THE METHOD OF SEQUENTIAL APPROXIMATIONS FOR FINDING THE OPTIMUM DISTRIBUTION OF MEASURED INFORMATION FLOWS IN THE NETWORK OF GROUND STATIONS OF SATELLITE RADIO NAVIGATION SYSTEMS

Abstract

In the conditions of network operation, when the time of processing measurement signals in the switching node takes a certain amount of time, and the importance of information has different values, there is a need to organize queues of requests for information service. The main goal of such an organization is to reduce the loss of information in the network during transmission under the conditions of using transit routes. The dynamic restructuring of the queue at the nodes, in turn, ensures a reduction in the loss of applications due to their "aging". The structure of the dynamic flow management system [...] provides a special place in the switching subsystem for the control system, which controls the measurement, collection, processing and further movement of traffic in networks, the distribution of network switching resources in accordance with the set priorities of information transmission. It is obvious that the use of systems for dynamic management of measurement information flows as part of the switching structure will ensure the necessary quality of network functioning, prompt response to low-inertia situations in real time. Dynamic management of the distribution of information flows can be carried out both by managing the network structure by changing the capacity of channel bundles, or by redistributing network channels when changing the information interactions between individual pairs of switching nodes, and by managing the flow transmission paths without changing the network structure. It is obvious that the second method is both economically and hardware more profitable, since changes to the network structure are minimal.
