  text: "Modern services comprise interconnected components,\r\ne.g., microservices
    in a service mesh, that can scale and\r\nrun on multiple nodes across the network
    on demand. To process\r\nincoming traffic, service components have to be instantiated
    and\r\ntraffic assigned to these instances, taking capacities and changing\r\ndemands
    into account. This challenge is usually solved with\r\ncustom approaches designed
    by experts. While this typically\r\nworks well for the considered scenario, the
    models often rely\r\non unrealistic assumptions or on knowledge that is not available\r\nin
    practice (e.g., a priori knowledge).\r\n\r\nWe propose a novel deep reinforcement
    learning approach that\r\nlearns how to best coordinate services and is geared
    towards\r\nrealistic assumptions. It interacts with the network and relies on\r\navailable,
    possibly delayed monitoring information. Rather than\r\ndefining a complex model
    or an algorithm how to achieve an\r\nobjective, our model-free approach adapts
    to various objectives\r\nand traffic patterns. An agent is trained offline without
    expert\r\nknowledge and then applied online with minimal overhead. Compared\r\nto
    a state-of-the-art heuristic, it significantly improves flow\r\nthroughput and
    overall network utility on real-world network\r\ntopologies and traffic traces.
    It also learns to optimize different\r\nobjectives, generalizes to scenarios with
    unseen, stochastic traffic\r\npatterns, and scales to large real-world networks."

  text: Data-parallel applications run on cluster of servers in a datacenter and their
    communication triggers correlated resource demand on multiple links that can be
    abstracted as coflow. They often desire predictable network performance, which
    can be passed to network via coflow abstraction for application-aware network
    scheduling. In this paper, we propose a heuristic and an optimization algorithm
    for predictable network performance such that they guarantee coflows completion
    within their deadlines. The algorithms also ensure high network utilization, i.e.,
    it's work-conserving, and avoids starvation of coflows. We evaluate both algorithms
    via trace-driven simulation and show that they admit 1.1x more coflows than the
    Varys scheme while meeting their deadlines.

  text: "Network function virtualization (NFV) proposes\r\nto replace physical middleboxes
    with more flexible virtual\r\nnetwork functions (VNFs). To dynamically adjust
    to everchanging\r\ntraffic demands, VNFs have to be instantiated and\r\ntheir
    allocated resources have to be adjusted on demand.\r\nDeciding the amount of allocated
    resources is non-trivial.\r\nExisting optimization approaches often assume fixed
    resource\r\nrequirements for each VNF instance. However, this can easily\r\nlead
    to either waste of resources or bad service quality if too\r\nmany or too few
    resources are allocated.\r\n\r\nTo solve this problem, we train machine learning
    models\r\non real VNF data, containing measurements of performance\r\nand resource
    requirements. For each VNF, the trained models\r\ncan then accurately predict
    the required resources to handle\r\na certain traffic load. We integrate these
    machine learning\r\nmodels into an algorithm for joint VNF scaling and placement\r\nand
    evaluate their impact on resulting VNF placements. Our\r\nevaluation based on
    real-world data shows that using suitable\r\nmachine learning models effectively
    avoids over- and underallocation\r\nof resources, leading to up to 12 times lower
    resource\r\nconsumption and better service quality with up to 4.5 times\r\nlower
    total delay than using standard fixed resource allocation."

  text: Currently, the coexistence of multiple users and devices challenges the network's
    ability to reliably connect them. This article proposes a novel communication
    architecture that satisfies the requirements of fifth-generation (5G) mobile network
    applications. In particular, this architecture extends and combines ultra-dense
    networking (UDN), multi-access edge computing (MEC), and virtual infrastructure
    manager (VIM) concepts to provide a flexible network of moving radio access (RA)
    nodes, flying or moving to areas where users and devices struggle for connectivity
    and data rate. Furthermore, advances in radio communications and non-orthogonal
    multiple access (NOMA), virtualization technologies and energy-awareness mechanisms
    are integrated towards a mobile UDN that not only allows RA nodes to follow the
    user but also enables the virtualized network functions (VNFs) to adapt to user
    mobility by migrating from one node to another. Performance evaluation shows that
    the underlying network improves connectivity of users and devices through the
    flexible deployment of moving RA nodes and the use of NOMA.

  text: 'Assigning bands of the wireless spectrum as resources to users is a common
    problem in wireless networks. 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.'

