Texte intégralRésumé :
The increase in the number of cases of failure of information and telecommunication networks due to cyber attacks determines the need to protect them from this type of attacks. The issue of increasing cyber security in the conditions of conducting operations by groups of troops (forces) is very important. Due to the armed conflict in the East of Ukraine, the military-political instability in the Middle East, the struggle for influence on world financial and energy flows, the global military-political instability is intensifying. This is due to an increase in the number of communication devices in information and telecommunication networks, as well as an increase in the number of possible attacks that can be used to disrupt the operation of an information and telecommunication network. Considering the above, the object of research is a special purpose information and telecommunication system. The subject of research is cyber security of a special purpose information and telecommunication system. Classical methods of scientific knowledge, namely analysis and synthesis, were used during the research. The research identifies factors that affect cyber security in a special purpose information and telecommunications system. All this must be taken into account while planning and deploying a special purpose information and telecommunication system. The analysis of the consequences of the impact on the information and telecommunications system of special purpose of modern devices of defeat and the impact of devices of radio-electronic suppression and other factors was carried out. A typical special purpose information and telecommunication system does not fully meet the requirements for constant readiness to ensure the management of troops (forces), stability, mobility and throughput. A formalized description of the task of improving cyber security in a special purpose information and telecommunications network is provided. The components that affect the level of cyber security of the special purpose information and telecommunication network during the group's operations have been established. The impact of the specified conditions and factors must be reflected: in the planning documents during the planning of the deployment and operation of the group's information and telecommunications system; in the software, during operational management.

Texte intégralRésumé :
Swarm intelligence, as demonstrated by natural biological swarms, has numerous powerful properties desirable in many engineering systems, such as telecommunication. Communication network management is becoming increasingly difficult due to the increasing size, rapidly changing topology, and complexity of communication networks. This paper describes how biologically-inspired agents can be used to solve control problems in telecommunications. These agents, inspired by the foraging behaviour of ants, exhibit the desirable characteristics of simplicity of action and interaction. The colle ction of agents, or swarm system, deals only with local knowledge and exhibits a form of distributed control with agent communication effected through the environment. In this paper we explore the application of ant-like agents to the problem of routing in telecommunication networks.

Texte intégralRésumé :
In order to identify the role of data storage in the monitoring system of a telecommunications device, a conceptual design method was used, which was based on the basic principles of the Telecommunication Management Network concept, which is a network management system for telecommunication operators. Based on this concept, it was possible to design a data storage model in the monitoring system of a telecommunications device, which clearly reflects the separation of databases involved in the telecommunications network at different levels of the concept. A description of the differences between the databases assigned to each specific level from each other and an explanation of the functional features of each of the databases under consideration, as well as a description of the data circulation process over the network, is presented. The work focuses on describing the contents of the database of a specific telecommunications device, which is the object of control in the communication network, with the possibility of developing an interface to this database, which makes it convenient to search, view and modify stored data. To designate the information stored in the database of a telecommunications device, a fragment of the database was developed containing a set of attributes characterizing the device, their values and parameters of attribute values. The role of the database interface is to enable the user to quickly and easily access the information contained in the database.

Texte intégralRésumé :
The article formulates the main tasks of management of information networks and telecommunications services in terms of ensuring their reliable operation. The telecommunication network is considered as a complex system consisting of many components, each of which has its own characteristics of operation during operation. The main functions of the telecommunication network control system are determined: fault detection and network status diagnostics, network device administration, forecasting and elimination of congestion and other possible deviations in network functioning, ensuring coordinated interaction between different types of control systems for providing telecommunication services with specified quality. Methods of analysis and management of networks are essentially a kind of identification methods, i.e. the current assessment of the parameters and condition of complex technical systems. There is a close relationship between identification and diagnostic tasks. The methods for solving these problems largely depend on the class to which the identification object can be assigned. Computer and telecommunication networks belong to the class of distributed systems with delays in signal and control information. Methods of retrospective identification are used to analyze the state of such systems. The influence of delays of signal and control information on the efficiency of search and determination of places of failures, overloads and emergency modes in communication networks is investigated. The results of computer simulation are given. The approach based on regular control of parameters and condition of network nodes taking into account delays of receipt of information on parameters and a condition of a concrete network node and delays of the control information necessary for adjustment of parameters of a network node as control object has found further development.

