Winner of the Dissertation Award of the Anton-und-Klara-Röser-Stiftung

For his PhD dissertation on “Discrete-Time Performance Analysis of Cell Multiplexers with Limited Waiting Room” Dr.-Ing. Klaus-Dieter Langer has received the Anton-und-Klara-Röser-Stiftung’s award for dissertations of outstanding merit.

Cell multiplexers are one of the key elements of packet-oriented information and communication technology. The dissertation analyses the performance behavior of such operating systems at discrete time points on the cell transport level with consideration of finite waiting space capacity. It pays particular attention both to core buffer architectures with multiple access points to a common queue and to the classical polling system with single queues at each access point.

Dr.-Ing. Klaus-Dieter Langer’s work is of decisive importance for the planning and dimensioning of single server queuing-loss systems, for instance for the choice of architecture in terms of trade-offs between buffer bandwidth and capacity, and for realization of the operating strategy. Its results are also important for providing quality of service in communication networks, and for technical control applications as well as serving as a valuable basis for further research.
