European Internet exchange update slides
I presented a talk on recent European Internet exchange news [download] with Mike Hughes from the LINX last week at UKNOF. Many of the attendees run networks that do not peer publicly, so it was a pleasure to explain the impact that European IXPs have on member traffic. We also then gave a perspective on peering in London.
Many of the statistics came from Serge at Euro-IX who did the leg work for the raw figures.
The highlight points of the talk were
- Euro-IX identify 103 exchanges in Europe, in 31 countries. (3 in 1993)
- 8 Exchanges in the UK (was 9 until BT’s UK6x closed)
- At the end of 2007 networks publicly peered 1.215Tbit/sec at peak.
- More public peering in EU than US (but it’s cheaper to peer in EU thanks to lower x-connect fees, and cheap ubiquitous mutual exchanges)
- London is #1 for network reach - 601 networks peer publicly, 415 peer exclusively in the UK.
- 22% of LINX members peer exclusively at LINX, 31% of LONAP members peer exclusively at LONAP.
- 577 networks peer at more than one IXP, and one network (Colt) is present at 19 exchanges!
- Last year the good weather in April caused an additional summer-time traffic dips in Europe, in addition to the regular dip in July/August
There’s other stuff in the slides too, such as the usual traffic updates for various major exchanges in Europe.
