The objective of the research project KING is to provide a prototype of a future carrier-grade IP platform for Next Generation Networks (NGN). It was funded partly by Siemens AG and the Federal Ministry of Education and Research. Seven major research institutes were collaborating under the guidance of Siemens AG.

  • Fraunhofer-Gesellschaft, Institute for Communication Systems, Munich
  • Fraunhofer-Gesellschaft, Institute for Open Communication Systems, Berlin
  • University of Duisburg-Essen, Institute for Experimental Mathematics, Computer Network Technology Group
  • University of Karlsruhe (TH), Institute of Telematics
  • Technical University of Munich, Institute of Communication Networks
  • University of Stuttgart, Institute of Communication Networks and Computer Engineering
  • University of Würzburg, Institute of Computer Science, Department of Distributed Systems

Our contributions within this project were:

  • Classification and performance evaluation of conventional network admission control (NAC) methods
  • Design and performance evaluation of a resilient NAC that protects the network against overload due to redirected traffic in failure cases
  • Algorithms for the configuration of a resilient NAC prototype
  • Design and performance evaluation of an experience-based admission control (EBAC)
  • Design and comparison of measurement techniques for time-dependent rates
  • Design of concepts for IP-fast rerouting, e.g. multi-topology routing
  • Comparative study regarding the efficiency of NAC and capacity overprovisioning (CO)
