A given work proposes a method of balanced shared explicit reservation for multicast routing in communication network. A mathematical model for multicast routing supporting shared explicit reservation of link resource was presented, which is introduced by linear expressions that are responsible for ensuring the connectivity of the calculated multicast routes, as well as the absence of loops in them. The analysis of the solutions for the multicast routing tasks and the shared explicit reservation of network resources using the proposed model for different network structures, flow characteristics and the used optimality criteria is conducted. The use of the proposed model ensured the improvement of the obtained results on average by 45-65% compared to the distributed (uncoordinated) solution of multicast routing tasks and reservation of link resources used in modern network protocols. According on the results of the conducted studies it is recommended to implement the complex optimality criterion, the use of which is most effective from the point of view of both balanced use of the network resource and in terms of ensuring the maximum productivity of the network as a whole.
