The choice of the structure of the internet traffic exchange network is an urgent task for countries located with large areas. A mathematical model of this network with two Internet exchange points (IXes) in the form of a queuing network has been developed and analyzed. The proposed model, which, if necessary, can be generalized to the case of an arbitrary number of IXes, allows calculating the main characteristics of the network, determining its optimal parameters and analyzing alternative construction options: average round-trip delay (RTD), channel capacity, calculate the performance of traffic exchange nodes under reliability and cost constraints, and topology selection for the traffic exchange network, considering the main parameters. The results of calculations for Internet traffic exchange networks with uniform and significantly uneven loading of network channels are presented. An Internet traffic exchange network with several IXes can provide a lower delay, higher availability, and lower costs for implementation and commercial operation. In this case, a network with several IXes will enable the owners of these nodes and regional telecom operators to improve service and gain economic benefits.
