Thanks to sponsors and volunteers, etc.

Daniel Wagner presents about most recent research activity at DE-CIX. Being part of the "Q-net-Q" consortium, latest advancements in the area of Quantum Key Distribution (QKD) in the context of data centers and at IXPs is being dicsussed. Having a slight touch of marketing style slides, the great cons and even potential show stoppers aren't dismissed; they are presented in a neutral and rational fashion to fuel an honest discussion.

An analysis of what effects were visible using RIPE Atlas anchors in the region and elsewhere.

This presentation investigates the proximity to a low Signal-to-Noise Ratio (SNR) threshold that can still maintain a tolerable Bit Error Rate (BER) in 100G / 400G / 800G network links. Additionally, we account for factors such as temperature and cable length to predict the duration for which a reliable network connection can be sustained between transceivers. The analysis, based on data retrieved using a Flexbox, focuses on comparing the reliability of coherent (16QAM) and non-coherent (PAM4) transceivers, with a detailed discussion on the implications of these technologies on network performance.

This presentation will give a practical showcase how peering related configurations can be automated using PeeringDB as a source of information. Elisa has been running automated peering configurations on their public IX sessions already for some time, so practical real-life examples will be given.

By thinking of networking concepts—such as devices, cables, and configurations—as services, we’ve achieved higher levels of abstraction. Daily operations become faster and easier when performed at this abstract level. Services are carefully modeled, hiding complex details under the hood. This transforms each abstracted service into a ‘Lego block’—simple to understand and effortlessly connect with others. The result? A ‘design once, use repeatedly’ approach that boosts efficiency and scalability.
