Abstract. The authors propose a technique for the solution of the packing optimization problem to obtain the initial data necessary for the construction of mathematical models of perspective development of nodes of multicommodity communication networks with discrete flows. The results of numerical modeling of the solution on a specific example for five stages of network development are given at forecasting the increase in total flows in nodes. It is shown that in case of node overload because of short-term fluctuations of flows or total refuse of several nodes, centralized solution of the packing optimization problem for the whole network can always be used for operative redistribution of flows.

Keywords: multicommodity networks, discrete small-batch flows, model of perspective development.
