In this paper, in order to increase the scalability of the communication network, a three-level method of hierarchical coordination routing in multi-area network is proposed, which is based on the principle of goal coordination. The method is based on the decomposition representation of the flow-based routing model and it includes three levels of the calculation hierarchy: at the zero level, the routing variables are calculated by the border routers of each area; at the first level, coordination of zero-level decisions is carried out to prevent congestion of communication links in each individual area, and the task of the second-level coordinator is to ensure inter-area interaction.
