler","full_name":"Dräxler, Sevil","first_name":"Sevil"},{"id":"126","last_name":"Karl","full_name":"Karl, Holger","first_name":"Holger"}],"title":"SPRING: Scaling, Placement, and Routing of Heterogeneous Services with Flexible Structures","user_id":"31764","type":"conference","year":"2019","citation":{"short":"S.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"oa":"1","doi":"10.1002/nem.2067","date_updated":"2022-01-06T07:04:01Z","project":[{"_id":"28","name":"5G Development and validation platform for global industry-specific network services and Apps","grant_number":"761493"},{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"publication_status":"published","publication_identifier":{"issn":["1055-7148","1099-1190"]},"department":[{"_id":"75"}],"title":"A flow handover protocol to support state migration in softwarized networks"},{"title":"Empowering Network Service Developers: Enhanced NFV DevOps and Programmable MANO","user_id":"13271","publication_identifier":{"issn":["0163-6804","1558-1896"]},"publication_status":"published","status":"public","date_created":"2019-05-16T09:07:19Z","project":[{"_id":"28","grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps"}],"author":[{"first_name":"Thomas","full_name":"Soenen, Thomas","last_name":"Soenen"},{"last_name":"Tavernier","first_name":"Wouter","full_name":"Tavernier, Wouter"},{"full_name":"Peuster, Manuel","first_name":"Manuel","id":"13271","last_name":"Peuster"},{"first_name":"Felipe","full_name":"Vicens, Felipe","last_name":"Vicens"},{"last_name":"Xilouris","first_name":"George","full_name":"Xilouris, George"},{"first_name":"Stavros","full_name":"Kolometsos, Stavros","last_name":"Kolometsos"},{"first_name":"Michail-Alexandros","full_name":"Kourtis, Michail-Alexandros","last_name":"Kourtis"},{"last_name":"Colle","full_name":"Colle, Didier","first_name":"Didier"}],"publication":"IEEE Communications Magazine","department":[{"_id":"75"}],"doi":"10.1109/mcom.2019.1800810","_id":"9823","date_updated":"2022-01-06T07:04:22Z","year":"2019","citation":{"ama":"Soenen T, Tavernier W, Peuster M, et al.

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.","lang":"eng"}],"place":"New Paltz, USA","date_created":"2019-07-24T07:25:01Z","project":[{"name":"Akustische Sensornetzwerke - Teilprojekt ","_id":"27"},{"_id":"27","name":"Akustische Sensornetzwerke - Teilprojekt \"Verteilte akustische Signalverarbeitung über funkbasierte Sensornetzwerke"}],"status":"public","department":[{"_id":"75"}],"publication":"2019 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA) (WASPAA 2019)","author":[{"first_name":"Michael","full_name":"Guenther, Michael","last_name":"Guenther"},{"full_name":"Afifi, Haitham","first_name":"Haitham","id":"65718","last_name":"Afifi"},{"first_name":"Andreas","full_name":"Brendel, Andreas","last_name":"Brendel"},{"first_name":"Holger","full_name":"Karl, Holger","last_name":"Karl","id":"126"},{"last_name":"Kellermann","full_name":"Kellermann, Walter","first_name":"Walter"}],"date_updated":"2022-01-06T06:51:22Z","_id":"12880","language":[{"iso":"eng"}],"type":"conference","year":"2019","citation":{"mla":"Guenther, Michael, et al. “Sparse Adaptation of Distributed Blind Source Separation in Acoustic Sensor Networks.” 2019 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA) (WASPAA 2019), 2019.","bibtex":"@inproceedings{Guenther_Afifi_Brendel_Karl_Kellermann_2019, place={New Paltz, USA}, title={Sparse Adaptation of Distributed Blind Source Separation in Acoustic Sensor Networks}, booktitle={2019 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA) (WASPAA 2019)}, author={Guenther, Michael and Afifi, Haitham and Brendel, Andreas and Karl, Holger and Kellermann, Walter}, year={2019} }","chicago":"Guenther, Michael, Haitham Afifi, Andreas Brendel, Holger Karl, and Walter Kellermann. “Sparse Adaptation of Distributed Blind Source Separation in Acoustic Sensor Networks.” In 2019 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA) (WASPAA 2019).