  text: "Softwarization facilitates the introduction of smart\r\nmanufacturing applications
    in the industry. Manifold devices\r\nsuch as machine computers, Industrial IoT
    devices, tablets,\r\nsmartphones and smart glasses are integrated into factory
    networks\r\nto enable shop floor digitalization and big data analysis. To\r\nhandle
    the increasing number of devices and the resulting traffic,\r\na flexible and
    scalable factory network is necessary which can be\r\nrealized using softwarization
    technologies like Network Function\r\nVirtualization (NFV). However, the security
    risks increase with\r\nthe increasing number of new devices, so that cyber security
    must\r\nalso be considered in NFV-based networks.\r\n\r\nTherefore, extending
    our previous work, we showcase threat\r\ndetection using a cloud-native NFV-driven
    intrusion detection\r\nsystem (IDS) that is integrated in our industrial-specific
    network\r\nservices. As a result of the threat detection, the affected network\r\nservice
    is put into quarantine via automatic network reconfiguration.\r\nWe use the 5GTANGO
    service platform to deploy our\r\ndeveloped network services on Kubernetes and
    to initiate the\r\nnetwork reconfiguration."

  text: "For optimal placement and orchestration of network services, it is crucial\r\nthat
    their structure and semantics are specified clearly and comprehensively\r\nand
    are available to an orchestrator. Existing specification approaches are\r\neither
    ambiguous or miss important aspects regarding the behavior of virtual\r\nnetwork
    functions (VNFs) forming a service. We propose to formally and\r\nunambiguously
    specify the behavior of these functions and services using\r\nQueuing Petri Nets
    (QPNs). QPNs are an established method that allows to\r\nexpress queuing, synchronization,
    stochastically distributed processing delays,\r\nand changing traffic volume and
    characteristics at each VNF. With QPNs,\r\nmultiple VNFs can be connected to complete
    network services in any structure,\r\neven specifying bidirectional network services
    containing loops.\r\n  We discuss how management and orchestration systems can
    benefit from our\r\nclear and comprehensive specification approach, leading to
    better placement of\r\nVNFs and improved Quality of Service. Another benefit of
    formally specifying\r\nnetwork services with QPNs are diverse analysis options,
    which allow valuable\r\ninsights such as the distribution of end-to-end delay.
    We propose a tool-based\r\nworkflow that supports the specification of network
    services and the automatic\r\ngeneration of corresponding simulation code to enable
    an in-depth analysis of\r\ntheir behavior and performance."

  text: "As 5G and network function virtualization (NFV) are maturing, it becomes
    crucial to demonstrate their feasibility and benefits by means of vertical scenarios.
    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."

  text: "The ongoing softwarization of networks creates a big need for automated testing
    solutions to ensure service quality. This becomes even more important if agile
    environments with short time to market and high demands, in terms of service performance
    and availability, are considered.\r\nIn this paper, we introduce a novel testing
    solution for virtualized, microservice-based network functions and services, which
    we base on TTCN-3, a well known testing language defined by the European standards
    institute (ETSI). We use TTCN-3 not only for functional testing but also answer
    the question whether TTCN-3 can be used for  performance profiling tasks as well.
    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."

  text: "5G together with software defined networking (SDN) and network function virtualisation
    (NFV) will enable a wide variety of vertical use cases. One of them is the smart
    man- ufacturing case which utilises 5G networks to interconnect production machines,
    machine parks, and factory sites to enable new possibilities in terms of flexibility,
    automation, and novel applications (industry 4.0). However, the availability of
    realistic and practical proof-of-concepts for those smart manufacturing scenarios
    is still limited.\r\nThis demo fills this gap by not only showing a real-world
    smart manufacturing application entirely implemented using NFV concepts, but also
    a lightweight prototyping framework that simplifies the realisation of vertical
    NFV proof-of-concepts. Dur- ing the demo, we show how an NFV-based smart manufacturing
    scenario can be specified, on-boarded, and instantiated before we demonstrate
    how the presented NFV services simplify machine data collection, aggregation,
    and analysis."

  text: "Softwarized networks are the key enabler for elastic, on-demand service deployments
    of virtualized network functions. 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."

  text: By distributing the computational load over the nodes of a Wireless Acoustic
    Sensor Network (WASN), the real-time capability of the TRINICON (TRIple-N-Independent
    component analysis for CONvolutive mixtures) framework for Blind Source Separation
    (BSS) can be ensured, even if the individual network nodes are not powerful enough
    to run TRINICON in real-time by themselves. 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.

  text: Internet of Things (IoT) applications witness an exceptional evolution of
    traffic demands, while existing protocols, as seen in wireless sensor networks
    (WSNs), struggle to cope with these demands. 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.

  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.
