Designing automation for brown field networks (DKNOG12)
- Allan Eising (Telia Company)
9:45 AM - 10:15 AM
It is one thing to write automation for new networks and services, but what if you need to replace old automation, and integrate seamlessly into an already running network? This talk goes through the experiences and principles designing and implementing network automation in Telia Company, based on a project that ran over two years in Norway. About the speaker: Allan Eising is the lead automation architect in Norway. He has more than 15 years of experience running advanced B2B service provider networks, and is driven by a desire to automate as much as possible, so network engineers can be free to solve interesting problems, instead of pasting configuration in to terminal windows.

In 2019 the danish ISP's Sydenergi and Eniig merged into Norlys. Shortly after, Norlys announced it would open their FTTH network for wholesale To support wholesale services in a scaleable and automated fashion, new equipment needed to be installed in 270 locations in just 10 months This presentation will cover this journey, including rollout of a new OOB network, the introduction of Netbox as source of truth, and fully automated day 0 and day 1 config

11:30 AM - 12:00 PM
**XR optics** technology purpose-built to break the inherent limitations of traditional point-to-point optical transmission solutions. XR optics paves the way for disruptive network economics as 5G, fiber deep, and hyperscale cloud connectivity impose new challenges on operators. With game-changing innovation in coherent optical subcarrier aggregation, XR optics introduces a new pluggable and software-enabled architecture. XR optics dramatically lowers cost and enhances deployment flexibility as the same coherent pluggable can be software-configured to operate in point-to-point or point-to-multipoint configurations. This will change optical networking as we know it today. XR optics is an open technology initiative with the support of network operators, equipment manufacturers, and subsystem manufacturers.

BGP monitoring - the whys and Hows (DKNOG12)
- Nina Bargisen (Kentik)
2:40 PM - 3:10 PM
BGP monitoring has been around for years for service providers and most larger organizations have some sort of monitoring in place. The list of excellent presentations arguing the benefit of increased routing security is very long - so is the list of hijacking examples. But say we were in an ideal world where hijacks do not happen because RKPI is fully deployed? Do we care about BGP monitoring then? Yes, we do - routing security secures that your address space is announced where and how you want it, but if you care about latency ( or is a control freak like me), you will also care about whether your prefixes are routed on the internet as you planned them to be. This talk will go through some of the options you have to detect whether that is the case or not and discuss the pros and cons of each of them."

MPLS Core Automation with Ansible AVD (DKNOG12)
- Emil Landström
- Niels Larsen (Arista Networks)
3:45 PM - 4:15 PM
At Arista, open-source automation tools like ansible and infrastructure as code workflows have been bread-and-butter in the DC network for a while, now we are bringing these workflows and methodologies into the SP/Core space with our ansible collection "AVD". AVD stands for Arista Validated Designs and is a 100% open-source project that is built and maintained by over 50 individual contributors from Arista and the customer community. It provides a flexible automation framework for ansible, made to design, stage, provision, maintain, test and document complete production-ready networks running evpn-vxlan and now also evpn-mpls, vpn-ipv4/ipv6 overlays with ldp- and/or segment routing-based underlays. AVD manages every part of the device configuration including underlay/overlay protocols, services, endpoint connectivity, and works in a simple, declarative, config-replace way. AVD can function with or without Aristas CloudVision Portal and is 100% open and free-to-use. The session will consist of some topics briefly explaining AVD/ansible mechanics and a live demo where different types of services will be deployed using AVD. All the demo repositories will be made available for download after the session.
4:15 PM Timing and synchronisation in networked broadcast systems - Måns Nilsson (Sveriges Television)
Timing and synchronisation in networked broadcast systems (DKNOG12)
- Måns Nilsson (Sveriges Television)
4:15 PM - 4:45 PM
Time and frequency synchronisation in television production have been governed by the technical demands of the cathode ray tube in close to 90 years. The move to flat screens and IP networks as display and carrier of video streams has put an end to this. In this talk, we'll look at how the requirements for synchronising a modern TV production facility affect network design, and how to co-exist in a mixed world where legacy and bleeding edge leapfrog in making new productions.

10:15 AM SRv6 Technology and Deployment Update - Pablo Camarillo (Cisco Systems)
SRv6 Technology and Deployment Update (DKNOG12)
- Pablo Camarillo (Cisco Systems)
10:15 AM - 10:45 AM
It’s been a couple of years since the first worldwide SRv6 deployment. Today we enjoy a rich ecosystem -routing vendors, merchant silicon, as well as opensource- and more importantly deployments in some of the largest networks. In this session we would like to highlight the state of SRv6 today, go through the existing deployment use-cases (with content contributed by those operators) as well as the technology behind it. In the second half of the session, we would like to go through a recently announced technology: Path Tracing. This is a complementary tool to SR networks that solves a 40-year old IP problem: we do not know have a record of the exact path taken by packets in the network. This new technology -which is being standardizes at the IETF- allows measuring the actual packet experience in the network. It does so by by extracting the juice out of the router, so that it is implemented at linerate without any CPU processing or co-processor offloading.

IP routing at 400GE, 800GE and beyond (DKNOG12)
- Jonas Vermeulen (Nokia)
10:45 AM - 11:15 AM
Global bandwidth consumption increased 3 times in 2021 as digitization at work, home and school accelerated during the global pandemic. The wave of 400GE IP routing satisfied this bandwidth demand, with many optical module variants emerging depending on use case, cost and technology. With 800GE around the corner, early adopters will gain many benefits. But with the diversity of optical pluggable modules, form factors, specifications and power considerations, making the right choice is not easy. This presentation provides a brief overview of the technologies and trends that enable IP routing at 400GE, 800GE and beyond. It touches on considerations such as optical interface technologies, power, cooling and system design that will influence IP routing in the future.

Kea 2.0 - modern DHCP (DKNOG12)
- Tomek Mrugalski (ISC)
11:35 AM - 12:05 PM
This presentation provides an update about Kea, a modern, open source DHCP server from ISC. It starts with some background history about ISC DHCP, its problems and the reasons why migration to Kea is desired. The major advantages of Kea (REST API, optional database backends, extensibility with hooks, performance) are discussed. The latest features and additions implemented in Kea 2.0 and beyond are discussed: scalable multi-threading for HA, TLS support, cache threshold). A sneak peak of Stork, a dashboard for Kea with Prometheus and Grafana capabilities conclude the talk.
