QoE Matters – How Application-Level Monitoring Pinpoints Network Issues (denog17)
Network operations engineers maintain the backbone of our digital experiences, ensuring robust connectivity and managing complex routing. Yet, even with great network health, where are the current limits of today’s routing technology? What does it mean when your manager calls you and says “Our customers can’t watch Netflix!”? Can we measure how the end users experience the high variety of OTT-services, beyond classical speedtests? In this talk, we will investigate real-world scenarios where network issues, even seemingly minor ones, impacted video QoE. We'll demonstrate how solutions to these problems often go miles beyond classic...
Th3 Flock of Bird s (denog17)
As Bird is evolving over the years and we now have Bird version 3 available at our fingertips, maybe we should know the capabilities of it and what performance we can expect from it.
Get some numbers in comparison with other routing stacks.
Let's take a quick look on the shiny new feathers Bird prepared for us.

200 GbE network processing with 100 W - or "can I *make* a chip for that?" (denog17)
This talk presents how to to offload networking tasks onto dedicated hardware/smartNICs/NPUs (network processing units) - chips, and why this is a great idea. First, we take a look at chips in general - how they are made, integrated into networks, and why time is playing to the advantage of dedicated chips vs. CPUs/software. Then, focus is on how offloading network tasks is a particularly beautiful example of the advantages of hardware-implementing logic, with examples like TCP offloading, cybersecurity applications, or traffic shaping. To be fair and balanced, there will also be a look at the downsides...

EVPN for the rest of us – what happens when software people try to use EVPN (denog17)
Last year we migrated our datacentre networks from a flat layer 2-based architecture to EVPN-VXLAN. As an organisation whose primary technical background is in software, a network project of this complexity has been a journey into new and uncharted territory. Our previous network design had been showing signs of reaching its limits for several years, so in late 2023 we started designing a replacement based on EVPN-VXLAN, terminated directly on our Linux hypervisors. After not quite nine months of development the project culminated in an intensive week-long migration in our production datacentre – with zero...
Sorry we messed up (denog17)
How we route-leaked everything to everyone due to a fun Arista bug.
A post-mortem kind of story about us changing Arista RCF function names, resulting in a global route leak. The talk includes the history of why we intended to make a change, how we rollout configurations, why it resulted in an unexpected behavior and how it was fixed.

Ultra Ethernet: Addressing AI/HPC Interconnect Challenges Beyond the InfiniBand Monopoly (denog17)
For years, InfiniBand has dominated high-performance interconnects. Yet for strategic and technical reasons, there has been a huge industry ask to develop a new next-generation protocol for use in AI and HPC environments. This session introduces Ultra Ethernet, an innovative standard designed to tackle the limitations seen in RDMA around scalability, latency and congestion management, crucial for democratizing future AI/HPC build outs. Join us for a comprehensive exploration of the technologies poised to redefine Storage or GPU interconnectivity and challenge the status quo. We also discuss the future of the UEC and how collaboration among...

Inventing the wheel - Network Orchestration at scale (denog17)
At DE-CIX, we're redefining network orchestration from first principles. Confronted with the limitations of existing systems, we set out to design a modern orchestration stack—one capable of managing a truly global network, seamlessly interfacing with a variety of upstream and downstream systems, supporting fully managed network devices, and, above all, delivering uncompromising reliability. In this talk, we share our transformation journey—from our starting point to our vision for the future. We'll delve into the architectural choices, design principles, and decision-making frameworks that guided our approach. We’ll also explore how we rigorously test our systems and...
