The paper considers the issues of traffic balancing in computer networks using Software-Defined Networking (SDN) technology. The expediency of load balancing in SDN networks on the basis of multipath routing is substantiated. The criterion of path selection is proposed, which allows to provide the maximum possible uniform loading of channels.
The method of traffic balancing is proposed, which due to the centralised way of route information formation in the SDN controller and the use of multipath routing method allows to increase the efficiency of dynamic traffic reconfiguration procedure. Formation of routing information is carried out using a modified distance vector routing algorithm. This algorithm allows simultaneously with the formation of a given route to form paths from all intermediate nodes to the final node. The method of centralised formation of routing information is proposed, which allows to exclude repeated formation of routing information for previously formed sections of the route.
