In this presentation, I will discuss how an SDN Controller that receives streaming telemetry from the network can automatically tune the paths of SR-TE or RSVP-TE LSPs in order to avoid congestion occurring. Contrary to popular belief, it is not necessary to fully mesh all of the edge nodes with TE LSPs to achieve this. None about this event: https://pretalx.com/denog13/talk/YT9R78/

In recent years so called "research networks", owned and operated by individuals, are on the rise. These networks are using public ASNs, IPv4 and IPv6 prefixes and are participating in the DFZ. Whilst hands-on learning in general is great, we need to put this in context of the general stability of the internet at large, especially in current times, where routing security is not a default. This tal...

This presentation describes recent enhancements to PING and TRACEROUTE as per RFC 5837 and RFC 8335. It also describes recent implementations. None about this event: https://pretalx.com/denog13/talk/BCNAHM/

There are several approved best practices and well-established procedures in aviation to reduce risk and guarantee safety. If you are running an operations team, there are some takeaways to improve your daily business. None about this event: https://pretalx.com/denog13/talk/LXQERW/

BGP local-preference is one of the most powerful attributes, but naively used, it inevitably gets in the way, and creates avoidable troubles for other networks. This talk shows a few commonly used variants and the unwanted consequences. None about this event: https://pretalx.com/denog13/talk/RVC77F/

FTTH deployments and PONs (Passive Optical Networks) are coming up more often in discussions amongst network operators, and many times PON is used synonymous with inferior technology: only dark fiber is considered the one true solution. As a network engineer with a strong Service Provider background, I can relate to this viewpoint, and while it is technically correct, the real world imposes financ...

Fast DNS resolvers are a crucial component in delivering a snappy internet experience for end-customers. If the resolvers are down or under heavy load, even the best internet connection is useless for most customers. In this talk I'll cover how to design and set up a scalable, highly available DNS resolver infrastructure for internet service providers. - Anycast IPs using BGP for horizontal scalin...

Booking.com runs large parts of its infrastructure on on-premise L3 Clos networks of non-trivial sizes. This talk presents our in-house end-to-end monitoring system that checks and reports on the health of the network, and helps us in checking our SLOs, and an ad-hoc tool used to debug ECMP issues in these networks.

I identified all the IPv4 allocations by RIPE NCC to Germany, and did a programmatic survey of the state of reverse DNS for this data. I present my findings and talk very briefly about the benefits to network operators of establishing PTR records for external-facing nodes.

Tired of manually updating the ripe-db? What if the ripe-db is updated when you document your prefixes in netbox? Let's automate this on creation, update and deletion of objects. Dealing with corner cases such as overlapping prefixes is also covered. Backups included. None about this event: https://pretalx.com/denog13/talk/MFFTL7/

In this presentation we will explore how Quantum Key Distribution (QKD) works and how it can be leveraged in existing security mechanisms. Before diving into QKD we will first look at some of the quantum terminology and principles. We will also explore what a Quantum Network and/or Quantum Internet is.

BNG Blaster - https://github.com/rtbrick/bngblaster When we started to build and test our BNG software for open hardware platforms, we got increasingly frustrated with the abilities and test methodology of commercial network testing software. Most solutions come with a dedicated hardware chassis or VMs with high CPU and memory requirements. Commercial network testing software is often limited by s...

Was bedeutet der Bedarf an Rohstoffen der Industrieländer für die Regionen im Globalen Süden, in denen sie gewonnen werden? In diesem Debate spricht Johanna Sydow von der NGO Germanwatch mit uns über Arbeitsverhältnisse, gesundheitliche Auswirkungen und Umweltschäden im Kontext von Mining. Und auch darüber, was das mit uns selbst zu tun hat: vor allem im IT-Bereich ist der Bedarf an bestimmten, du...
