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.

Brief Announcement
Brief Announcement: On Self-Adjusting Skip List Networks

Authors: Chen Avin, Iosif Salem, and Stefan Schmid

Published in: LIPIcs, Volume 146, 33rd International Symposium on Distributed Computing (DISC 2019)


Abstract
This paper explores the design of dynamic network topologies which adjust to the workload they serve, in an online manner. Such self-adjusting networks (SANs) are enabled by emerging optical technologies, and can be found, e.g., in datacenters. SANs can be used to reduce routing costs by moving frequently communicating nodes topologically closer. This paper presents SANs which provide, for the first time, provable working set guarantees: the routing cost between node pairs is proportional to how recently these nodes communicated last time. Our SANs rely on skip lists (which serve as the topology) and provide additional interesting properties such as local routing.