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."}],"title":"An Approximate Power Control Algorithm for a Multi-Cast Wireless Virtual Network Embedding","user_id":"65718","author":[{"id":"65718","last_name":"Afifi","full_name":"Afifi, Haitham","first_name":"Haitham"},{"full_name":"Karl, Holger","first_name":"Holger","id":"126","last_name":"Karl"}],"department":[{"_id":"75"}],"publication":"2019 12th IFIP Wireless and Mobile Networking Conference (WMNC) (WMNC'19)","status":"public","project":[{"name":"Akustische Sensornetzwerke - Teilprojekt \"Verteilte akustische Signalverarbeitung über funkbasierte Sensornetzwerke","_id":"27"}],"date_created":"2019-07-24T07:25:28Z","_id":"12881","date_updated":"2022-01-06T06:51:22Z","type":"conference","citation":{"short":"H.

The aim of MARVELO is to select the nodes for running the algorithms and to define the routing between the nodes. Hence, it also supports monitoring functionalities to collect information about the available resources and to assist in profiling the algorithms. The objective of this demo is to show how MAVRLEO distributes tasks in an ad-hoc network, based on a feedback from our monitoring tool.

This paper studies the scheduling of sensor transmissions to estimate the states of multiple remote, dynamic processes. Information from the different sensors has to be transmitted to a central gateway over a wireless network for monitoring purposes, where typically fewer wireless channels are available than there are processes to be monitored. For effective estimation at the gateway, the sensors need to be scheduled appropriately, i.e., at each time instant one needs to decide which sensors have network access and which ones do not. To address this scheduling problem, we formulate an associated Markov decision process (MDP). This MDP is then solved using a Deep Q-Network, a recent deep reinforcement learning algorithm that is at once scalable and model-free. We compare our scheduling algorithm to popular scheduling algorithms such as round-robin and reduced-waiting-time, among others.

Accordingly, new types of applications take an advantage of the processing and flexibility provided by the wireless network. A common property between these applications is that the processing is not running on only one single node, but it is broken-down into smaller tasks that can run over multiple nodes, i.e., exploiting the in-network processing. We study a special variant of in-network processing, where the application is given by a graph; the processing tasks have predefined connections to be executed in a predefined sequence. The problem of embedding an application graph into a network is commonly known as Virtual Network Embedding (VNE). In this paper, we present a Genetic Algorithm (GA) solution to solve this wireless VNE problem, where we take into account the interference and multi-cast properties. We show that the GA has a good performance and fast execution compared to the optimization problem."}]},{"type":"dissertation","year":"2019","citation":{"short":"S.

In this paper, we describe our experiments for characterizing the relationship between resource demands of virtual network functions (VNFs) and the expected performance of the SFC, considering the individual performance of the VNFs as well as the interdependencies among VNFs within the SFC. We have designed our experiments focusing on video streaming, an important application in this context. We present examples of models for predicting the interdependence between resource demands and performance characteristics of SFCs using support vector regression and polynomial regression models. We also show practical evidence from our experiments that VNFs need to be benchmarked in their final chain setup, rather than individually, to capture important interdependencies that affect their performance.

