The study is devoted to the creation of simplified simulation models of packet switching networks, which are currently actively used on Earth and implemented in satellite systems. Further development of a simplified simulation model of a load-open packet switching network is proposed. The main provisions of building a simulation model are the distribution of the node storage at the filling level, determining the number of non-empty storage levels as a node state, modeling the node load state as a superposition of two, connected through the node states, propagation and death processes (the first process is caused by the network exchange of load with users, and the other - by the passage of transit load through the network node). It is proposed to increase the adequacy of the model by developing the approach previously used for a load-closed packet switching network, according to which the transit load output is simulated for most nodes taking into account their operation with maximum throughput, and an adjustment correction is introduced for a group of lightly loaded nodes.
