The usage of the Service Oriented Architecture (SOA) paradigm currently changes the view on many enterprise applications. SOA allows the creation of modular and clearly defined software archi-tectures that ensure a high grade of interoperability and reusability. As even small, resource-constraint networked devices get more and more powerful it is common(More)
An experimental study shows the feasibility of service-oriented architectures for industrial automation and control systems even with respect to lower, real-time dependent control functions. For that purpose, general SOA-guidelines were refined in order to cover the distribution of control functions between services and the lay-out and management of(More)
The automatic integration of devices into dynamic, automatically configured networks alone does not take advantage of the entire potential of service oriented architectures (SOA). Using service management, independent services can be directed to perform meta tasks in a SOA network. In this paper we describe and evaluate the service management tool MOBASEC,(More)
Since many security incidents of networked computing infrastructures arise from inadequate technical management actions, we aim at a method supporting the formal analysis of those implications which administration activities may have towards system security. We apply the specification language cTLA which supports the modular description of process systems(More)
The management of distributed service systems is a complex task as changes in the system and the environment may induce reconfiguration tasks to be handled. In this paper , we deal with the automated reconfiguration of service-oriented, embedded systems. Depending on the environment such a system encounters, some of the services may need to be reconfigured(More)
Service-orientation supports the construction of flexible and comprehensive industrial applications. The growing scale and complexity of the applications, however, demand for enhanced self-management functions providing efficient self-adaptation and repair mechanisms. We propose the approach of policy-controlled self-management which has been developed and(More)
— The paradigm of Service Oriented Architectures spreads throughout the domain of business software and enterprise networks. With the proposal of the Device Profile for Web-Services also small, less powerful embedded devices should be able to interact with services of the network infrastructure they are connected to. New challenges arise when it comes to(More)
