His presentation title is “Intent-Based Networking: Another Round of Hype?”
Remember Software Defined Networking (SDN)? It’s so last year – the industry has moved on to intent-based networking… which is often nothing more than another pile of hype.

The presentation will answer these questions:
  • Does “intent-based networking” mean anything?
  • Does it do more than manage device configurations?
  • Why is it so important to have feedback loops and post-change validation?
We’ll also touch on unicorns like machine-learning-driven intent and automated remediation, and try to figure out what could go wrong in an intent-based orchestration system.

Markus Legner, Anapaya Systems (CH)

Markus Legner is a postdoctoral researcher in the Network Security Group headed by Prof. Dr. Adrian Perrig at ETH Zurich, Switzerland. There he is working on  SCION, a next-generation path-aware Internet architecture that at the same time provides high security and high availability. In particular, he focuses on improving the control-plane security and investigating effects of end-host-based path selection on network properties.
Before joining the Network Security Group, Markus received his Ph.D. in theoretical physics from ETH Zurich in 2016.

His presentation title is “SCION: A secure Internet Architecture”. SCION is a next-generation secure Internet architecture that aims to replace BGP as the glue that connects all networks on the Internet. Built from the ground-up with security in mind, I will show how SCION addresses the main weaknesses of BGP with respect to security and availability. Furthermore, I will explain how SCION’s path architecture enables completely new type of properties and possibilities that are impossible to achieve with current technologies.

Peter Stevens, Mythic Beasts (UK)

Pete Stevens has led Mythic Beasts to be one of the first general purpose hosting providers to offer full IPv6 support and IPv6 only hosting with paying IPv6 only customer networks now in their fifth year of operation. When not being a network or linux admin he also runs quite fast, plays the piano quite well, sings badly and likes drinking beer but not necessarily in that order. He used to read physics at Cambridge University, now he reads physics to his toddler son.
His presentation title is “IPv6-only hosting”
Mythic Beasts offer IPv6 only hosting services including a Raspberry Pi cloud that does not and will never support IPv4. Whilst ‘No customer demand for IPv6’ is regularly taken as an article of faith by other providers, this talk looks at how IPv6 only hosting services are provisioned for many hundreds of customers and why avoiding IPv4 really does make your life better.

His presentation title is “WiFi DesignPro – Power vs Sensitivity and EM wave propagation complexity”
Nowadays, with the implication of WiFi connectivity and the growing number of connected devices, planning freedom is tightened with the help of professional software tools that fail to anticipate all the disturbing WiFi wireless network environment parameters. Presentation will emphasize issues of transmitting / receiving characteristics of WiFi access points in the “friendly” and “hostile” environments of the EM Wave propagation, and consequently the awareness of the importance of the baseline requirements for the design and deployment of wireless WiFi points in complex environments.

Existing WiFi networks can be improved with new admissions and their usability is extended. Additional skills rae required from the planner and the practitioner. With clear requirements and desires, a modern wireless network predicts useful coverage and number of users as a challenge. In the short presentation, problems will be presented.
