This paper describes a new version of the DEN-ng context model, and how this model in conjunction with the DEN-ng policy model can be used for more effective and flexible context management. Both are part of the FOCALE autonomic network architecture. Context selects policies, which select roles that can be used, which in turn define allowed functionality(More)
In the Future Internet, free exchange of information between enterprise applications and networking systems promotes the personalization of services and enables many different types of end-user applications and management operations optimizing the network performance. As result of this free information exchange, we need to facilitate the federation of(More)
In the last two years a variety of concepts for service integration and corresponding systems have gained momentum. On the one hand, they aim for the interworking and integration of classical telecommunications and data communications services, such as telephony, voicemail, fax, e-mail, paging, etc. On the other hand, they are fo-cusing on universal service(More)
In the last years, a variety of concepts for service integration and corresponding systems have gained momentum. On the one hand, they aim for the interworking and integration of classical telecommunications and data communications services. On the other hand, they are focusing on universal service access from a variety of end user systems. Many of the(More)
The continued movement towards converged networks changes the focus to building application services that enable customers to move between different types of service providers based on their needs. Policy management becomes paramount for the rapid deployment and management of these application services. This paper presents the concept of a policy continuum(More)
Environment-aware Applications and Mobile Communications have proven significant relevance for future telecommunications and computing. This poster describes an approach to integrate heterogeneous off-the-shelf technology to fulfill the demands of environment aware applications. The integration has been done employing a CORBA based middleware. That gave us(More)
Today, previously separated networks converge. Tomorrow, this process is going to challenge the established design principles of service frameworks. The new challenges for management frameworks are approaches that address composition, scalability, reliability and robustness as well as autonomous self-adaptation of services and resources. Research in these(More)
