  text: Service Level Agreements are essential tools enabling clients and telco operators
    to specify required quality of service. The 5GTANGO NFV platform enables SLAs
    through policies and custom service lifecycle management components. This allows
    the operator to trigger certain lifecycle management events for a service, and
    the network service developer to define how to execute such events (e.g., how
    to scale). In this demo we will demonstrate this unique 5GTANGO concept using
    an elastic proxy service supported by a high availability SLA enforced through
    a range of traffic regimes.

  text: Intelligent mechatronic systems other the possibility to adapt system behavior
    to current dependability. This can be used to assure reliability by controlling
    system behavior to reach a pre-defined lifetime. By using such closed loop control,
    the margin of error of useful lifetime of an individual system is lowered. It
    is also possible to change the pre-defined lifetime during operation, by adapting
    system behavior to derate component usage. When planning maintenance actions,
    the remaining useful lifetime of each individual system has to be taken into account.
    Usually, stochastic properties of a fleet of systems are analyzed to create maintenance
    plans. Among these, the main factor is the probability of an individual system
    to last until maintenance. If condition-based maintenance is used, this is updated
    for each individual system using available information about its current state.
    By lowering the margin of error of useful lifetime, which directly corresponds
    to the time until maintenance, extended maintenance periods are made possible.
    Also using reliability-adaptive operation, a reversal of degradation driven maintenance
    planning is possible where a maintenance plan is setup not only according to system
    properties, but mainly to requirements imposed by maintenance personnel or infrastructure.
    Each system then adapts its behavior accordingly and fails according to the maintenance
    plan, making better use of maintenance personnel and system capabilities at the
    same time. In this contribution, the potential of maintenance plan driven system
    behavior adaptation is shown. A model including adaptation process and maintenance
    actions is simulated over full system lifetime to assess the advantages gained.

  text: Recent advances in information processing enable new kinds of technical systems,
    called self-optimizing systems. These systems are able to adapt their objectives
    and their behavior according to the current situation and influences autonomously.
    This behavior adaptation is non-deterministic and hence self-optimization is a
    risk to the system, e.g. if the result of the self-optimization process does not
    match the suddenly changed situation. In contrary, self-optimization could be
    used to increase the dependability by pursuing objectives like reliability and
    availability. In our preceding publications we introduced the so called multi-level
    dependability concept to cope with this new kind of systems (cf. [6]). This concept
    comprises the monitoring of the system behavior, the classification of the current
    situation, and the selection of the appropriate measure, if reliability limits
    are exceeded. In this paper we present for the first time experimental results.
    The dependability concept is implemented in the self-optimizing active guidance
    system of a railway vehicle. The test drives illustrate clearly that the proposed
    concept is able to cope with, e.g., sensor failures, and is able to increase the
    reliability and availability of the active guidance module.
