11:10 → 11:35 Whitespace Networks in the UK

Whitespace spectrum is a new way of offering large amounts of spectrum where the owner currently doesn’t or can’t use it. Opportunistic spectrum sharing allows swathes of TV and other spectrum currently lying unused to be accessed by users on a geographical and temporary basis (eg. in a specific location for a couple of minutes or months) by using coordination databases rather than auctions and long-term ownership. This spectrum has characteristics ideal for the Internet of Things and wireless sensor networks - long range, low power, good penetration, good bandwidth. For the UK, access to spectrum by entites other than telcos willing to bid billions of pounds is an important step in our development as a country and society. A regulator taking steps to empower the individual is surprising and encouraging, so let’s use it before it’s given away.

16:00 → 16:25 Observing Limited Visibility Prefixes in the Wild

Advertising a prefix is only the first step towards achieving global reachability. However, filters and policies may not mean that an advertised prefix is reachable from everywhere on the Internet. We have build a tool, that looks at publicly available data and checks the global reachability of your prefixes. The output from our studies are available at visibility.it.uc3m.es. Such limited visibility can have many different reasons, but we had some initial talks to operators and discovered many misconfiguration problem. We would like to turn this tool into a useful "BGP policy verification" system. In this talk we report on our findings of analysing many month of global routing table data, we find that there are about 100.000 prefixes that show limited visibility and about 3.000 prefixes which do not have any less specific prefix (e.g., which do not provide any connectivity at all).

16:25 → 16:50 Beating Bufferbloat with FQ_Codel

Most of the excitement over reducing latency under load on edge networks has been focused on the combination of the Flow Queuing + Codel algorithms now in the Linux kernel, called fq_codel. This talk goes into how, why, and where that works, and the sorts of network traffic that can and cannot be optimized. It leverages new studies from cablelabs and others on the prospect of deploying the new AQMs in devices such cable head ends, dslams, cable modems and home gateways.

16:50 → 17:15 Adaptive Bit Rate video delivery

Internet based delivery of video services across non-multicast enabled networks is currently led by the likes of Apple, Microsoft, Adobe. Each have their own carriage system for the "chuncks" of data delivering "Adaptive BitRate" services which causes some providers to have to encode up to 120 versions of a single source. This presentation will discuss how MPEG-DASH, a recent standard that is aimed at unifying those different models under a single common scheme combined with the standardisation of the new H.265/HEVC video codec, will continue to transform how video services are streamed across IP networks.

Speaker: Mr Thomas Kernen (Cisco)

17:15 → 17:40 Akamai and ISPs

UKNOF invited me to explain a little bit about how Akamai works and how Akamai and ISPs interact. This talk is designed to impart a very high level understanding on the Akamai system and give ISPs some idea of how Akamai works with an ISP to deliver content to end users.