Current approaches are limited in flexibility and practical applicability. Specifically, we study dynamic, single-step, joint scaling and placement of network services with bidirectional flows traversing Physical or Virtual Network Functions (VNFs) and returning to their sources. We develop models to support stateful components and legacy network functions with fixed locations in these network services as well as the possibility of reusing VNFs across network services. We formalize the problem of jointly scaling and placing such network services as a mixed- integer linear program (MILP). We show that this problem is NP-complete and also present a heuristic algorithm to find good solutions in short time. In an extensive evaluation with realistic scenarios, we investigate the capabilities of the two approaches.","lang":"eng"}],"user_id":"477","ddc":["040"],"file":[{"access_level":"open_access","date_created":"2018-06-25T07:40:57Z","file_name":"RIS.pdf","relation":"main_file","content_type":"application/pdf","date_updated":"2018-06-25T07:40:57Z","file_id":"3319","creator":"sevilmeh","file_size":1471937}],"author":[{"id":"31764","last_name":"Dräxler","full_name":"Dräxler, Sevil","first_name":"Sevil"},{"full_name":"Schneider, Stefan Balthasar","orcid":"0000-0001-8210-4011","first_name":"Stefan Balthasar","id":"35343","last_name":"Schneider"},{"id":"126","last_name":"Karl","full_name":"Karl, Holger","first_name":"Holger"}],"publisher":"IEEE","publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","file_date_updated":"2018-06-25T07:40:57Z","has_accepted_license":"1","status":"public","date_created":"2018-04-24T12:14:00Z","_id":"2481","urn":"24814","conference":{"location":"Montreal","name":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)"},"type":"conference","year":"2018","citation":{"ieee":"S.

This becomes par- ticular challenging when stateful functions are involved, necessi- tating state management. The problem with existing solutions is that they typically embrace state migration and flow rerouting jointly, imposing a huge set of requirements on the on-boarded VNFs, e.g., solution-specific state management interfaces.\r\nIn this paper, we introduce the seamless handover proto- col (SHarP). It provides an easy-to-use, loss-less, and order- preserving flow rerouting mechanism that is not fixed to a single state management approach. This allows VNF vendors to implement or use the state management solution of their choice. SHarP supports these solutions with additional information when flows are migrated. Further, we show how SHarP significantly reduces the buffer usage at a central (SDN) controller, which is a typical bottleneck in existing solutions. Our experiments show that SHarP uses a constant amount of controller buffer, irrespective of the time taken to migrate the VNF state.","lang":"eng"}],"language":[{"iso":"eng"}],"oa":"1","doi":"10.1109/NETSOFT.2018.8460007","date_updated":"2022-01-06T06:59:11Z","project":[{"grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps","_id":"28"},{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"publication_status":"accepted","department":[{"_id":"75"}],"title":" Let the state follow its flows: An SDN-based flow handover protocol to support state migration","place":"Montreal"},{"language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:59:11Z","doi":"10.1109/NETSOFT.2018.8459905","oa":"1","department":[{"_id":"75"}],"publication_status":"accepted","project":[{"_id":"28","name":"5G Development and validation platform for global industry-specific network services and Apps","grant_number":"761493"},{"name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"_id":"16","name":"SFB 901 - Subproject C4"}],"place":"Montreal","title":"Containernet 2.0: A Rapid Prototyping Platform for Hybrid Service Function Chains","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/8459905/"}],"citation":{"short":"M.

In this paper, we propose JASPER, a fully automated approach to jointly optimizing scaling, placement, and routing for complex network services, consisting of multiple (virtualized) components. JASPER handles multiple network services that share the same substrate network; services can be dynamically added or removed and dynamic workload changes are handled. Our approach lets service designers specify their services on a high level of abstraction using service templates. JASPER automatically makes scaling, placement and routing decisions, enabling quick reaction to changes. We formalize the problem, analyze its complexity, and develop two algorithms to solve it. Extensive empirical results show the applicability and effectiveness of the proposed approach."}],"article_type":"original","date_created":"2018-06-11T06:55:05Z","has_accepted_license":"1","status":"public","file_date_updated":"2019-01-21T16:12:36Z","publication":"IEEE Transactions on Network and Service Management","publisher":"IEEE","author":[{"id":"31764","last_name":"Dräxler","full_name":"Dräxler, Sevil","first_name":"Sevil"},{"last_name":"Karl","id":"126","first_name":"Holger","full_name":"Karl, Holger"},{"full_name":"Mann, Zoltan Adam","first_name":"Zoltan Adam","last_name":"Mann"}],"file":[{"file_name":"08382313.pdf","date_created":"2018-11-02T15:25:49Z","access_level":"closed","file_size":1767054,"file_id":"5302","creator":"ups","content_type":"application/pdf","date_updated":"2018-11-02T15:25:49Z","relation":"main_file","success":1},{"relation":"main_file","date_updated":"2019-01-21T16:12:36Z","content_type":"application/pdf","file_id":"6950","creator":"sevilmeh","file_size":2878350,"access_level":"open_access","date_created":"2019-01-21T16:12:36Z","file_name":"TNSM2846572_RIS.pdf"}]},{"language":[{"iso":"eng"}],"date_updated":"2022-01-06T07:02:50Z","oa":"1","department":[{"_id":"75"}],"project":[{"_id":"28","name":"5G Development and validation platform for global industry-specific network services and Apps","grant_number":"761493"},{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C3","_id":"15"}],"publication_status":"accepted","place":"Rome","title":"Understand your chains and keep your deadlines: Introducing time-constrained profiling for NFV","main_file_link":[{"url":"https://ieeexplore.ieee.org/abstract/document/8584974"}],"citation":{"short":"M.

