--- _id: '12882' abstract: - lang: eng text: One of the major challenges in implementing wireless virtualization is the resource discovery. This is particularly important for the embedding-algorithms that are used to distribute the tasks to nodes. MARVELO is a prototype framework for executing different distributed algorithms on the top of a wireless (802.11) ad-hoc network. 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. Additionally, we explain the work-flow, composition and execution of the framework. 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 - first_name: Sebastian full_name: Eikenberg, Sebastian last_name: Eikenberg - first_name: Arnold full_name: Mueller, Arnold last_name: Mueller - first_name: Lars full_name: Gansel, Lars last_name: Gansel - first_name: Alexander full_name: Makejkin, Alexander last_name: Makejkin - first_name: Kai full_name: Hannemann, Kai last_name: Hannemann - first_name: Rafael full_name: Schellenberg, Rafael last_name: Schellenberg citation: ama: 'Afifi H, Karl H, Eikenberg S, et al.

These approaches depend not only on their program code to operate properly, but also require enough input data to train their internal models. However, such training data is barely available for the software networking domain and most presented solutions rely on their own, sometimes not even published, data sets. This makes it hard, or even infeasible, to reproduce and compare many of the existing solutions. As a result, it ultimately slows down the adoption of machine learning approaches in softwarised networks. To this end, we introduce the \"softwarised network data zoo\" (SNDZoo), an open collection of software networking data sets aiming to streamline and ease machine learning research in the software networking domain. We present a general methodology to collect, archive, and publish those data sets for use by other researches and, as an example, eight initial data sets, focusing on the performance of virtualised network functions.\r\n" author: - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Peuster M, Schneider SB, Karl H.

It becomes even harder if heterogeneous services, making use of different offloading and network virtualization technologies, should be developed.\r\nIn this paper, we introduce FOP4 (Function Offloading Pro- totyping with P4), a novel prototyping platform that allows to prototype heterogeneous software network scenarios, including container-based, P4-switch-based, and SmartNIC-based network functions. The presented work substantially extends our existing Containernet platform with the means to prototype offloading scenarios. Besides presenting the platform’s system design, we evaluate its scalability and show that it can run scenarios with more than 64 P4 switch or SmartNIC nodes on a single laptop. Finally, we presented a case study in which we use the presented platform to prototype an extended in-band network telemetry use case." author: - first_name: Daniele full_name: Moro, Daniele last_name: Moro - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl - first_name: Antonio full_name: Capone, Antonio last_name: Capone citation: ama: 'Moro D, Peuster M, Karl H, Capone A.

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. Our algorithm is shown to significantly outperform these algorithms for many example scenario" article_number: '108759' author: - first_name: Alex S. full_name: Leong, Alex S. last_name: Leong - first_name: Arunselvan full_name: Ramaswamy, Arunselvan id: '66937' last_name: Ramaswamy orcid: https://orcid.org/ 0000-0001-7547-8111 - first_name: Daniel E. full_name: Quevedo, Daniel E. last_name: Quevedo - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl - first_name: Ling full_name: Shi, Ling last_name: Shi citation: ama: Leong AS, Ramaswamy A, Quevedo DE, Karl H, Shi L.

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. author: - first_name: Haitham full_name: Afifi, Haitham id: '65718' last_name: Afifi - first_name: Konrad full_name: Horbach, Konrad last_name: Horbach - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Afifi H, Horbach K, Karl H.

For this purpose and for practical research in network function virtualization in general, there is a great need for benchmarks and experimental data. 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. The data gathered from our experiments is publicly available. author: - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Marvin full_name: Illian, Marvin last_name: Illian - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Dräxler S, Peuster M, Illian M, Karl H.

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. author: - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Dräxler S, Schneider SB, Karl H.

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." 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.

They will manage resources of hundreds or even thousands of NFV infrastructure installations, so called points of presence~(PoP). Such scenarios need to be automatically tested during the development phase of a MANO system. This task becomes very challenging because large-scale NFV testbeds are hard to maintain, too expensive, or simply not available.\r\n\r\nIn this paper, we present a multi-PoP NFV infrastructure emulation platform that enables automated, large-scale testing of MANO stacks. We show that our platform can easily emulate hundreds of PoPs on a single physical machine and reduces the setup time of a test PoP by a factor of 232x compared to a DevStack-based test PoP installation. Further, we present a case study in which we test ETSI's Open Source MANO~(OSM) against our proposed system to gain insights about OSM's behaviour in large-scale NFV deployments." author: - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Michael full_name: Marchetti, Michael last_name: Marchetti - first_name: Gerado full_name: Garcia de Blas, Gerado last_name: Garcia de Blas - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Peuster M, Marchetti M, Garcia de Blas G, Karl H.

