The modern protocols of dynamic routing, the principle of their functioning and methods of assigning a link metric are considered, it is determined that most of them are one-way, choose one route with a minimum metric or carry out balancing between routes with the same metric. As a result, the network operation in this way causes the maximum use of the best or alternative path found, their overload, while other nodes (resources) of the network are not involved in the transmission of traffic. Since such a decision is necessary for all oneway protocols, the introduction of changes directly to the protocol itself is not rational. The solution to this problem may be due to structural changes in the network, namely the modification of the routing process, combining the best features of distributed and centralized routing methods. Routing protocols continue to work according to the distributed principle - each router independently builds routing tables based on information received from other routers. After the implementation of the centralized router controller, all routers will periodically receive information about their functional state. When required by the controller, the SNMP changes the router's parameters with the subsequent change of the routing tables, and the control module conducts the analysis and calculations to initiate the change
