    • 10:30 - 10:55 LTE as a Video Distribution Network 25'
      To effectively deal with the forecast tsunami of mobile video, mobile networks need to evolve from communications networks to video distribution networks. There are technology disjoints in end to end mobile video delivery, which drives a need for increased communication and knowledge share between all parties in the chain. Industry-wide engagement will create a mobile video ecosystem, improve customer experience, encourage innovation and ensure the long term viability of the mobile video industry.

    • 10:55 - 11:25 Spring Forward(ing) - Evolving IP/MPLS Networks with Segment Routing 30'
      Segment Routing is a new approach to implementing IP/MPLS networks proposed within the IETF. It aims to simplify the control plane implementation of existing MPLS networks, as well as to address the challenge of providing scalable source routing capabilities to MPLS - both for service provision, traffic engineering and fast re-route. This talk aims to provide an introduction to the motivations for SR, the fundamentals of the architecture, and some example use cases -- touching upon the potential direction that this approach could point to for IP/MPLS networks in the future.

    • 11:35 - 11:50 Morning Coffee Break
    • 11:50 - 12:20 No Help Desk for Light Switches 30'
      Increasing numbers of Internet-connected fridges and grandparents, together with cloud-based service delivery hysteria, are pushing availability requirements for web-accessible services through the roof. Subscribers are less interested in the reasons for failure, and are largely disinclined to try and call anybody for help (who would they call?) Service unavailability leads to lost subscribers, lost momentum and fear of lost investment and business failure. Being up is important.
      Small, upstart web properties have options for outsourcing pieces of their infrastructure and operations to get a leg up on network and platform availability. With escalating availability requirements and a desire to be able to serve hot markets opportunistically, we consider how deep we can dig this particular rabbit-hole. We describe some of our thinking about how to scale our current service delivery platform from 20 sites globally to something much, much, much (much) bigger. We consider logistics, security, provisioning, manageability, monitoring and measurement, and begin to paint a picture of DNS service at a scale not previously seen on the Internet.

    • 12:20 - 12:45 New exposure for DNS infrastructure 25'
      DNS amplification attacks have evolved considerably and now regularly stress DNS resolvers, networks, and operations teams.  Attackers can easily generate gigabits of traffic with modest skills and resources by targeting home gateways with open DNS proxies.  
      Tens of millions of these devices are scattered across the internet and Best Common Practices such as preventing address spoofing and restricting IP ranges that can access provider resolvers do not deter these attacks.  
      Since vulnerable home gateways won't be updated anytime soon this presentation will cover other ways to identify and mitigate attacks without impacting legitimate DNS traffic.

    • 14:00 - 14:30 Comcast's IPv6 Deployment 30'
      The beginning of Comcast's IPv6 program dates back to 2005, in 2013 the cable operator grew to become the world's largest IPv6 deployment.  Join us in this session to learn more about the operator's IPv6 journey and how Comcast has and will continue to leverage IPv6 to support growth and fuel innovation.  During this session you will also hear what Comcast has on tap for the next generation consumer services specifically around IP enabled voice, video, and data.  Finally, as part of this session you will also learn more about Comcast's pioneering work advancing the state of cable home networks and how the same is foundational and a key enabler for other advancements in next generation home networking.

    • 14:30 - 15:00 Routing IPv6 in the Homenet 30'
      As more and more ISPs provide IPv6 to residential subscribers, the IETF Homenet Working Group has been aiming to to “raise the bar” for networking in the home, allowing for global, end to end, IP connectivity not just to the home, but within the home as well. Mark will talk about what has been going on in the IETF as well as Open Standards development in order improve our home network experience and set the stage for future innovation.

    • 15:00 - 15:30 Janet6: Building a national 100GE network. 30'
      Over the past year, Janet, which serves education and research in the UK, has been refreshed with a new dark fibre infrastructure.
      At the start of Janet’s 30th anniversary year, this presentation will describe some of the design decisions that went into building Janet6, some of the lessons we learned whilst we were building it, and where we’re looking to go from here.

    • 15:30 - 16:00 FTTH for the last 5% 30'
      B4RN is building an FTTH network in the deeply rural areas around the Lune Valley and forest of Bowland AONB. The area covers 420Km2 but contains only 3500 properties. The project will deliver PtP 1Gbs symmetrical to every property within the 23 parishes included in the scheme. With an average dig distance of >200m per property this would normally be considered totally uneconomic for any telecoms company to do yet alone at a monthly cost of £30 which is what B4RN charges.
      However B4RN has adopted two techniques to make it possible. Firstly the fibre is laid cross country across private land with the land owners granting free wayleaves. Narrow bore 16mm duct is used with mini fibre cables then blown in using 15bar compressors. Counts of up to 192f are being installed with blow distances of up to 2Km achieved. Secondly the funding is coming from within the community via a shares issue by B4RN inviting people to invest in the project. Investment can be via cash or sweat with those having the cash opting to put money in whilst those with the time and ability invest their sweat digging ducts and installing the network components. 
      Speaker: Prof. Barry Forde (B4RN)

    • 16:10 - 16:30 Afternoon Coffee Break
    • 16:30 - 17:00 Panel: "Really Regional?" - the challenges of a non-London centred network 30'
      How hard is it to build a network which is independent of London?
      Can you take an existing network with a heavy London concentration and turn it into something more distributed? What about being regional from scratch?
      What might it look like to the rest of the UK if a significant network failure were to hit London?
      New regional connectivity initiatives in the UK are currently proving to be areas of significant activity, enabled by a mixture of community activity, new entrants into the colo market and a desire to deliver bandwidth more locally as volumes increase as a result of highspeed broadband rollout.
      The panellists hope to discuss such questions and more.

    • 17:00 - 17:25 Ansible for configuration management 25'
      Ansible is a new configuration and system management tool written in python. It has quite a large library of modules to manage various aspects of a Linux system, and new modules are being added all the time. It's also trivial to write one's own custom modules using a simple API.
      Ansible differs from tools like cfengine and puppet in one major area: it's push-based. In other words, there's no central server for nodes to connect to. Instead, you can connect to all managed nodes over just regular SSH, and perform system reconfiguration and enforce state.
      However, if one wants to use a cfengine or puppet-like model with ansible, it is also possible, using ansible's local mode. This is how we're using it at the RIPE NCC, and my presentation will talk more about this, along with some of the ideas we've developed.

    • 17:25 - 17:50 NICC Standards 25'
      NICC Standards is the design authority for the UK telecoms network.  Its role is to agree interoperability standards between the UK fixed and mobile telecoms providers, including interconnection and access.  NICC’s output is used by Government and Ofcom to inform their policy formulation.  This presentation will give a summary of NICC’s history, its current work plan, its current membership, and how to get involved to shape future standards.
