The deployment of IPv6 data storage on WLCG and UK GridPP (Main Session)
- David Kelsey (STFC UK Research and Innovation)
10:00 - 10:30
Room: Broadgate 1 & 2 The Worldwide LHC Computing Grid (WLCG) project is a global collaboration of more than 170 computing centres in 42 countries, linking up national and international grid infrastructures. The mission of the WLCG project is to provide global computing resources to store, distribute and analyse the ~50-70 Petabytes of data expected every year of operations from the Large Hadron Collider (LHC) at CERN on the Franco-Swiss border. The UK component of WLCG is called GridPP. Some years ago, it was noted that several important data centres in WLCG were running out of IPv4 address space and so a task force was started to investigate the IPv6-readiness of the LHC experiment software and Grid middleware and a project was started to make the majority of the data storage services available over dual-stack IPv6/IPv4. Once achieved, CPU resources deployed on Clouds or Grids could be IPv6-only. Today in the 18 UK data centres operated by GridPP, more than 50% of the current 34 Petabytes of storage is available over IPv6. This talk will present the work done to enable IPv6 services together with some details of the data transfer services used. Our transition plan to IPv6 and its execution will be included. Not all has been smooth or easy and some details of problems encountered along the way will be described.
10:30 An Overview of IPv6 Security - David Holder (Erion Ltd)
An Overview of IPv6 Security (Main Session)
- David Holder (Erion Ltd)
10:30 - 11:00
Room: Broadgate 1 & 2 Security is one of the most crucial factors in modern networks. Network operators are painfully aware of this. IPv6 brings new challenges, features and opportunities for network security. This presentation provides a comprehensive overview of IPv6 security, why it needs to be taken seriously, how it differs from IPv4, the problems it presents and current IPv6 security techniques and best practice. As IPv6 becomes more widespread, no one interested in network security or network forensics can afford to ignore security IPv6

11:30 - 12:00
Room: Broadgate 1 & 2 UKNOF meetings happen thanks to the active support and participation of many people - volunteers, speakers, sponsors, partners. Keeping UKNOF sustainable and relevant is important to everyone, and every so often we give the community a chance to hear about how all this works, various changes we're making, and to hear your feedback.
12:00 DNS Flag day and beyond - how will it affect you? - Cathy Almond (Internet Systems Consortium)
DNS Flag day and beyond - how will it affect you? (Main Session)
- Cathy Almond (Internet Systems Consortium)
12:00 - 12:15
Room: Broadgate 1 & 2 The major Open Source DNS Software providers along with a number of other organisations have declared a flag day, after which they will cease accommodating non-RFC-compliant behaviour when interacting with other servers. This talk (a collaboration between the software providers and other committed parties) will first briefly summarise the versions of software that have removed the excess code complexity needed to interoperate with broken servers, and/or confirm the date on which their service will do the same. Then it will cover in a little more detail what this means to ordinary operators who aren't necessarily DNS experts or operators - what effects might this have on them, either as organisations with their own authoritative DNS zones (self-managed or hosted), and/or for DNS resolution of other names and domains via their recursive servers. \- What problems might be encountered? \- How to resolve them?
12:15 The big IPv6 and RPKI quiz! - Massimiliano Stucchi (RIPE NCC) Nathalie Trenaman (RIPE NCC)
The big IPv6 and RPKI quiz! (Main Session)

12:15 - 12:30
Room: Broadgate 1 & 2 Do you think you know everything about IPv6 and RPKI ? Are you ready to test your knowledge, or learn from your mistakes while participating in a quiz ? We are going to challenge you with 20 questions, and everyone in the room can participate in the quiz to win prizes!

