AI workloads in large DC fabrics have seen its fair share of networking challanges. What are the pitfall seen, and how to address them ? With the market reacting to the expensive investments and looking for alternatives, can these solutions be distributed or moved outside DC ? Or atleast what parts ?

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...

To get the approval of your company's management or other designated decision-maker, it can be helpful to show how your proposal works towards company goals. But what if the decision-maker has incentives that don't line up with the company goals, or what if the company goals are wrong?
You and your fellow workers can address this issue by recognizing that you too are decision-makers. I will...

Dr Signe Sophus Lai (Digital Infrastructure Think Tank), Dr Sofie Flensburg (Digital Infrastructure Think Tank)3/6/25, 2:15 PMDKNOG Main TrackFull talk (up to 30 minutes)
This talk discusses the conditions and capacities for carrying out studies of the political economy of the internet using publicly available data repositories – often developed for the market rather than research purposes. Building a comparative ownership analysis of internet infrastructures in the largest Nordic welfare states, we present methodological possibilities and limitations, as well...

This presentation discusses blackhole detection in packet networks. Such blackholes are typically difficult to detect, and even working out on which router the blackhole is occurring can be difficult. We discuss two methods for detecting blackholes: indirect detection and direct detection. We describe a method for a router to report packet drops due to blackholes via IPFIX, including the...

In the late 19th century, two industrial titans were born within a few months of each other but an ocean apart. Both of these men, Henry Royce and Henry Ford, were obsessed with precision engineering and, fortunately for many of us, cars. They focused on building the best motor cars possible, though they achieved their goals in very different ways: Royce was driven by perfection, Ford by...

What does automating brown field network have to do with interior design?
A whole lot, actually!
This presentation will explain one of the most challenging problem with network automation with easy to understand examples.
The problem is universal, regardless of which automation platform you have chosen to use, and even though the author uses Cisco NSO, the presentation will be useful...

RouteViews was initiated in 1995 at the University of Oregon to allow network operators see what their routing tables looked like from an external perspective. Over the years since, this community project has set up collectors in strategic locations around the world, allowing network operators a rich view of their routing announcements, and researchers a valuable resource for tracking the...

RFC5549/RFC8950 specifies a way of announcing IPv4 routes using IPv6 next-hops, allowing networks and IXPs to remove IPv4 link addressing. There is a working group at Euro-IX that aims to test interoperability of RFC8950 implementations and lay out the basics of its usage in an IXP environment. There are also a handful of IXPs already testing RFC8950 route servers.

The current RPKI framework using ROAs only works to validate route origination.
IP Transit providers will implement filters governing which routes can be propagated based on information from the IRRs (Internet Routing Registries) - in our region the RIPE DB.This is a real life example of manipulation to the RIPE DB, which could have enabled a BGP Hijack to bypass transit provider...

It can be hard to control how your traffic will egress your AS, when you have multiple peering points. That being your internet peerings and upstream providers or Caches from Netflix and the likes. With EPE you can start getting complete control of those traffic flows. You decide what traffic to deliver to whom from where in your network.

The purpose of this talk is to go over traceroute in context of the following:
- The evolution of networks over the last few decades and how it affects traceroute
- The different algorithms in use (ie: classic, dublin, paris)
- What our expectations are from traceroute

Most admins spend their working life trying to keep malware, hackers, and their tools outside of their network. However, for the last four and a bit years, I've been working with the opposite problem. Running a network for a penetration testing company. Where the pentesters are using all the tools we'd normally like to keep a long way away from our network.
From threatmodelling, to...

PeeringDB is a freely available, user-maintained, database of networks, and the go-to location for interconnection data. The database facilitates the global interconnection of networks at Internet Exchange Points (IXPs), data centers, and other interconnection facilities, and is the first stop in making interconnection decisions.
We present regular updates at Internet related events to...

With a few simple changes, IP-transit customers can increase the reliability of the prefix filtering provided to them by their IP-transit providers, and hopefully avoid easy-to-mitigate prefix filtering issues.
As an IP-Transit provider, we (Inter.link) often encounter prefix list generation issues with our customer's IRR data. In this talk we'll present some easy to implement changes, in...
