Abstract
In conditions of constantly increasing intensity of input traffic and increasing requirements for the quality of service of heterogeneous information in digital communication systems (DCS), significant overloads often arise in individual switching nodes (SM) and in entire segments of the system, which lead to an unacceptable decrease in the efficiency of information exchange ( AND ABOUT). In this case, a contradiction arises between the available channel-network resource of the DSS and the possibility of its effective use to provide information output with the required quality under conditions of high input traffic. Resolution of this contradiction is possible based on the implementation of a set of measures that ensure optimal distribution of information flows (routing) taking into account the capabilities of the DCS for transmitting and storing information. However, existing approaches, algorithms and implemented routing protocols are based on the use of local metric parameters, which do not allow to fully resolve the noted contradiction. Thus, it is urgent to search for new ways to effectively distribute information flows, allowing to improve a number of important characteristics of the information source (average time delay of a packet, number of losses, performance of the digital network). It should be noted that to implement these methods, it is necessary to use a generalized indicator of information efficiency, which at the network level would simultaneously characterize the capabilities of the central network for transmitting and storing information. Ultimately, solving this problem is of great scientific and practical importance for ensuring the timeliness and reliability of information transfer to the DCS.
