Talk 1: From manual to machine: The automation revolution in internet peering.

Inspired by this, this talk shall cover an open-source implementation to enable widespread adoption

Talk 1: Fifty ways not to do it, the history of how optical fibre communications were invented.

In 2009 the Nobel Prize committee gave the Physics prize to Charles Kao for the invention of fibre optical communications. But the story wasn’t that simple, and it didn’t have a single lone inventor. So how did we invent the idea of using glass fibres for long distance communications? And why are we returning to some of the discarded ideas?

Talk 1: Reconsidering the RPKI Trust Model and Validation Algorithm

In this talk Job Snijders from Fastly will explain how to reason about
‘trust’ in context of the RPKI, how the current validation algorithm
works, what the downsides of its rigidity are, and share perspective on
different, more robust approaches. Or, phrased in a more exciting way:
how to prepare for the theft of an RIR’s HSM?!?!

Presenter: Job Snijders (Fastly)


Talk 2: “Reclaiming” 240.0.0.0/4

In IPv4 class E space is magical, in that whenever anybody looks at it seems to have a fantastic opinion on how to reclaim it, This is becoming even more tempting in the era where IPv4 is hard to obtain and IPv6 deployment is frustratingly stubborn. In this talk I will go over the challenges and why it is probably not a good idea to try and use this dormant IPv4 space.

Talk 2: Fabrics

A software engineer’s view into how contemporary hardware operates and what does that mean for network and infrastructure layers, as seen in the context of machine learning hype. Fabrics, in particular non-IP fabrics, routing of address space (no, not IP address space, the real address space), Infiniband and custom transports, feeding accelerators with data and what does that mean for the networking part of the system, and how software could and does abuse the potential of underlying hardware.
