Motivation

In the history specific networks have featured specific service architectures. With the emergence of new network technologies the need for unified Service Delivery Platforms (SDPs) raised in order to provide value-added services seamlessly on top of these networks. In addition, reusable service building blocks have been invented to speed up service creation and delivery. In the nineties Intelligent Networks (INs) have been considered as the most important telecom SDP, which have been standardized by ITU and ETSI for fixed and mobile networks. In view of the convergence of telecommunications, Internet, IT and entertainment and the resulting more complex value chains, SDPs for the provision of converged multimedia services have become quite complex. Today there is no single SDP standardization body anymore. Whereas in the telecommunications domain the IP Multimedia System (IMS) has become the defacto standard for advanced service provision in a centralized way, in the internet proprietary over the top architectures and Peer-to-Peer (P2P) architectures promote a more distributed way of service provision. In addition the notion of Service Oriented Architectures (SOA) and open Application Programming Interfaces (APIs) in the network and on the end systems  pave the way for distributed  Service Delivery Platforms. IT and internet technologies represent today the foundation for programming services and implementing service platforms. Telco operator service provisioning is still targeting at highest reliability and availability, which is sometime in contrast to the fast beta service rollout in the Internet. New mechanisms for performance evaluation and guarantee are needed to bridge both paradigms.

In view of the new ecosystems and the “long tail” vision of services, SDPs play an important strategic role for the economy. There was a big IN research community in Germany in the nineties. Today the SDP research field seems to be fragmented and not coordinated. This discussion group aims to establish again a scientific SDP community in Germany.

Target

• To create a scientific community in Germany and surrounding countries in the above field to discuss technical challenges and developments
• To create a forum for Master, Diploma and PhD students
• To bridge the gap between academia and industry

• To organize 2-3 work group meetings per year at different locations
