Room: Broadgate 1 & 2

Positioning Sky Core network for massive VOD growth (Main Session)

• Tim Rossiter (Sky Networks)

Room: Broadgate 1 & 2 Sky Broadband is at the leading edge in deploying new network implementations and router products to handle huge growth in broadband traffic and subscriber numbers. This presentation describes network growth and evolution through four generations of router technology as subscriber numbers have grown to 6 million and total traffic from 40 Gbit/s to 8000 Gbit/s. It describes the multiple hardware and architectural solutions used, transition process and experience gained. Topics include: • Early deployment of Cisco NCS5516 routers to provide an order of magnitude increase in routing capacity. • Extensive programme to bring CDN on-net and to localise where possible in order to minimise peering and transmission costs. • Adoption of latest 100G optical transmission and interface standards to maximise fibre efficiency and reduce cost. • Planning and Forecasting Process • Rollout of Ipv6 to all subscribers to position Sky network for future growth

Commodity Networks (Main Session)

• Louis Plissonneau (Facebook)

Room: Broadgate 1 & 2 The high capacity, reliable and redundant Facebook datacenter networks are built using a CLOS topology. We often talk about how these topologies scale up to build massive server networks. This talk describes how these same topologies can be scaled down to meet the needs of a small to medium sized network using industry standard vendor provided switches.

Defending IoT Pulse Wave DDoS Attacks (Sponsor-led content)

• Sean Newman (Sponsor)

Room: Broadgate 1 & 2 The sophistication with which cybercriminals are creating IoT botnets continues to increase, as does the type of attacks they are launching with them – the latest innovation sees destination modulation being used to deliver attacks which are effective at doing harm even when conventional DDoS protection is in place. Understand why this new vector requires an always-on approach to DDoS mitigation.

Engineered Chaos: Breaking Prod and Getting Away With It (Main Session)

• Oliver Leaver-Smith (None)

Room: Broadgate 1 & 2 A talk around chaos engineering and how we do this at SBG

Open Source Network Performance and Validation Testing (Main Session)

• James Bensley (None)

Room: Broadgate 1 & 2 Most networks are built from closed source proprietary solutions and tested with black box testers. Many of operators suffer from limitations regarding feature requests/security fixes/bug fixes/interop issues/undocumented behaviour or troubleshooting methods. Various open source software solutions exist for Linux, which provide the facilities to test a range of generic network devices. Descriptions, comparisons, use cases and real world results are provided for some of the different software tools available; to show how they can be used to profile and verify network devices and functions at layers 2/2.5 (Ethernet/MPLS) in detail. These can help operators better test vendor claims, validate RFPs and catch issues before the equipment is deployed into the live network.

The Challenges of DNS Resolution in China (Sponsor-led content)

• Tim Hale (ThousandEyes)

Room: Broadgate 1 & 2

PGP Signing Session

The UK’s Active Cyber Defence agenda: One year on (Main Session)

• Richard Crowther (NCSC)

Room: Broadgate 1 & 2 At UKNOF 35, the National Cyber Security Centre shared its plans to address systemic cyber security issues at scale through its Active Cyber Defence programme. Just over a year on, we’ve learned and achieved a lot. This talk will provide an update on our progress so far.

Using a DNS Response Policy Zone to protect against malware (Main Session)

• James Richards (Nominet)

Room: Broadgate 1 & 2 A Response Policy Zone (RPZ) allows operators of recursive DNS systems to apply conditional policies on incoming queries. This talk will discuss the use of the RPZ technology, some implementation details, and how the RPZ may affect the profile/monitoring of DNS traffic across a system.

The Investigatory Powers Act 2016 (Main Session)

• Neil Brown (decoded:Legal)

Room: Broadgate 1 & 2 The Investigatory Powers Act 2016 is the biggest change to the UK's surveillance law framework in 15 years. Neil will explain the changes, and set out the current position in terms of obligations which can be imposed on telecommunications operators.

Microsoft IT Journey to IPv6 (Main Session)

• Veronika McKillop (Microsoft)

Room: Broadgate 1 & 2 This presentation will cover the journey that Networking team in Microsoft IT took from IPv4-only to Dual-Stack network. However, the team is not stopping there as Dual-Stack is IPv6 half-done. The team aims to go IPv6-Only and I will share some details of our experience so far and what future may hold for any user of Microsoft products.

IPv6 Deployment Survey and BCOP (Main Session)

• Jordi Palet Martinez (The IPv6 Company)

Room: Broadgate 1 & 2 This presentation will introduce the results of the Global IPv6 Deployment Survey started about 2 years before the event is taking place.

UKWISPA Intro Talk (Lightning Talks)

• David Burns (UKWISPA)

Room: Broadgate 1 & 2 An Introduction to UKWISPA from the Chair of the Group. Showing what the group is doing and what the goals are.

What’s five nines anyway? - Building Temporary Networks (Main Session)

• Thomas Penrose (Attendee)

Room: Broadgate 1 & 2 An insight into building and running a 5000+ port, 5Gb/s+ network in 1.5 days, then tearing it down again 4 days later. The talk will cover the challenges in running a show of this size and some funny learnings, moments and problems along the way!
