Towards More Flexible and Automated Communication Networks (Dagstuhl Seminar 22471)

Authors: Artur Hecker, Stefan Schmid, Henning Schulzrinne, Lily Hügerich, Sándor Laki, and Iosif Salem

Published in: Dagstuhl Reports, Volume 12, Issue 11 (2023)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 22471 "Towards More Flexible and Automated Communication Networks". Communication network are becoming more and more automated, allowing to overcome human configuration errors (a frequent reason for outages) and enabling a more fine-grained control, potentially improving also efficiency. For example, the percentage of employees of Telecom companies "really touching the network" is decreasing. The goal of this seminar was to bring together experts in the field to identify and discuss the key challenges in making communication networks more autonomous. To this end, the seminar was structured around a small number of enlightning keynote talks, leaving significant time for breakout sessions and discussions, as well as socializing.

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.

DotSlash - Creating Content Distribution Networks on Demand

Authors: Weibin Zhao and Henning Schulzrinne

Published in: Dagstuhl Seminar Proceedings, Volume 4411, Service Management and Self-Organization in IP-based Networks (2005)

Abstract
Traditional content distribution networks, such as Akamai, are well-suited for static web services that routinely experience large traffic volumes. They are unsuited for active content, i.e., content generated by scripts from databases, and web sites that are unlikely to receive significant number of requests. However, a few such sites will invariably experience their "fifteen minutes of fame", typically by being mentioned on a high-volume news site such as SlashDot or CNN. Such flashcrowds or "slashdot effect" will routinely cause single-server websites to collapse. We have designed and prototyped an autonomic web replication system, called DotSlash, that drafts rescue servers fully automatically, without user intervention. The system discovers suitable rescue servers via wide-area service location, either among peer servers or from a dedicated pool of rescue servers, allocates them for temporary use and redirects requests to them. The system is completely transparent to clients and does not require URL rewriting or other client modifications. We have designed two versions. The first, an Apache extension, deals only with static content, e.g., HTML pages or media objects. The second version can also replicate and execute scripts remotely. We have prototyped the system for the common LAMP (Linux, Apache, MySQL and PHP) configuration and shown that a common benchmark for bulletin boards can be replicated without code changes, yielding capacity increases bounded only by the database server. Since many such systems, including most blogs, are bottlenecked by the web server, our system can significantly increase capacity and works even for extremely rapid load increases. We are currently investigating how such systems can be further extended by increasing the database capacity of read-mostly systems with loose consistency constraints.
