  text: "Signal processing in WASNs is based on a software framework for hosting the
    algorithms as well as on a set of wireless connected devices representing the
    hardware. Each of the nodes contributes memory, processing power, communication
    bandwidth and some sensor information for the tasks to be solved on the network.
    \r\nIn this paper we present our MARVELO framework for distributed signal processing.
    It is intended for transforming existing centralized implementations into distributed
    versions. To this end, the software only needs a block-oriented implementation,
    which MARVELO picks-up and distributes on the network. Additionally, our sensor
    node hardware and the audio interfaces responsible for multi-channel recordings
    are presented."

  text: The microservice architecture uses independently running microservices as
    build- ing blocks for applications. 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.

  text: Network function virtualization and software-defined networking allow services
    consisting of virtual network functions to be designed and implemented with great
    flexibility by facilitating automatic deployments, migrations, and reconfigurations
    for services and their components. 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.

  text: 'A current trend in networking and cloud computing is to provide compute resources
    at widely distributed sites; this is exemplified by developments such as Network
    Function Virtualisation. 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.'

  text: In conventional large-scale networks, creation and management of network services
    are costly and complex tasks that often consume a lot of resources, including
    time and manpower. 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.

  text: "Developing a virtualized network service does not only involve the\r\n  implementation
    and configuration of the network functions it is\r\n  composed of but also its
    integration and test with management\r\n  solutions that will control the service
    in its production\r\n  environment. These integration tasks require testbeds that
    offer the\r\n  needed network function virtualization infrastructure~(NFVI), like
    OpenStack, introducing a\r\n  lot of management and maintenance overheads. Such
    testbed setups\r\n  become even more complicated when the multi\r\n  point-of-presence~(PoP)
    case, with multiple infrastructure\r\n  installations, is considered.\r\n\r\n
    \ In this demo, we showcase an emulation platform that executes\r\n  containerized
    network services in user-defined multi-PoP\r\n  topologies. The platform does
    not only allow network service developers to\r\n  locally test their services
    but also to connect real-world\r\n  management and orchestration solutions to
    the emulated PoPs. During our\r\n  interactive demonstration we focus on the integration
    between\r\n  the emulated infrastructure and state-of-the-art orchestration\r\n
    \ solutions like SONATA or OSM."

  text: Management of complex network services requires flexible and efficient service
    provisioning as well as optimized handling of continuous changes in the workload
    of the service.To adapt to changes in the demand, service components need to be
    replicated (scaling) and allocated to physical resources (placement) dynamically.
    In this paper, we propose a fullyautomated approach to the joint optimization
    problem of scaling and placement, 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 andeffectiveness of the proposed approach.

  text: "Benchmarking and profiling virtual network functions (VNFs) generates input\r\nknowledge
    for resource management decisions taken by \r\nmanagement and orchestration systems.
    \r\nSuch VNFs are usually not executed in isolation but are often deployed as
    part of a service function chain (SFC) that connects single functions into complex
    \r\nstructures. To manage such chains, isolated performance\r\nprofiles of single
    functions have to be combined to get insights into \r\nthe overall behavior of
    an SFC. This becomes particularly\r\nchallenging in highly agile DevOps environments
    in which profiling\r\nprocesses need to be fully automated and detailed insights
    about a chain's\r\ninternal structures are not always available. \r\n\r\nIn this
    paper, we introduce a\r\nfully automatable, flexible, and platform-agnostic profiling\r\nsystem
    that allows to profile entire SFCs at once. This obviates \r\nmanual modeling
    procedures to combine profiling results from single\r\nVNFs to reflect SFC performance.
    \r\nWe use a case study with different SFC configurations to show that it\r\nis
    hard to model the resulting SFC performance based on single-VNF measurements and
    that\r\nperformance interactions between real, non-trivial functions that are
    deployed in a\r\nchain exist.  "

  text: The Service Programming and Orchestration for Virtualised Software Networks
    (SONATA) project targets both the flexible programmability of software networks
    and the optimisation of their deployments by means of integrating Development
    and Operations in order to accelerate industry adoption of software networks and
    reduce time-to-market for networked services. SONATA supports network function
    chaining and orchestration, making service platforms modular and easier to customise
    to the needs of different service providers, and introduces a specialised Development
    and Operations model for supporting developers.

  text: "Allocating resources to virtualized network functions and services to meet
    service level agreements is a challenging task for NFV management and orchestration
    systems. 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."

  text: "Traditional cellular networks are forced to remain active regardless of the
    actual amount of traffic that is currently produced/requested, with a clear waste
    of energy. Two-layer mobile networks with separated signalling and data layers
    have been recently proposed for energy savings in future implementations. These
    networks are able to switch off unneeded data cells completely while maintaining
    full coverage with their signalling cells, thus saving energy. In this demonstration,
    we showcase a testbed that uses Wi-Fi access points to emulate small cells of
    the data layer and a publicly available cellular connection as the signalling
    layer. We use off-the-shelf Android smartphones with an ad-hoc networking management
    module and a MultiPath TCP-enabled kernel to manage the Wi-Fi and cellular interfaces
    simultaneously.\r\nThe testbed is used to demonstrate the general feasibility
    of this layered architecture and to facilitate experiments with network-wide resource
    optimization. "
