In communication networks, routing decisions are based on routing policies. There is no solution for the problem when we want to determine the policies by the observation of the network. However by using the mathematical models of routing policies, we will be able to create a simulator which helps discover this policies.
In this thesis my goal is to build a simulation framework that can determine the routing policies of real large-scale networks. The simulation framework uses the mathematical models of the routing policies. I will define a measuring system to compare the simulation results. I will use the simulator to examine the policies behind the route-defining decisions of the largest airlines.
