Hands-on Learning: Virtual IPv6 Security Lab Environment (Main Session)

• Ondřej Caletka (RIPE NCC)

Room: Charter 1, 2, 3 Recently, we launched a new free e-learning course on IPv6 security in the RIPE NCC Academy. With this course, we also offer a way to practice some attacks and protection against them on your own computer. I will present this virtual lab environment and describe the open source components it is based on.

RIPE 554bis (Main Session)

• Sander Steffann (S.J.M. Steffann)

Room: Charter 1, 2, 3 The RIPE 554 document “Requirements for IPv6 in ICT Equipment” is used all over the world when purchasing IPv6-capable equipment, software and services. It has been translated into many languages and is even part of the purchasing guidelines of governments. However, RIPE 554 was published in 2012 and contains references that had become outdated or obsolete. It also doesn’t contain any requirements for technologies developed later on. Therefore, it is time to review this document, and update it for the current decade. This presentation will be a short update on our progress so far, and a call to participation for the UKNOF community - we want your input. We only have a short time to collate your opinions, as the document will hopefully get consensus and be declared final at the next RIPE meeting (https://ripe83.ripe.net/) a few days after the UKNOF meeting. You can find the latest draft on the RIPE IPv6-WG mailing list (https://www.ripe.net/ripe/mail/archives/ipv6-wg/2021-November/003713.html).

An evolution of the Network Engineer (Main Session)

• Jose Leitao
• Elena Sanchez

Room: Charter 1, 2, 3 We’ve designed a talk to explore what happens when a business grows, and the role of the network becomes critical: you have more servers to connect, more data to transport, more services reliant on each other. You can’t afford to provide a bad experience to your customers, nor “throw more people at the problem” to solve it. You have to move fast and be reliable in today’s world — even when sharks eat your fiber cables. Your knowledge and skills will be the tools to approach the growth, but you will deal with never-seen-before challenges — including esoteric ones. You will also begin to realise that 1% means thousands, millions or hundreds of millions of people, and indeed, you won’t have time for manual fixes. We identified common knowledge and skill gaps that Network Engineers have when faced with the challenge of operating a large-scale network. We will explain why they are important and give an approach to bridging them to prepare yourself for a future ahead.

A New Kind of Peer (Main Session)

• Rebecca Class-Peter (Euro-IX)

Room: Charter 1, 2, 3 As the Internet matures, organisations that have traditionally bought transit are joining IXPs and peering with other networks. This talk will look at who these networks are, why they are doing this, and the risks that could arise for both IXPs and their participating networks. It will then introduce Euro-IX's Peering Toolbox project and explain how it is intended to help manage the risks. It will further describe opportunities for participation in the project from people with expertise to share.

TreeDN: Tree-based CDNs for Live Streaming to Mass Audiences (Main Session)

• Lenny Giuliano (Juniper Networks)

Room: Charter 1, 2, 3 In the late 90's, there was much excitement and exuberance over the potential of Internet Multicast. Today, interest in Internet Multicast is perhaps at an all-time low despite the fact we may be approaching an inflection point of demand fueled by an explosion of live streaming audiences sizes, increasing bitrates from 4K/8K/AR and a greater dependence on the network since the start of the COVID pandemic. In this presentation, we will examine a brief history of Internet Multicast and what went wrong in the past. We will discuss recent architectural developments such as AMT and ASM Deprecation, that eliminate the fundamental issues that made deployment so challenging in the past, and pave the way for the TreeDN architecture that network operators can offer to their customers to support live streaming to mass audiences at a fraction the cost of traditional, unicast CDNs. Finally, we will show how TreeDN is not just a hopeful promise for the distant future, but available and in use today.

WFH is a nice idea, but ... (Main Session)

• Cathy Almond (Internet Systems Consortium)

Room: Charter 1, 2, 3 There are companies whose staff all work from home already - so why was being obliged to work from home due to Covid-19 restrictions so hard for many (excepting the obvious issues of childcare and at-home schooling support). This is a short wander and ponder over some of the challenges and benefits of a permanent Work From Home position versus an enforced one, also taking a look at what what makes home-working successful versus the barriers that can instead lead to failure.

Half-Way to Automation, All the Way in Orkney (Main Session)

• Marek Isalski (FAELIX)

Room: Charter 1, 2, 3 How we designed, built, and worked with the customer to uplift a rural fixed-wireless access ISP's network from layer-2 to layer-3 with multiple egress points, to support a 5G build and a huge capacity upgrade. Full of photos of masts on hills and windy network cabinets, this talk will also cover how we used NetBox as our source of truth to architect the network virtually, and then generate configurations for all the relevant devices.

The Ground Beneath Our Feet: Recent (and Upcoming) Developments in Internet Governance (Main Session)

• Chris Buckridge (RIPE NCC)

Room: Charter 1, 2, 3 Issues related to Internet regulation and governance have been high on many agendas recent times. This presentation will give an overview of some of the most relevant developments, the potential impacts on the Internet operational community, and expectations in the coming year. Discussion will draw on developments in the UK, the EU, and on the global scene, with focus on the evolving structures at the UN level and new efforts at regulation such as the EU's proposed NIS2 Directive.

DDoS attacks from IXP customer's perspective (Main Session)

• Pavel Odintsov (FastNetMon)

Room: Charter 1, 2, 3 Hello! Thank you for reading my proposal! I did this presentation at EuroIX session with focus on IXPs personnel and their engineers. In this presentation at UKNOF I'll focus on customer's side of problem with DDoS attacks coming from IXPs.

perfSONAR at your fingertips: Open. Extensible. Worldwide (Main Session)

• Szymon Trocha (Poznan Supercomputing and Networking Center)

Room: Charter 1, 2, 3 The perfSONAR project is a world-wide network performance monitoring infrastructure and software built thanks to a collaboration of international partners. Its modular architecture with various backends and extensive choice of tools enables users to setup measurements and visualization dashboards combining multiple monitoring sources. perfSONAR is focused on delivering a multi-domain network performance measurement and monitoring with a particular emphasis on Research and Education networks and international data transfers. In this presentation we will share how to address the challenge of monitoring multi-domain infrastructures and show the building blocks of the perfSONAR measurement capabilities. We will show how perfSONAR monitoring solution offers a variety of tests to determine performance metrics between various networks and supports problems troubleshooting to support efficient collaboration amongst different organizations. We will also discuss the latest developments and EU community engagement in the perfSONAR project.
