Keywords: reliability indicators, faultlessness, swarm of Unmanned Aerial Vehicles, topology, mathematical model, software, communication systems.

The paper analyses the existing methods of network communication with and within a group of unmanned aerial vehicles (UAVs) and the existing methods of assessing the reliability of the communication system with different UAV swarm topologies. The existing methods for assessing the reliability of the software part of a drone swarm and for estimating the failure rates of an individual UAV and a UAV swarm are analysed. A unified mathematical model for assessing the UAV swarm uptime indicators, including a combination of technical system, network communication system and software part, is presented. In addition, the results of the study of the influence of the network topology within the swarm on the reliability indicators of the swarm structure are presented. The results of dependence of reliability indicators and other characteristics with the help of computer modeling systems are presented.

REAL-TIME NETWORK TRAFFIC PREDICTION USING HYBRID ARIMA-GARCH MODELS

A.A. Grebenshchikova, The Bonch-Bruevich Saint-Petersburg State University of Telecommunications (SPbSUT), department of information and communication systems, assistance lecturer; grebenshikova.aa@sut.ru

Keywords: traffic prediction model, linear time series ARIMA mode, non-linear GARCH model, hybrid ARIMA-GARCH models, Box-Cox transformation.

Generalized autoregressive conditional heteroscedasticity (GARCH) models are often used in time series forecasting to control for data volatility. This study investigates the performance of hybridization of autoregressive integrated moving average (ARIMA) and GARCH models with Box-Cox transform for real-time network traffic analysis and forecasting. The Box-Cox transformation is used to normalize data, stabilize variance, and reduce heteroscedasticity. The orders of p and q in the ARIMA models were determined and estimated according to the Box Jenkins methodology. Model diagnostics were performed using the Ljung-Box Q-statistic, heteroscedasticity test, and analysis of the normality of the distribution of residuals of the ARIMA(p,d,q) and ARIMA(p,d,q)-GARCH(s,r) models.

INTELLIGENT CORE FOR 6G INTEGRATED NETWORK BASED ON SDN TO SUPPORT TELEPRESENCE APPLICATIONS

K.A. Kuznetsov, The Bonch-Bruevich Saint-Petersburg State University of Telecommunications, postgraduate; kuznetsov.sut@gmail.com

Keywords: SDN, SDN-multicontrollers, multiverse.

With the advent of telepresence services, a number of issues and constraints have arisen related to the transmission of all human sensations at a distance. The paper proposes a method to optimize the number of controllers in SDN networks. The experiment succeeded in reducing the number of controllers by 46%, at the same time increasing the utilization efficiency of each controller by 53%.

MODELING OF HOLOGRAPHIC TRAFFIC SERVICE PROCESSES IN A PUBLIC COMMUNICATION NETWORK

N.A. Demidov, The Bonch-Bruevich Saint-Petersburg State University of Telecommunications, postgraduate; deminickal@outlook.com.

Keywords: holographic traffic, simulation model, Pearson criterion, holographic copies, holographic type communication, HTC.

The article discusses the research results obtained on the basis of the developed simulation model. The basic steps for developing and confirming the hypothesis of this study are identified. A substantiation of the hypothesis is given that when a large number of holographic traffic flows are aggregated, we observe how the generated flow acquires the property of a simple flow. The data on packet arrival intervals, service times and delivery times obtained using simulation modeling are presented.

Keywords: firewall, iptables, eBPF, network traffic, Linux kernel.

The article examines the ways of processing and filtering traffic in high-load segments of mobile communication networks. An experimental verification of the effectiveness of the proposed method of processing and filtering network traffic in a network segmentation system has been performed. The features of processing and filtering network traffic in the Linux operating system have been identified, an experimental stand has been developed to test a modified method of filtering network traffic during network segmentation, and the results of experimental verification of the developed method have been obtained.

Keywords: fiber-optic transmission systems, dense wavelength division multiplexing, orthogonal frequency division multiplexing, flexible optical networks.

The article discusses the actual problems of using fiber-optic communication systems for efficient data transmission over long distances. Special attention is paid to the concept of optical superchannels, which combine several optical channels to increase transmission capacity and range. Theoretical and practical aspects of the implementation of optical superchannels are analyzed, including methods of multichannel signal generation, the use of optical precompensation of nonlinear effects and dispersion, as well as technologies for multiplexing orthogonal subcarrier channels. The prospects for the development of flexible optical networks in the direction of increasing productivity and optimizing the use of resources in modern telecommunication networks are considered.

Keywords: qualimetry, quality indicators, multiplicative quality assessment, complex criterion for system efficiency, service area, satellite mass, number of simultaneously served subscribers, broadband access speed, standard service life, communications satellite.

The expediency of introducing a comprehensive efficiency criterion at the stage of developing an innovative system of a high level of complexity, characterized by a significant number of components and requirements that are difficult to reconcile with each other, is shown. Without limiting generality, the introduction of such a criterion, based on the classical theory of qualimetry, is shown by the example of the creation of a national hybrid ground-space communication network. The presence of a comprehensive efficiency criterion allows independent development groups to optimize the parameters of the components of the national hybrid communications network while ensuring its efficiency and competitiveness as a whole.
