2. Background In the peering track at NANOG62 Sylvie LaPerrière presented a comparison between population density and existence of an IXP Authors thought we should try the same for Europe, but also try and do further analysis – The latter turned out to be a bit harder… European IXP Topography Project213/05/2015

3. Scope 1.Analyze IXP proximity to major population centres 2.Develop classification system for IXPs 3.Combine 1 & 2 into a guide for European IXP scene 4.Draw conclusions and try and predict future market European IXP Topography Project313/05/2015

4. IXPs in Europe European IXP Topography Project413/05/2015

5. IXP Classification 1.Membership-based IXPs (i.e. where the members own the IXP) 2.Other types of not-for-profit IXPs (e.g. those owned by trusts such as Netnod, or other industry associations, such as DE-CIX or JINX) 3.IXPs hosted in academic institutions or academic service organisations (such as national academic or research networks) 4.IXPs operated by commercial data centre organisations 5.A commercially owned IXP (such as ECIX) 6.Joint ventures of some combination of the above (a fairly rare case) European IXP Topography Project513/05/2015

16. Comparison to US study All but one of the 19 largest CSAs in the US have an IXP – 11 are major peering hubs The smallest of the 19 would be the 11 th largest in Europe Europe seems to have a denser mesh of IXPs while lacking IXPs in more large population centers European IXP Topography Project1613/05/2015
