The technologies of perspective satellite networks suggest their use to form an end-to-end information exchange, regardless of whether the network is terrestrial or non-terrestrial. In this case, the quality of service must be ensured throughout the reception/transmission path. This is directly related to the prospects of using satellite networks in the field of the Internet of Things, for example, to control various unmanned devices. Characteristics of the quality of service such as delay time and the loss probability directly affect the performance of tasks by such unmanned devices. The hybrid satellite networks are also supposed to be used to serve subscribers of 5G/6G networks, but this will require the placement of multi-satellite groupings in low and very low Earth orbits.

Thus, promising hybrid satellite networks use a variety of orbits that host a large number of spacecraft (with intersatellite lines), providing heterogeneous communication services, including to subscribers of terrestrial mobile networks. In order to prevent network congestion and maintain the given quality of service in a hybrid network, it is necessary to ensure the functioning of conformed end-to-end quality assurance functions.

The main purpose of this work is to provide the basic provisions of the concept of the quality of service in hybrid orbital-terrestrial networks. The main results are the multilevel approach, distributed management, topology-invariant method and wide using software-defined systems. The multi-level approach is based on a multi-agent organization of service quality provision with a hierarchy both by type of orbit and by functional purpose. As a topology-invariant method, it is proposed to use tensor analysis of networks, which provides the possibility of taking into account the process-structural interaction of information flows, the distribution of which across the network affects the quality of service. Software-defined systems allow a flexible approach to the distribution of functions and resources in a multi-agent system by using software-defined networks and software-defined radio.

The main results of this work can be used in the formulation of requirements for systems and complexes of perspective hybrid satellite orbital-terrestrial networks. Further, it will be used for multi-agent distributed system of quality of service provision for perspective hybrid satellite-terrestrial networks.