Texte intégralRésumé :
The purpose of this survey study is to shed light on the importance of knowledge usage and knowledge-driven applications in telecommunication systems and businesses. To this end, we first define a classification of the different knowledge-based approaches in terms of knowledge representations and reasoning formalisms. Further, we define a set of qualitative criteria and evaluate the different categories for their suitability and usefulness in telecommunications. From the evaluation results, we could conclude that different use cases are better served by different knowledge-based approaches. Further, we elaborate and showcase our findings on three different knowledge-based approaches and their applicability to three operational aspects of telecommunication networks. More specifically, we study the utilization of large language models in network operation and management, the automation of the network based on knowledge-graphs and intent-based networking, and the optimization of the network based on machine learning-based distributed intelligence. The article concludes with challenges, limitations, and future steps toward knowledge-driven telecommunications.

Texte intégralRésumé :
The telecommunications operators have to manage one of the most complex systems developed by human beings. Moreover, the new technological developments, the convergence of voice and data networks and the broad range of services still increase this complexity. Such complex object as telecommunication network requires advanced software tools for their planning and management. Telecommunications operators collect large volumes of the data in various databases. They realize that the knowledge in these huge databases might significantly improve various organizational strategic and operational decisions. However, this knowledge is not given explicitly, it is hidden in data. Advanced methods and algorithms are being developed for knowledge extracting. In this paper we will focus on using data mining for solving selected problems in telecommunication industry. We will provide a systematic overview of various telecommunications applications.

Texte intégralRésumé :
The rapid advancements in the telecommunication networks, has led to the day by day progress in the data communication leading to the inclusion of many devices that causes complexities in managing and the maintaining of the networks. The outgrowing number of new network devices makes the traditional telecommunication networks incompatible to their flexible operation and the management. So the trending software defined networking can be opted for the provision of more convenient service providing a seamless communication, but the SDN’s lags in the self-adaptability and the efficient usage of the resources as it uses the concept of the traditional networks so the paper proposes an modified method of software defined networking based on the deep learning to enhance the performance, of the telecommunication networks. Further the evaluation of the telecommunication network routing with the improvised SDN, on the packet loss rate and the average delay shows that the proposed method is compatible for the seamless information provision of the nowadays telecommunication networks.

Texte intégralRésumé :
The article reflects the views of the authors on the method for the operational calculation of the indicator of the functioning of special-purpose information and telecommunication networks of the tactical level of control according to the criterion of "network availability". Improvement of weapons and military equipment, forms and methods of combat, as well as a change in views on command and control, put forward ever more stringent requirements for the information and telecommunication system in general and for its elements in particular. The problems of development, planning of combat use and operation of information and telecommunication networks of the tactical control level are their heterogeneity, since they use heterogeneous transmission systems (radio and wire) together. The characteristic features of the planning, deployment and operation of information and telecommunication networks of the tactical control level are a high degree of uncertainty in the characteristics of their functioning and the lack of initial data in planning, which necessitates the improvement of the methodological basis for conducting operational calculations. Based on the analysis of ITU-T recommendations, scientific publications and the practice of combat use of the defense forces, it becomes clear that the operational calculation of individual criteria and indicators of the functioning of information and telecommunication systems of the tactical control level needs to be improved, since these systems have their own characteristic features. The material presented in the article makes it possible to develop new approaches to solving the problem of a reasonable calculation of the required bandwidth of the access node of the information and telecommunications network of the tactical control link. The significance and value of this study lies in the fact that in the conditions of continuous improvement of the forms and methods of warfare, high dynamism of changes in the states of information and telecommunication systems of the tactical control level, the correct choice of the apparatus for assessing the decisions made should play a decisive role in shortening the deployment planning cycle and sustainable functioning of the system management.

