This Innovation Field’s strategy is to develop solutions for converged networks that enable seamless and access-neutral broadband communication across the globe, with best quality and optimized cost efficiency.
To achieve this, fully ICT converged network technology and architecture are being developed. For the Gigabit society, seamless broadband communication solutions will be provided at home, at work and on the move.
The enabling of flexible network services is a prerequisite of a future-proof Deutsche Telekom product portfolio. Of equal importance is to support Deutsche Telekom group regarding cost efficient infrastructure rollout and sustainable operation of the existing network. Dr. Andreas Gladisch is in charge of this innovation field.
Topics include of this innovation field include Network architecture, wired- and wireless-access technologies, transport- and optical-transport technologies, high capacity switching and routing, network control functions and Quality of Service. Its goal is to develop new solutions for the operation and evolution of one network with a focus on seamless services.
The quality of multimedia services depends on all kinds of factors. The objective of the Assessment of IP-based Applications department is to research and make measurable the quality of IP-based multimedia services as perceived by the user.
This research deals with questions about the transfer of multimedia data as well as features of applications used from the user’s perspective. Particular emphasis is placed on the possibilities that converging, IP-based networks offer for innovative multimedia services. The research is therefore of a holistic nature and encompasses all levels of communication.
User-centric investigations
The department is headed by Prof. Dr. Alexander Raake. “Valid quality assessments can only be made by the user in the actual usage situation, since there is no ‘one quality’,” he explains. The subjective quality impression must be made accessible from the outside using appropriate assessment or other measurement methods. Instrumental methods for predicting quality serve to complement these complex procedures efficiently. The focus of the research is on voice, audio and video applications.
