The article presents a hierarchical diagram of the network farm and a model of the network architecture levels. Protocols for disposal full mesh network topologies are considered. Modern data transfer protocol TRILL is presented. Its advantages are analysed in comparison with other possible protocols that may be used in the full-mesh topology. Empirical calculations of data routing based on a Dijkstra's algorithm and a patent formula of the TRILL protocol are given. Two monitoring systems of downloading data channels are described. The data obtained from 40G interfaces through each monitoring systems is presented, and their behaviour is analysed. The main result is that the discrepancy of experimental data with theoretical predictions to be equal to the weight balancing of the traffic when transmitting the batch information over the equivalent edges of the graph. It is shown that the distribution of the traffic over such routes is of arbitrary and inconsistent with the patent formula character. The conclusion analyses issues of the traffic behaviour under extreme conditions.
