Using Networks to Teach About Networks (Dagstuhl Seminar 17112)

Authors: Timur Friedman, Aiko Pras, and Jürgen Schönwälder

Published in: Dagstuhl Reports, Volume 7, Issue 3 (2017)

Abstract
his report documents the program and the outcomes of Dagstuhl Seminar 17112 "Using Networks to Teach About Networks". The seminar brought together people with mixed backgrounds in order to exchange experiences gained with different approaches to teach computer networking. Despite the obvious question of what to teach, special attention was given to the questions of how to teach and which tools and infrastructures can be used effectively today for teaching purposes.

Learning from the Past: Implications for the Future Internet and its Management? (Dagstuhl Seminar 11042)

Authors: Gabi Dreo Rodosek, Aiko Pras, Henning Schulzrinne, and Burkhard Stiller

Published in: Dagstuhl Reports, Volume 1, Issue 1 (2011)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 11042 ``Learning from the Past: Implications for the Future Internet and its Management?''. The discussion centered around the question if by analyzing the past - especially why certain technologies did or did not succeed - it is possible to reason about the Future Internet, the challenges and especially the management aspect. Valuable observations have been identified during the discussions. A scientific publication that summarizes the key findings is under preparation.

09211 Executive Summary – Visualization and Monitoring of Network Traffic

Authors: Daniel A. Keim, Aiko Pras, Jürgen Schönwälder, Pak Chung Wong, and Florian Mansmann

Published in: Dagstuhl Seminar Proceedings, Volume 9211, Visualization and Monitoring of Network Traffic (2009)

Abstract
The seamless operation of the Internet requires being able to monitor and visualize the actual behaviour of the network. Today, IP network operators usually collect network flow statistics from critical points of their network infrastructure. Flows aggregate packets that share common properties. Flow records are stored and analyzed to extract accounting information and increasingly to identify and isolate network problems or security incidents. While network problems or attacks significantly changing traffic patterns are relatively easy to identify, it tends to be much more challenging to identify creeping changes or attacks and faults that manifest themselves only by very careful analysis of initially seemingly unrelated traffic pattern and their changes. There are currently no deployable good solutions and research in this area is just starting. In addition, the large volume of flow data on high capacity networks and exchange points requires to move to probabilistic sampling techniques, which require new analysis techniques to calculate and also visualize the uncertainty attached to data sets.

08043 Summary – Perspectives Workshop: Telecommunication Economics

Authors: Heikki Hammainen, Hong Chen, Aiko Pras, George Huitema, Martin Waldburger, David Hausheer, Panayotis Antoniadis, Peter Reichl, Jerzy Kubasik, and Burkhard Stiller

Published in: Dagstuhl Seminar Proceedings, Volume 8043, Perspectives Workshop: Telecommunication Economics (2008)

Abstract
The telecommunications sector and the Internet section of Internet Service Providers (ISP) have become a dynamic key area for the economic development of industrialized nations in the world. It is in constant evolution. Because of intense competition, telecommunications companies and ISPs are forced to diversify their offers and thus to propose an increasing number of services. However, economic analysis often ignores important technical aspects of telecommunications and is not aware of new developments. Engineering models often ignore economic factors. Thus, the design and deployment of future networks that incorporate new services are subject to uncertainties such as equipment and capacity prices (due to technological innovation), demand and supply for services (due to competition). Seeing leading researchers bringing together with various backgrounds, all working on innovative aspects of technical, techno-economic, social, and regulatory issues, lead to the following four main areas that have been – partially – tackled in an integrated manner: - Architectural side, - Social side, - Economic and business side, and - Regulatory side.
