MDA - Mission


The project will consider selected items of the mathematical analysis and design of future generation Internet (FGI) which constitutes an important topic of current IST-FP7 information and communications technologies, see, e.g., NoE “EuroNF - Anticipating the Network of the Future - From Theory to Design”.

The impetuous development of new multimedia and Web services and the transfer of their related objects and message streams with different quality-of-service requirements by future generation networks (FGNs) causes a strong demand for timely and efficient processing of the requests by web and application servers as well as the efficient transport of the generated packetized flows by a high-speed network and its switching nodes. The latter are organized by new principles of rapidly evolving virtualization techniques to isolate task and flow processing at server and switching nodes in the network.

In FGNs these virtualization concepts are used at different layers of the protocol stack:


  1. services and the task processing of their involved classes will be isolated at the application layer by server virtualization to prepare the effective transport of retrieved objects subject to the QoE requirements of customers
  2. flow processing of the resulting traffic streams will be isolated at the transport layer by router virtualization techniques that are currently developed by several FGN projects.


The solution of cross-layer analysis problems arising in the context of such a virtualized infrastructure requires adequate mathematical modeling and analysis techniques to design effective processing mechanisms at these layers.
It is the main object


  • to derive basic teletraffic models of virtualized FGNs and
  • to develop efficient analysis techniques employing a queueing theorectical framework.
