Vor Kurzem hat die Pro Senectute beider Basel ihren «Swiss Crypto Marvels»-NFT gestartet und kurz davor auch ihr Metaverse-Engagement bekanntgegeben. Die Reaktionen darauf reichen von «mutiger Schritt» bis zu «so ein Käse». Motiviert von diesem Interesse gehen wir der Frage nach, was das Metaverse ist, wieso es davon so viele gibt, was NFTs und Kryptowährungen damit zu tun haben und was nun von al...

A lot of things have been added and improved since the last talk at DENOG10. We want to take this opportunity to provide an update on what we have done on and what our agenda looks like. None about this event: https://pretalx.com/denog14/talk/US3RZ7/

This talk will present a scalable, redundant and vendor-neutral approach to provide firewalled network segments within an EVPN fabric. Instead of stretching layer-2 segments, VRF route leaking is used to route traffic from network segments to the firewalls in a generic way. Using anycast gateways within the EVPN fabric, a consistent gateway behavior across firewalled and non-firewalled network seg...

In this talk, Pim will demonstrate high performance routing using open-source VPP and its underlying Data Plane Development Kit. This talk highlights the authors work on integrating the Linux Control Plane which makes BGP, OSPF, etc available with VPP, including smart ways to automate configuration of the router's data- and controlplane layers. We’ll then turn to a popular DPDK based network load...

Route leaks containing more specific announcements of Internet Exchange Peering-LANs pose a risk to the reliability of Internet infrastructure. RPKI validation and filtering can mitigate some of the dangers - if the IXP operator created proper ROAs. In this lightning talk we will take a look at what can go wrong, how RPKI ROAs can save us and what the current state of the rollout is. None about th...

PeeringDB has been around for almost 20 years and is the go-to place for interconnection data. Whether to find new peers around you, looking for facilities when expanding your networks or retrieving configuration data for BGP sessions. PeeringDB has all of these data. The database is a non-profit, community-driven initiative run and promoted by volunteers. It is a public tool for the growth and go...

Pastel de Natas are delicious and while sharing some in Belgrade, the topic of "all traffic goes via Frankfurt" came up. So what does the traffic numbers actually say. And is the result something we should discuss? None about this event: https://pretalx.com/denog14/talk/PLCJKJ/

There are very few troubleshooting tools that work across the public internet reasonably reliably. Well, it really boils down to Ping and Traceroute. Of those two, the latter is sometimes referred to as the "the number one go-to tool" for troubleshooting problems on the internet [1]. That is not, because it provides all the information we need or would like to have but at least, for the most part,...

Are you hearing the word sustainability more and more often but you are not sure what exactly that means for you, your company, or the industry? In this talk you will learn about the new upcoming regulations, tracking options, network vendor sustainability data, reporting types and forms, organizational integration of sustainability data, as well as some certificates you can apply for. You'll also...

DE-CIX has been working on the introduction of EVPN on its peering platform since the beginning of the year. Considering the increasing number of participants, especially in Frankfurt, the introduction of EVPN including ProxyARP/ND is already overdue in order to get the exponentially growing broadcast/multicast traffic in our peering LANs under control and to reduce the load on customer routers. A...

Monitoring of traffic flows is a central aspect of modern network engineering from planning peering connectivity to anomaly detection. This talk discusses how we handle flows from different sources, enrich them with additional contextual data such as customer names or geo locations, and use that information in different contexts using our own Open Source [flowpipeline](https://github.com/bwNetFlow...

In a heterogeneous environment the devices need to cooperate. This talk aims to define the common ground for planning and implementing QoS. Different designs are compared and - if possible - matched. None about this event: https://pretalx.com/denog14/talk/Q3SNBK/

Day1 is coming to an end, let's see where we're headed... None about this event: https://pretalx.com/denog14/talk/XRL39P/

In this presentation Pavel will share practical real field aspects of using BGP Flow Spec for DDoS mitigation. I will talk about level of vendor support level and known implementation issues. None about this event: https://pretalx.com/denog14/talk/8F8A9H/

Most companies are already aware that diverse teams can help with innovation, performance and prevent "group think". But aside from the usual "we're open to applications from all backgrounds"-sidenote, many companies and hiring managers aren't sure how to best go about diverse hiring. If you keep getting applications from the same crowd and want to do something about it, come along and reflect on...

With vPC Fabric Peering, direct links between vPC peers can be eliminated in most situations as vPC traffic goes through the fabric. It even simplifies the VXLAN-EVPN configuration in some cases. This lightning talk gives a short overview of how to configure vPC Fabric Peering and sheds light on a few pitfalls. None about this event: https://pretalx.com/denog14/talk/RMDY8Q/

Over the years many talks and workshops have been held to improve and spread the overall knowledge of BGP and it's knobs, configs and features. These days there are only a few up-to-date and vendor-agnostic references when it comes to design, control plane and forwarding filtering in modern carrier and/or ISP like networks. We think that DENOG is the perfect organisation to form a group of people...

RFC9234 allows to assign a role to each BGP neighbors. Roles can be matched when setting up sessions and a transitive attribute is added to prefixes which should be announced to customers only. None about this event: https://pretalx.com/denog14/talk/ZYUS8K/

The presenter has been active in different data centers over many years. Many times has he helped out other parties with various tools or materials. Even looking for help from time to time, the fixe idea formed to have a data center machine to be able to buy nuts and screws, tools or cables. But this was nowhere to be found. This seemed like something to start an interesting project... The journey...

Following some discussion at RIPE84Fredy Kuenzler and I put forward an Internet Draft to define a well-known advisory BGP community to denote prefixes are used for Anycast. To quote from the abstract of the ID: > In theory routing decisions on the Internet and by extension within ISP networks should always use hot-potato routing to reach any given destination. In reality operators sometimes choose...

The wave of 400GE IP routing satisfied the increased bandwidth demand observed during the global pandemic with many optical module variants emerging depending on use case, cost and technology. Technology has evolved since, and routers with 800GE interfaces are now available giving early adopters many benefits from power and density perspective. This presentation provides a unique insight in what t...

This talk gives an insight of 400G-ZR and 400G-ZR+ for wide-area links. Whilst most presentations are theoretical, this one is based on real-world deployments and the side effects you can observe. None about this event: https://pretalx.com/denog14/talk/3NZMVW/

This talk will talk about the Euro-IX activities. 1. The IXP{DB} project - I'll provide a brief history on when and why the project started, the progress through the years and where we are now and a road map to show the future plans. 2. The Peering Toolbox - a tool for learning about peering for new entrants in the industry. 3. The IXP Report - I'll show some statistics from the report to give som...
