Introduction and Welcome

Your Sixty Seconds Starts Now (Main Session)

• Brian Nisbet (HEAnet)

In times of yore it would take users some time to notice that their Internet connection was down. While NOCs still tried to fix things as quickly as possible, reasonable SLAs were accepted and issues only occurred if they were breached. Time has moved on and tolerance for service outages has dropped. The SLAs we offer our clients (and by definition our end users) often haven't really moved on to reflect this new reality. These days many services have an effective SLA (or really a Service Level Obligation) of closer to a minute ie the time between the service (such as a Virtual Learning Environment) going offline and the end user noticing.

PNDA.io: when big data and OSS collide (Main Session)

• John Evans (Cisco)

In this presentation we propose that big data analytics can be used to realise the next generation of operational analysis functions, analysing the data produced by these services and providing operational and business insight as fast as they can be provisioned.  We show how the PNDA.io open source data platform can be used to realise these functions and present use cases which demonstrate how this can be used to leverage the rapid industry innovations in big data analytics. PNDA.io is a Linux Foundation Collaborative Project.

The March of Merchant Silicon (Arista Sponsor Presentation)

• Alex Nichol (Arista)

The widespread adoption of merchant silicon has caused a massive disruption in the data centre market, with traditional hardware networking vendors struggling to maintain differentiation as silicon evolves on a year on year basis to provide improved cost per performance. With previous generations of merchant silicon, table scale, and forwarding logic limited their deployment to within the data centre, with routing still seen as the playground of the traditional vendors. This approach is now being disrupted by the latest evolution of merchant silicon, which blurs the line between switching and routing logic and software innovation which can extend the default hardware capabilities of the merchant silicon.

Evolving the Transport-Layer (Main Session)

• Stephen McQuistin (University of Glasgow)

Many applications would benefit from a richer set of services than is provided by TCP and UDP. Ossification makes it difficult to develop novel protocols, restricting solutions to using widely-deployed protocols as substrates. In this talk, I'll outline our broad approach to transport-layer evolution, and introduce TCP Hollywood as an example. Further, I'll appeal to network operators for help in understanding their middlebox deployments, and how these might impact transport-layer evolution.

Deploying DDoS Protection Against The Latest Surgical Attacks (Sponsor-led Content)

• Sean Newman (Sponsor)

Following on from the previous UKNOF update on the changing DDoS threat landscape, this session covers how traditional approaches to DDoS protection are failing as a result – Out-of-band monitoring, with simple black-holing or re-routing to centralized DDoS scrubbing facilities are not meeting the demands of today’s Internet enabled businesses, where every minute they are offline adds up to huge revenue losses. The session concludes with some practical examples of how the latest solutions are now being deployed in typical provider networks, to deliver real-time, automatic, protection.

IPv6-only mobile devices on EE (Main Session)

• Nick Heatley (BT)

EE, the mobile network of BT, enabled IPv6 for many EE consumer customers on Pay Monthly contracts in H2 2016. The cellular network provides the eligible IPv6 smartphone with only an IPv6 address. Access to IPv4 content and services is available through a technology known as 464xlat (RFC6877). This session will cover how the mobile network (APN) has been enabled for IPv6 and how 464xlat ensures a seamless internet experience on an IPv6-only mobile network.

A Cambridge Lesson on building your own fibre network (Main Session)

• Jon Holgate (Cambridge University)

In 1992, the University of Cambridge completed the installation of its own metropolitan wide fibre optic network, principally to support the transfer of ‘digital books’ for the Classics departments. On its 25th anniversary, Jon Holgate takes the opportunity to reflect on the lessons learned from deploying and managing the largest academic private fibre network in Europe. This presentation reflects on how assumptions made 25 years ago have transpired, the statistical probability of fence post boring machines and the price of peas.

Radio Fun (Lightning Presentations)

• Donal Cunningham

War stories about radio and fibre networks, including lots of pretty pictures of challenging environmental conditions at high sites, recommendations for best practices in fibre maintenance and a new data centre metric.

LPWAN developments (Lightning Presentations)

• Steve Karmeinsky (NetTek Ltd / DBVu Ltd / City Meets Tech Ltd)

There are various LPWAN technologies being rolled out at the moment such as SIGFOX and LoRAWAN which sit in the 868MHz (license exempt) band. SIGFOX is currently being rolled out by Arqiva and there are various grassroots LoRa networks such as The Things Network and commercial networks such as Everynet (and Digital Catapult).

Adventures in Software Security Vulnerability Management (Lightning Presentations)

• Cathy Almond (Internet Systems Consortium)

A frank and unabashed review of some of the realities, challenges and difficult decisions that have to be made by an organisation responsible for the development and maintenance of several pieces of core Internet infrastructure software. If you were standing in their shoes, what would you do? (Audience participation and feedback positively encouraged).

Large BGP Communities

• David Freedman (Claranet)

Large BGP communities are a new standardisation that solves the problem of 32 bit ASN holders being unable to use standard (RFC1997) communities as others do.
