Structural and functional directions of complex network systems research are considered. The network system is defined as a complex network where flows occur. The classification of network systems is carried out on the basis of continuity and the level of orderliness of flows. Flow characteristics of network systems are introduced along with the structural characteristics of complex networks. The problem of critical loading of network components is studied. Problems of dimension and adequacy of models of network systems are considered. It is shown how the system's flow characteristics allow us to identify and exclude fictitious nodes and links from its structure and determine the hidden elements of the system. It was investigated how on the basis of the analysis of flows processes in the system the structure of scale-free networks changed not only during the growth stage, but also during the whole life cycle of the corresponding network system. The problem of isolated zones of network systems is considered and the algorithm is proposed for finding alternative ways for flows in order to bypass inaccessible components of the network.