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 author: - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl - first_name: Zoltan Adam full_name: Mann, Zoltan Adam last_name: Mann citation: ama: 'Dräxler S, Karl H, Mann ZA.

These microservices are clearly bounded for each other and expose their functionality through, for instance, RESTful application inter- faces. Particularly the clear boundaries between microservices enable the reuse of microservice throughout different projects. Because of the increasing use of microservices, the composition of multiple microservices in service composition becomes a more important task. A challenging area in developing service compo- sitions is that it involves two distinct layers with few junctions. On the one hand, describes a service composition a business process, which involves multiple com- ponents. On the other hand, involves the implementation of a service composition topics like service discovery and message exchange protocols since the microser- vices involved in a service composition are located within a network environment. In this Bachelor’s Thesis, I describe a descriptions language to abstractly describe the business logic of a service composition. Furthermore, I describe a genera- tion process, which compiles this abstract description to a working microservice realizing the specified service composition. In addition to that, I provide an im- plementation of the generation process, as a proof of concept, and test it within a Kubernetes-based cluster environment. author: - first_name: Andreas full_name: Schürmann, Andreas last_name: Schürmann citation: ama: Schürmann A.

For extended flexibility, we go beyond seeing services as a fixed chain of functions. We define the service structure in a flexible way that enables changing the order of functions in case the functionality of the service is not influenced by this, and propose a YANG data model for expressing this flexibility. Flexible structures allow the network orchestration system to choose the optimal composition of service components that for example gives the best results for placement of services in the network. When number of flexible services and number of components in each service increase, combinatorial explosion limits the practical use of this flexibility. In this paper, we describe a selection heuristic that gives a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different optimization objectives. Moreover, we present a heuristic algorithm for placement of a combination of services, which aims at placing service components along shortest paths that have enough capacity for accommodating the services. By applying these solutions, we show that allowing flexibility in the service structure is feasible. author: - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: Dräxler S, Karl H.

This paves the way for wide-area service deployments with improved service quality: e.g. user-perceived response times can be reduced by offering services at nearby sites. But always assigning users to the nearest site can be a bad decision if this site is already highly utilised. This paper formalises two related decisions of allocating compute resources at different sites and assigning users to them with the goal of minimising the response times while the total number of resources to be allocated is limited – a non-linear capacitated Facility Location Problem with integrated queuing systems. To efficiently handle its non-linearity, we introduce five linear problem linearisations and adapt the currently best heuristic for a similar scenario to our scenario. All six approaches are compared in experiments for solution quality and solving time. Surprisingly, our best optimisation formulation outperforms the heuristic in both time and quality. Additionally, we evaluate the influence of distributions of available compute resources in the network on the response time: The time was halved for some configurations. The presented formulation techniques for our problem linearisations are applicable to a broader optimisation domain.' author: - first_name: Matthias full_name: Keller, Matthias last_name: Keller - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Keller M, Karl H.

Network softwarization and network function virtualization have been introduced to tackle these problems, aiming at decreasing costs and complexity of implementing new services, maintaining the implemented services, and managing available resources in service provisioning platforms and underlying infrastructures. To experience the full potential of these approaches, innovative development support tools and service provisioning environments are needed. To answer these needs, we introduce the architecture of the open-source SONATA system, a service programming, orchestration, and management framework. We present a development toolchain for virtualized network services, fully integrated with a service platform and orchestration system. We introduce the modular and flexible architecture of our system and discuss its main components and features, such as function- and service-specific managers that allow fine-grained service management, slicing support to facilitate multi-tenancy, recursiveness for improved scalability, and full-featured DevOps support. author: - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Hadi full_name: Razzaghi Kouchaksaraei, Hadi id: '60845' last_name: Razzaghi Kouchaksaraei - first_name: Michael full_name: Bredel, Michael last_name: Bredel - first_name: Johannes full_name: Lessmann, Johannes last_name: Lessmann - first_name: Thomas full_name: Soenen, Thomas last_name: Soenen - first_name: Wouter full_name: Tavernier, Wouter last_name: Tavernier - first_name: Sharon full_name: Mendel-Brin, Sharon last_name: Mendel-Brin - first_name: George full_name: Xilouris, George last_name: Xilouris citation: ama: 'Dräxler S, Karl H, Peuster M, et al.

We formalize the problem, analyze its complexity, and develop two algorithms to solve it.

This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. \r\nOne solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services.\r\n\r\nIn this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure." author: - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Peuster M, Karl H.