Large Scale Edge DDoS Protection (Sponsor-led Content)
- Sean Newman (Sponsor)
14:00 - 14:20
Room: Broadgate 1 & 2 An update on the latest state of the DDoS threat with details of how high-performance traffic filtering in the latest generation of edge routers and switches is opening up new opportunities for security policy enforcement, in general, as well as enabling real-time DDoS protection at a scale not previously seen.
14:20 Beyond Whois: Connecting the Digital Dots - Mike Lewis (Cyber Toolbetl)
Beyond Whois: Connecting the Digital Dots (Main Session)
- Mike Lewis (Cyber Toolbetl)
14:20 - 14:50
Room: Broadgate 1 & 2 The presentation goes through the story of how Cyber Toolbelt Investigators were able to unravel a massive fraud network using only DNS and with only a single domain name to go on.
14:50 IXPDB and Euro-IX tools - Bijal Sanghani (Euro-IX)
IXPDB and Euro-IX tools (Main Session)
- Bijal Sanghani (Euro-IX)
14:50 - 15:05
Room: Broadgate 1 & 2 This presentation will include: - an introduction to the IXPDB (IXP Database) - Details on the IX-F JSON Member List - tools now available for networks to find each other - a roadmap of new tools coming in 2019 I also hope to get feedback from the attendees on new ideas and tools they'd like to see.
15:05 TTLd: Total TCP Loss detection - Louis Plissonneau (Facebook)
TTLd: Total TCP Loss detection (Main Session)
- Louis Plissonneau (Facebook)
15:05 - 15:35
Room: Broadgate 1 & 2 TTLd is a new approach to network monitoring. This hybrid approach exposes in the TCP header information of loss from the host, and this information is accounted for at network device level. This allows for precise loss detection and effective accounting and aggregation of this information. The ground breaking feature of this project is that every single packet in the network becomes a probe! We show results from an internal visualisation tool able to show the state of all the datacenter at once and then zoom to the noisy parts.

16:35 400G - don't get confused with this transceiver generation & IEEE 802.3bs - Thomas Weible (Flexoptix GmbH)
400G - don't get confused with this transceiver generation & IEEE 802.3bs (Main Session)
- Thomas Weible (Flexoptix GmbH)
16:35 - 17:05
Room: Broadgate 1 & 2 Transmission speed of 400G is becoming a reality, with new challenges for optical and electrical components in high speed systems emerging as well. PAM4 modulation is one key component for 400G transmission with transceivers following Ethernet IEEE 802.3bs, this talk will be a show and tell into PAM4. With this knowledge, the design decisions behind the new formfactors OSFP, QSFP-DD, SFP56-DD and µQSFP are easier to understand. This talk will help you to: - Design / build new kind of applications or connections with your networking gear in the field - 100G will no longer be the fast option for IXP interconnections soon DR, FR4 and LR4 at 400G will be available - Avoid pitfalls when designing your racks - Be aware how power consumption and new plugs will be part of the new world of 400G transceivers. Author Bio: Thomas Weible - Co-Founder and CTO of Flexoptix GmbH. He formerly lead the groundbreaking software development within the company. Thomas has moved more and more towards the field of transceiver technology and his so called „support with no levels and no bullshit“. Enthusiastic in everything he does, he gives realistic and practical answers to get transceivers working and operational. As a regular speaker at several conferences around the globe he is able to target the needs of network engineers. Thomas likes tractor driving and nature, and is a huge fan of smart pragmatism. Thomas studied information technology in Darmstadt, Germany.

Fire Fire Fire! (Or maybe not...) (Main Session)
- Steve Wright (4D Data Centres, LINX)
17:05 - 17:35
Room: Broadgate 1 & 2 In July 2018 I experienced my first (and hopefully last!) FM200 fire suppression system discharge. While we all might have heard about fire suppression systems, and the risks and benefits - I aim to cast a bit of further light onto real world experiences on the little red bombs that we all put in our data centres. This talk will aim to: - a brief summary of the different fire suppression systems in use in data centres - some real world experiences from people who have had their systems either release by design or accidentally - the after effects (building, systems, process, people)
