The incumbent and IXPs in Sweden Kurt Erik Lindqvist CEO, Netnod MENOG7 - Istanbul 2010 Short Swedish IXP history •First IXP in Sweden was “D-GIX”, located at Royal Institute of Technology, founded in the early 1990s •From day 1 all (three) IP networks in Sweden present •D-GIX at one time was the largest IXP in Europe, and handled a lot of the European traffic •D-GIX turned into Netnod in 1996 Why did we peer in Europe? •80% of traffic was destined for the US •European operators wanted to avoid paying transit to US companies •And not to send the traffic across the atlantic •Also wanted to avoid paying expensive international half-circuits Why did the incumbent peer? •To not peer was never an option •Partly because you had to be part of the IX to be part of the Internet community •Was seen as an important sales point / business point •Peering policy was in place from the beginning Sweden’s IXPs Luleå Sundsvall Stockholm Gothenburg Malmö Peering policy •You had to be of similar size •Traffic •Geographical coVerage •Hot potato routing •You had to connect to all Netnod IXes Reasoning •From the beginning there wasn’t that many pan-national operators •If you had invested in a build-out you had roughly the same backbone cost as the incumbent •With hot-potato routing you loaded the transport cost on the other network for their customers Advantages •Led to inVestments in national networks •As “eVeryone” peered, service differentiation was focused on •InnoVatiVe services •Latency •As interconnects was used as service differentiator, all networks had to make sure they had enough peering bandwidth Why don’t/didn’t other incumbents peer? •Perception that you are loosing customers / revenue •But in the change to a deregulated market the preVious monopoly can only loose market share •Belief that not peering will be a service differentiator •But in reality you are proViding a second class service to your competitors Modern times •The incumbent split the network into different ASes •TeliaSonera started TeliaSonera International carrier as a transit supplier •But the national AS still peers at Netnod Questions?.
