Deliberate destructive electromagnetic influences formed on the basis of existing technical means are an effective type of modern radio-electronic information and technical influences on information and communication networks. The radio-electronic material basis of information communication networks is potentially vulnerable to the influence of means of radio-electronic suppression. The need to ensure the high-quality functioning of modern information and communication networks under the conditions of intentional electromagnetic destructive effects requires correct and timely management decisions from the network management system to prevent undesirable consequences, which necessitates the creation of more advanced management methods. The purpose of the publication is to consider the vulnerabilities of modern information and communication networks from intentional destructive electromagnetic influences, which is understood as the deliberate creation of a powerful electromagnetic influence on electronic and electrical systems for criminal or terrorist purposes in order to disrupt their functioning. The effects manifested at different levels of information communication network functioning as a result of intentional destructive electromagnetic influences are considered. Based on the results of the research, the following conclusions can be drawn: intentional destructive electromagnetic influences are aimed at destroying information flows circulating between network elements; decrease in the speed of information exchange between elements of the control system, which significantly increases the duration of the control cycle and, as a result, reduces the efficiency of network management; ensuring sufficiently massive and long-term failure of network technical means; existing systems and methods of radio electronic suppression are focused on suppressing only individual channels of the network by disrupting the functioning of communication protocols at the physical and channel levels of the OSI model; in the future, there is a threat of transition to the use of individual elements of the radio segment of the information communication network as a kind of «entry points» for radio-electronic information and technical influences, which will disrupt the network processes of information transmission and spread their destabilizing influence on the entire network, including its wire segment. In the article presented to the readers, only some aspects of the researched topic are highlighted. Currently, the authors continue active research work in this subject area.

At present, to precisely ensure the routine use of intelligent vehicles' communication network, accurate data transmission is of great importance, which can also, to some extent, improve the network failure management and maintenance of smart cars, thus affecting the intellectual analysis ability of intelligent cars. Therefore, it is very necessary to perform real-time monitoring of abnormal data in the everyday use of smart cars and their regular operation. Based on the detection of anomalous data of intelligent vehicles, an instantaneous frequency estimation method of signals transmitted by a communication network is proposed in this paper. In terms of abnormal data detection, after the time-frequency decomposition of the output signal of the collected communication network, the collected anomalous data can be detected by extraction, and then the detected and captured abnormal data is filtered to finally complete the characteristic extraction of the strange frequency of the abnormal data.

The functioning of modern information and communication networks is impossible without data processing. With the emergence of new network services, the amount of information that needs to be processed increases, while the requirements to the data processing quality become more and more stringent. Therefore, the problem of designing and maintaining a scalable data processing system with a flexible quality of service management is becoming more and more important for a network operator. Such data processing systems have a complex internal structure with many interrelated parameters, which makes them difficult to analyze, manage, and expand. This study proposes to use an ontological model to store, represent, and manipulate the information in the operator’s data processing system. The ontological model allows to structure and systematize the data of an information processing system, and transparently reflects the relationships between the parameters of the system to simplify its analysis and scaling. The proposed ontology of a data processing system consists of three related subsystems. The paper describes the proposed ontological model and additionally analyzes the sources of information that needs to be processed in the information and communication network.

Traditional queueing models for traffic flows in communications networks are based on Markovian assumptions. However, recent studies within Bellcore of large sets of real-time network traffic measurements have revealed that traffic in computer and emerging high-speed networks has features that are more accurately and more efficiently described in terms of fractal models, rather than traditional Markovian models. This paper briefly reviews these measurement studies, and motivates the application of fractals to describe and analyze traffic flows in modern communications networks.

Modern communication networks are expected to have hundreds or thousands of network nodes to which thousands of users are connected. Neural networks can contribute to this emerging new telecommunication infrastructure by providing fast, flexible, adaptive, and intelligent control. This article discusses the neural networks used for solving various control problems in high-speed communication networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

In modern communication networks it is interesting not only to know how fast packets can travel in the network, another parameter object of study is the number of information packets at each node of the network at time t. Some models of traffic in imperfect communication Networks has been proposed for the Internet, important features such as delay in transmission and packet lost and congestion at the nodes must be taken in consideration by the model. Some imperfect traffic models based on fractional calculus have been proposed. This works present some computer simulations of internet traffic and comprare the results with the ones provided by the fractional calculus models.

The new 5G network is to come very soon. Still many challenges have to be overcome, severe problems to be solved. One of these challenges is to reduce the power consumption drastically compared to existing networks. With a short literature review, a few examples of how power consumption in modern communication networks could be decreased, while data through-put and the quality of service could be increased, are discussed briefly in the following sections.

