Design‑driven automation treats the high-level design of infrastructure as a first‑class artifact: an explicit model of topology, roles, relationships, and constraints that exists independently of any particular device configuration.
In this talk, we will explore what design‑driven automation means in practice, why it emerged, and why it keeps resurfacing whenever networks reach a certain...
Network Automation has been around long enough that it progressed through different stages. In the early days network engineers were happy that we could write templates, merge them with variables and push the result out to the devices.
By now, we can see that we need a place where to store those variables in a sensible way, through documentation systems (or DCIMs). But with this we enter a...
Recent geopolitical tensions have placed digital sovereignty as a key buzzword in public and political debates, emphasising the dominance of US-based tech corporations across the digital market. In Denmark, the Minister of Digitalisation has taken several measures to ‘liberate’ the public sector from infrastructural dependencies and the economic consequences they entail. Meanwhile,...
Greenland’s digital ecosystem is characterised by structural dependence on U.S.-controlled infrastructure across multiple layers: limited international backbone connectivity via a small 2 submarine cables and limited satellite links, routing and traffic flows largely terminating outside Greenland.
This talk examines how constrained path diversity, external routing and hosting, minimal local...
We have an issue in the network industry - we're stuck in the ways we think and the ways we work.
Why change something just to change it? Well, why not? This lightning talk aims to challenge our industry's resistance to change and provides food for thought on breaking free from outdated practices.
This talk is a short, practical story about a network engineer who wanted repeatable ECMP troubleshooting and also wanted to learn a new programming language. Starting from familiar tools (traceroute, Wireshark, RFCs), I built a small ECMP‑aware probing tool and translated manual workflows into code.
The focus is less on the tool itself and more on the method: start in a domain you trust,...
In the old days of traditional separation of IP and DWDM, there was no need for IP folks to care about much other than what they used on their routers/switches (while the transport team ran the DWDM infra). These past DWDM infra approaches for maximizing the data capacity per fiber pair went for running more and more DWDM channels with grid spacings as small as possible. This meant that grid...
What happens when a language teacher is dropped into the deep end of the telecom industry, with zero background in fiber, DWDM, or why “it depends” is the only honest answer to anything? This talk is a personal journey of switching careers from academia and language teaching into the world of tech sales in a fast-moving, acronym-rich, and precision-driven industry.
The presentation will...
In high-performance optical communication systems transceiver health and efficiency are critical to network reliability and energy consumption. This presentation explores the powerful capabilities of Versatile Diagnostics Monitoring (VDM) features found in modern optical transceivers (beyond the speed of 100G) with a particular focus on the Thermoelectric Cooler (TEC) current metrics. By...
This presentation is showing and discussing observations of what trends and changes can be seen after the cable cuts near the shore of Yemen in September. We try to highlight findings and interesting changes in routing or traffic shifts.
The findings are valid globally and not just Middle East related. It serves as a great example of do's and don'ts in your routing-setup.
In the past it was believed that network operators should periodically download clear text data from the Internet and put them into the configuration of their routers to make routing more secure.
RPKI is a technology to secure routing which employs proper cryptography. For years we have used it for Route Origin Authorization. New feature of routing security is being deployed now: Autonomous...
The presentation covers a prototype of my auto-bandwidth solution for Segment Routing Traffic Engineering.
The solution is open standard and multi-vendor (existing bandwidth-aware SR-TE solutions are vendor specific).
The prototype also includes an open source tool SR-TE bandwidth sampler, which collects SR policy counters via GNMI, calculates traffic rate and converts it into the BGP-LS...
As the service provider market slowly consolidates, network engineers and architects will increasingly face the complex challenge of merging service provider networks. This technical talk dives into the intricacies of integrating distinct IP/MPLS network infrastructures, focusing on practical considerations and potential pitfalls. Based on past experience, we will discuss the general approach...
Route servers are the most important service (other than moving packets itself) on an internet exchange fabric, however in most exchanges peering with them is not mandatory.
This talk aims to answer the question of how effective route servers are and distributing routes to many networks, using the large internet exchange deployment footprint of the bgp.tools route collector network, we will...
“Automate what makes sense” sounds practical. In many network orgs, it becomes a permanent excuse to not automate anything.
This talk explains why automation stalls even when the tools are fine: unclear definitions of “safe” and “correct,” fragile inputs, and changes that can’t be proven before they ship. You’ll get a pragmatic way to turn automation from a special project into a normal way...
This talk is about how, I, as a person with disabilities managed to get a job in Norlys, one of Denmark biggest telecom companies.
It is my story from education up until now and how I, as an untraditional workforce, manages to get telecom issues solved.
Additionally, I have invited my manager to give his point of view from first meeting at DKNOG 15 through the hiring process and how it is...
This is the "classic" DKNOG Quiz.
You will be tested on your knowledge of Routing, RPKI, Unix history, and most important on the content of the talks of the whole two days.
So, pay attention to all the talks, take note of all the details of slidesets, and prepare your fingers to answer as quick as possible.
Prizes will be given to the three highest scorers!
