Cloudfpare claims that in the EU there are mostly two ways for them and Netflix to reach a user
1. Connect to a big exchange where every Telco is connected
2. Directly peer with the Telco at much higher prices
The thing I do not understand is why do Telcos accept lower prices from the exchange.
Is connectivity sold auction-, style? Could t-mobile decide to charge double [1] for use of its infrastructure?
Whatever it happening it is unclear to me why they happen to accept lower prices from one entry point and not another. Are these connections materially different?
[0] end user is well defined in the case of someone whatching Netflix.
[1] by net neutrality they cannot charge Netflix more, but they can charge everyone more.
They are forced to, if they did not, their users would complain that the internet does not work.

Though I don't think this reflects the rank of overall importance to settlement-free transit, since a single settlement-free agreement with AT&T or Deutsche Telekom or China Telecom, etc., would be worth more then hundreds of agreements with smaller regional players.
Probably the importance of IXPs also follow a power-law distribution, with the top 100 exchanges combined seeing more traffic then the next 1000 combined.