In doing so, various optimization objectives are conceivable, e.g., minimizing certain required resources or the end-to-end delay of the placed services.\r\n\r\nIn this paper, we investigate the relationship between four typical optimization objectives when coordinating the placement and resource allocation of chained VNF instances. We observe an interesting trade-off between minimizing the overhead of starting/stopping VNF instances and all other objectives when adapting to changed service demands.","lang":"eng"}],"ddc":["040"],"user_id":"35343","author":[{"last_name":"Schneider","id":"35343","first_name":"Stefan Balthasar","orcid":"0000-0001-8210-4011","full_name":"Schneider, Stefan Balthasar"},{"last_name":"Dräxler","id":"31764","first_name":"Sevil","full_name":"Dräxler, Sevil"},{"last_name":"Karl","id":"126","first_name":"Holger","full_name":"Karl, Holger"}],"publisher":"IEEE","file_date_updated":"2019-01-24T13:53:16Z","publication":"IEEE Global Communications Conference (GLOBECOM 2018)","file":[{"date_updated":"2019-01-24T13:53:16Z","content_type":"application/pdf","relation":"main_file","file_size":422196,"file_id":"6971","creator":"stschn","access_level":"open_access","date_created":"2019-01-24T13:53:16Z","file_name":"preprint_ris.pdf"}],"has_accepted_license":"1","status":"public","date_created":"2019-01-24T13:53:22Z","date_updated":"2022-01-06T07:03:24Z","oa":"1","language":[{"iso":"eng"}],"title":"Trade-offs in Dynamic Resource Allocation in Network Function Virtualization","department":[{"_id":"75"}],"project":[{"grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps","_id":"28"},{"name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"_id":"16","name":"SFB 901 - Subproject C4"}]},{"_id":"6972","conference":{"location":"Verona, Italy","name":"IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN 2018)"},"year":"2018","type":"conference","citation":{"mla":"Schneider, Stefan Balthasar, et al. “A Generic Emulation Framework for Reusing and Evaluating VNF Placement Algorithms.” IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN 2018), IEEE, 2018, doi:10.1109/NFV-SDN.2018.8725795.","bibtex":"@inproceedings{Schneider_Peuster_Karl_2018, title={A Generic Emulation Framework for Reusing and Evaluating VNF Placement Algorithms}, DOI={10.1109/NFV-SDN.2018.8725795}, booktitle={IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN 2018)}, publisher={IEEE}, author={Schneider, Stefan Balthasar and Peuster, Manuel and Karl, Holger}, year={2018} }","apa":"Schneider, S.

Furthermore, existing management and\r\norchestration (MANO) platforms only offer limited support of\r\nstandardized descriptor models or package formats, limiting the\r\nre-usability of network services.\r\n\r\nTo this end, we introduce a fully integrated, open-source\r\nNFV service development kit (SDK) with multi-MANO platform\r\nsupport. Our SDK simplifies many NFV service development\r\nsteps by offering initial generation of descriptors, advanced\r\nproject management, as well as fully automated packaging and\r\nsubmission for on-boarding. To achieve multi-platform support,\r\nwe present a package format that extends ETSI’s VNF package\r\nformat.