Purpose: to develop scientific and technical proposals and requirements for building sources of synchrosignals and messages of a single time for the integrated system of synchronization and delivery of the time scale depending on the requirements in frequency-time support signals and the current communication chain architecture in the framework of solving a unified synchronization system in phase time and the frequency in large territorially distributed and industrial technological systems. Methods: the applied research methods include the fundamental provisions of the theory of constructing synchronization systems, as well as infocommunication systems and networks. Results: a functional model of a united source of the integrated system of synchronization and delivery of the time scale, which includes a complete set of elements to perform the functions of synchronization and delivery of single-time signals in existing and promising complex heterogeneous networks with various architecture and heterogeneous equipment that differs from the existing fully taking into account the existing ones in Currently, technologies for delivery of single time and frequency signals, both on the basis of switching packages and on the basis of switching of channels. The proposed functional model of the united source of the integrated system of synchronization and delivery of the time scale will allow to reasonably approach the design of the means of transmitting and delivering single time and frequency signals to various and heterogeneous communication networks, taking into account all the needs for frequency-time support signals and limiting existing communication networks. Practical significance: the use of sources of single-time and frequency signals, which are based on the proposed functional model, will ensure a flexible infrastructure to ensure the unity of the unity of the unified time and clock network synchronization necessary for the correct functioning of communication equipment; Satisfy the requirements of synchronization signals and uniform messages for promising and existing consumers as much as possible; ensure the possibility of a phased transition of the construction of communication networks from the technologies of the channels to the technology of switching packages due to flexibility in the use of routes and transmission systems necessary for the spread of synchrosignals and uniform messages.

As the demand for calls by subscribers in communication networks increases, it is necessary to have sufficient equipment or a high‐degree of control over the communication network to make immediate connection of the calls to the desired parties by subscribers at any time they desire. However, economically, it is impossible in large‐scale, modern communication networks to provide enough equipment for all traffic fluctuations. In this paper, a measure of “abnormality” representing the degree of the fluctuations of the subscribers' demand is used to ensure the connection of the calls by limiting all traffic fluctuations below a specified abnormality. First, for the traffic pattern representing the subscribers' demand, we derive a theoretical formula and an approximate calculation method for the traffic intensity which the communication network must actually carry, taking into consideration the number of subscribers.Then we calculate the traffic intensity which each equipment must carry in a communication network using a relatively simple method of route selection. We present a method for obtaining a maximum value for the traffic pattern below a specified abnormality. It is adequate enough to provide a sufficient number of equipment for the traffic intensity to be carried. It may be possible by this design method to have a very efficient reinforcement of the equipment for traffic fluctuations by a limited equipment investment.

Recent environmental changes have shown the world the importance of sustainable development and these changes demand concrete solutions. The Smart Grid solution is recognized as a key technology to cope with these challenges, not just concerning the environmental impact of greenhouse gases but also regarding the increasing electric demand. Smart Grid is a combination of two networks, the first being the electrical transmission and distribution network, while the other is the modern data communication network. The Smart Grid communication network can be divided into three parts, HAN (Home Area Network), NAN (Neighborhood Area Network), and WAN (Wide Area Network). IEEE 802.15.4 and IEEE 802.11 MAC protocols, which are based on the CSMA/CA mechanism, are assumed to be the candidates for the MAC layer of HAN. However, it has latency and energy efficiency problems. In this paper, we have redesigned a tree based TDMA MAC protocol which can be applied in Smart Grid HAN. From the experiments, we verify the performance of our proposed protocol with respect to the network latency, high packet transmission rate and energy efficiency.

In this study, based on the concept of a mobile network computer, the author points out that a modern mobile communication network should be referred to as a mobile computer network and a modern mobile communication terminal should be referred to as a "mobile network computer", rather than a "mobile phone" or a "mobile computer" etc. Also, an introduction to the integration approach of mobile communication and computer networks is provided, including technology integration, business integration, network integration, and IMS technology in terms of several aspects, for the purpose of providing people with opportunity to learn more about mobile computer networks, and thereby better understand the concept of a mobile network computer, in order to popularize the concept of mobile network computers throughout the world. In the computer and internet age, network and mobile network computers may be the main terminals of fixed and mobile networks. Therefore, the author of this study not only illuminates the development of mobile network computers, but also draws the outline of a complete picture of the information society in terms of network and mobile network computers. Doing so enables people to have a clearer understanding of information society. It should be noted that in this study both the "mobile network computer" and "mobile computer network" are discussed. These are two distinct types of concepts, so please pay careful attention to avoid confusion.

&lt;p&gt;In meeting the diverse and occasionally conflicting quality of service (QoS) requirements associated with modern communication networks, 5G technology has emerged as a pivotal player. In its architecture, 5G has adopted network function virtualization (NFV) and cloud-based approaches, aiming to simplify network and service deployment, operational processes, and management. The convergence of software defined networking (SDN) and NFV offers an effective solution, enabling scalable and high-performance 5G networks. However, this integration poses critical challenges, with the placement of SDN controllers being a central concern due to its significant impact on network performance, covering aspects such as latency, costs, and energy efficiency. This challenge is known as the controller placement problem (CPP). The central theme of this paper revolves around the intricate relationship between 5G core networks, virtualization technology, and the pressing concern of SDN controller placement, underscoring its significance in the modern networking landscape. We provide a survey of recent methodologies aimed at solving the CPP within the realm of SDN, with a particular focus on resiliency and high availability.&lt;/p&gt;
