  text: "In den letzten Jahren haben sich Software-Ökosysteme als neue, erfolgreiche
    Geschäftsform etabliert. Unternehmen agieren hierbei als Anbieter von Software-Plattformen,
    auf denen Drittanbieter Softwarelösungen für den Markt anbieten können.  Etablierte
    Beispiele sind hierbei sogenannte App-Stores, die z.B. von Google oder Apple angeboten
    werden.\r\n\r\nBeim Aufbau von Software-Ökosystemen müssen vom Plattformanbieter
    viele architektonische Entwurfsentscheidungen getroffen werden. Bisher gibt es
    keine Architekturrichtlinien und -werkzeuge, die den Entwurf einer Ökosystemarchitektur
    unterstützen. Dadurch fehlt hier systematisches, wiederverwendbares Wissen. Plattformanbieter
    müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im
    Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer
    Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen:
    Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt
    es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen.
    Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von
    Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen
    die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden
    diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung
    von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach:
    \r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare
    Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis
    wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus
    existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme
    konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten
    und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert
    methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und
    zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert
    wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen
    Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und
    der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie
    wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines
    Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache
    und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren
    und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation
    wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie
    wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen
    zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von
    existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des
    Frameworks durchgeführt."

  text: Network and service coordination is important to provide modern services consisting
    of multiple interconnected components, e.g., in 5G, network function virtualization
    (NFV), or cloud and edge computing. In this paper, I outline my dissertation research,
    which proposes six approaches to automate such network and service coordination.
    All approaches dynamically react to the current demand and optimize coordination
    for high service quality and low costs. The approaches range from centralized
    to distributed methods and from conventional heuristic algorithms and mixed-integer
    linear programs to machine learning approaches using supervised and reinforcement
    learning. I briefly discuss their main ideas and advantages over other state-of-the-art
    approaches and compare strengths and weaknesses.

  text: "Purpose\r\nThe purpose of this paper is to identify strategic options and
    challenges that arise when an industrial firm moves from providing smart service
    toward providing a platform.\r\n\r\nDesign/methodology/approach\r\nThis conceptual
    study takes on a multidisciplinary research perspective that integrates concepts,
    theories and insights from service management and marketing, information systems
    and platform economics.\r\n\r\nFindings\r\nThe paper outlines three platform types
    – smart data platform, smart product platform and matching platform – as strategic
    options for firms that wish to evolve from smart service providers to platform
    providers.\r\n\r\nResearch limitations/implications\r\nInvestigating smart service
    platforms calls for launching interdisciplinary research initiatives. Promising
    research avenues are outlined to span boundaries that separate different research
    disciplines today.\r\n\r\nPractical implications\r\nManaging a successful transition
    from providing smart service toward providing a platform requires making significant
    investments in IT, platform-related capabilities and skills, as well as implement
    new approaches toward relationship management and brand-building.\r\n\r\nOriginality/value\r\nThe
    findings described in this paper are valuable to researchers in multiple disciplines
    seeking to develop and to justify theory related to platforms in industrial scenarios."

abstract:
- lang: eng
  text: Mobile shopping apps have been using Augmented Reality (AR) in the last years
    to place their products in the environment of the customer. While this is possible
    with atomic 3D objects, there is is still a lack in the runtime configuration of
    3D object compositions based on user needs and environmental constraints. For
    this, we previously developed an approach for model-based AR-assisted product
    configuration based on the concept of Dynamic Software Product Lines. In this demonstration
    paper, we present the corresponding tool support ProConAR in the form of a Product
    Modeler and a Product Configurator. While the Product Modeler is an Angular web
    app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table
    legs, funnier) and saves it within a configuration model, the Product Configurator
    is an Android client that uses the configuration model to place different product
    configurations within the environment of the customer. We show technical details
    of our ready to use tool-chain ProConAR by describing its implementation and usage
    as well as pointing out future research directions.

  text: "Modern services consist of modular, interconnected\r\ncomponents, e.g., microservices
    forming a service mesh. To\r\ndynamically adjust to ever-changing service demands,
    service\r\ncomponents have to be instantiated on nodes across the network.\r\nIncoming
    flows requesting a service then need to be routed\r\nthrough the deployed instances
    while considering node and link\r\ncapacities. Ultimately, the goal is to maximize
    the successfully\r\nserved flows and Quality of Service (QoS) through online service\r\ncoordination.
    Current approaches for service coordination are\r\nusually centralized, assuming
    up-to-date global knowledge and\r\nmaking global decisions for all nodes in the
    network. Such global\r\nknowledge and centralized decisions are not realistic
    in practical\r\nlarge-scale networks.\r\n\r\nTo solve this problem, we propose
    two algorithms for fully\r\ndistributed service coordination. The proposed algorithms
    can be\r\nexecuted individually at each node in parallel and require only\r\nvery
    limited global knowledge. We compare and evaluate both\r\nalgorithms with a state-of-the-art
    centralized approach in extensive\r\nsimulations on a large-scale, real-world
    network topology.\r\nOur results indicate that the two algorithms can compete
    with\r\ncentralized approaches in terms of solution quality but require\r\nless
    global knowledge and are magnitudes faster (more than\r\n100x)."

  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: "Verifiable random functions (VRFs) are essentially digital signatures with
    additional properties, namely verifiable uniqueness and pseudorandomness, which
    make VRFs a useful tool, e.g., to prevent enumeration in DNSSEC Authenticated
    Denial of Existence and the CONIKS key management system, or in the random committee
    selection of the Algorand blockchain.\r\n\r\nMost standard-model VRFs rely on
    admissible hash functions (AHFs) to achieve security against adaptive attacks
    in the standard model. Known AHF constructions are based on error-correcting codes,
    which yield asymptotically efficient constructions. However, previous works do
    not clarify how the code should be instantiated concretely in the real world.
    The rate and the minimal distance of the selected code have significant impact
    on the efficiency of the resulting cryptosystem, therefore it is unclear if and
    how the aforementioned constructions can be used in practice.\r\n\r\nFirst, we
    explain inherent limitations of code-based AHFs. Concretely, we assume that even
    if we were given codes that achieve the well-known Gilbert-Varshamov or McEliece-Rodemich-Rumsey-Welch
    bounds, existing AHF-based constructions of verifiable random functions (VRFs)
    can only be instantiated quite inefficiently. Then we introduce and construct
    computational AHFs (cAHFs). While classical AHFs are information-theoretic, and
    therefore work even in presence of computationally unbounded adversaries, cAHFs
    provide only security against computationally bounded adversaries. However, we
    show that cAHFs can be instantiated significantly more efficiently. Finally, we
    use our cAHF to construct the currently most efficient verifiable random function
    with full adaptive security in the standard model."
