DNS-based DDoS: Evolving Threat (Main Session)
- Ralf Weber (Nominum)
10:25 - 10:55
Room: Charter 1, 2 & 3 Very recent changes in the intensity, duration and targets suggest continuing experimentation by attackers at the expense of DNS infrastructure worldwide. Drawing upon high resolution worldwide resolver data this presentation will cover changes in attack vectors. Tests of mitigation techniques will also be presented, comparing and contrasting alternatives.

Tales of the unexpected revisited - handling unusual DNS client behaviour (the sequel) (Lightning Talks)
- Cathy Almond (Internet Systems Consortium)
10:55 - 11:20
Room: Charter 1, 2 & 3 Experiences of unusual DNS query patterns have been the focus of many recent talks that have examined the sources, targets and intent of this traffic, as well as the impact seen by authoritative servers and resolvers alike. Last year, ISC proposed and then started trialling experimental recursive client rate limiting techniques in BIND, with the intent of limiting the impact of this unwanted traffic on both servers and DNS clients alike. This talk briefly recaps some of the problems that can be encountered and then presents a review of the effectiveness of the techniques that were introduced, along with results from live production environments.

Grant money doesn't buy you happiness (Lightning Talks)
- Nat Morris (UKNOF/Esgob)
11:50 - 12:10
Room: Charter 1, 2 & 3 Back in October 2013 a group of interested individuals met at the Millenium Center in Cardiff to discuss the possibility of starting a Welsh IXP. Plans developed and LINX along with Cardiff City Council and the DCMS discussed opening an exchange within BT Stadium House. Independently of LINX, the local city council offered grants of up to 20k to connect to the exchange, this was intended to cover the costs of routers and associated PoP build out fees. Currently only 2 of the 21 IXCardiff members ASNs existed prior to the grant being announced. This talk will highlight: - traffic levels - number of ASNs behind the same 2 local transit providers - prefixes shared on the same LIR - members with the same registered limited companies directors - how throwing money at a problem does not fix it 15 minutes, this is with my ESGOB Ltd hat on.
12:10 On Factors Affecting the Usage and Adoption of a Nation-wide TV Streaming Service - Dmytro Karamshuk (King's College London)
On Factors Affecting the Usage and Adoption of a Nation-wide TV Streaming Service (Lightning Talks)
- Dmytro Karamshuk (King's College London)
12:10 - 12:25
Room: Charter 1, 2 & 3 Using nine months of access logs comprising 1.9 Billion sessions to BBC iPlayer, we survey the UK ISP ecosystem to understand the factors affecting adoption and usage of a high bandwidth TV streaming application across different providers. We find evidence that connection speeds are important and that external events can have a huge impact for live TV usage. Then, through a temporal analysis of the access logs, we demonstrate that data usage caps imposed by mobile ISPs significantly affect usage patterns, and look for solutions. We show that product bundle discounts with a related fixed-line ISP, a strategy already employed by some mobile providers, can better support user needs and capture a bigger share of accesses. We observe that users regularly split their sessions between mobile and fixed-line connections, suggesting a straightforward strategy for offloading by speculatively pre-fetching content from a fixed-line ISP before access on mobile devices.

Counting the world with skewed samples: how APNIC adusts its measurements (Main Session)
- George Michaelson (APNIC)
16:00 - 16:30
Room: Charter 1, 2 & 3 APNIC has been conducting a long lived (5 year) measurement activity using google ads and javascript placements worldwide. We collect over 700,000 experiments a day from end users. The sampling is random, but has placement bias. So, we've developed methods of adjusting for this using world population stats. A side effect of this is that we may now have one of the only public insights into relative market share in the ISP community worldwide, and inside each economy.

FFO - fracking fiber optic (Main Session)
- Thomas Weible (Flexoptix GmbH)
16:30 - 17:00
Room: Charter 1, 2 & 3 LC plugs are not the only ones now that we have QSFP+. Should you use MPO or MTP. What about ST, LC, SC, E2000 or the new LC Uniboot plugs ? What are the compromises and benefits of each solution. Did you know that polarity in optical MPO matters ? And why the polish of a plug can cause headaches during on-site installation. Thomas will give an overview of the connectors and fibre options in the datacentre now we have 40G and 100G as standards. Especially for parallel transmission applications you should consider rethinking your wiring if you don’t want to get stuck in troubleshooting your links. Finally some practical examples of broken optical components after and during field installation – real cases which happen every day even in 2015 when fibre optic is a commodity. Duration: 25-30 minutes