Texte intégralRésumé :
The article is devoted to the problems of advanced workforce management systems WFM (Workforce Management) of post-NGN telecommunication operators, a formalized approach to the description of extended WFM functionality and mathematical WFM models are discussed. The proposed approach allows to develop new WFM tools for telecommunications operators to increase their performance, to manage more effectively the work schedules of engineering employees of the company, visit customer sites, and control the workload of engineers in real-time. Workforce Management systems (WFM) of Next Generation Networks (NGN) are becoming more and more important. Compared to the routine distribution of requests between telephone technicians in the repair bureau of the old Public Switched Telephone Network (PSTN) in the last century, the modern WFM system operates with a disproportionately large set of functions, a wide range of professional competencies and key performance indicators (KPIs). In partnership with WFM, other new information technology tools (IT-landscape) of the telecommunications operator, elements of BSS (Business Support Systems), human resource accounting (HR) software, enterprise resource planning (ERP) systems, other workforce planning, and management tools employee vacations, the timing of basic engineering operations at the operator's and customer's premises, and other support tools to optimize the performance of the required work by personnel, increase productivity and reduce costs.

Texte intégralRésumé :
Modern communication networks for special purposes —communication networks designed for the needs of state authorities, the needs of the country's defense, state security and law enforcement - these are complex decentralized network structures that use the resources of public communication networks and commercial communication protocols. The management of such structures requires a transition to new management models, since hierarchical and distributed static network management systems, such as TMN and OSS/BSS, no longer fully meet the requirements for managing state and military networks. These systems provide only partial automation of decision-making in network management. They are still not ready for constant changes and are not able to adapt to them because of their rigidly static nature. Also, over time, control systems will encounter such a problem as the heterogeneity and mobility of a huge number of network devices in the - mobile control and managed devices, drones, wearable networks, etc. As a result of all of the above, it becomes necessary to search for new models and methods for building telecommunication management systems. From the point of view of managing such infrastructures, the transition to distributed cognitive management models, as well as models that take into account the volume and context of data generated by control systems in the process of their functioning, is gaining importance. In this paper, the authors considered the evolution of networks control models: starting with traditional approaches and moving on to modern models and methods for managing telecommunications of the future. In the course of the study, in addition to studying traditional approaches to telecommunication management, a cognitive model based on multi-agent self-organization was identified and the relevance of this approach to managing post-NGN networks was examined.

Texte intégralRésumé :
Trust to modern telecommunications networks plays an important role as a driver of technological and market success of any technology or telecommunication services. Most of the technological approaches to this problem are focused only on network security and do not include such a factor as the quality of service (QoS), which also plays an important role in the formation of trust both from the consumers and the regulator. The future 5G mobile technology will be the engine of development of telecommunications until 2020 and the formation of trust to the 5G networks is one of the main tasks for developers. The authors present the view on the trust to 5G networks in the plane of QoS requirements formation and QoS management. QoS requirements to 5 G networks were determined on the basis of three main business models of services: xMBB, M-MTC and U-MTC and the need to ensure user trust to networks. Infrastructure requirements for QoS control and spectrum management network entities which are based on Network Function Virtualization (NFV) principles have been formed.

Environmental safety and natural resources 40, no 4 (24 décembre 2021) : 5–20. http://dx.doi.org/10.32347/2411-4049.2021.4.5-20.
Texte intégralRésumé :
The article defines the system features, properties and characteristics of information and telecommunication networks of automated environmental safety systems: information reliability and proven efficiency as a fundamental characteristic of system perfection. The main task of this research is to standardize the highest level of information and telecommunications networks architecture that provide the creation, processing, storage, deletion and transportation of information. In this case, the architecture is considered as a single for: all types of networks (including network services): optical transport network, Internet network (data network), fixed telephone network, mobile network and all types of products, customers, services, resources, aspects of management. A very important requirement is that the system architecture should not change when changing the structure of products, market requirements or the structure of the company. Standardization of information systems architecture involves: defining a complete list of architecture components; determination of functional boundaries of components; definition of interfaces (protocols) of interaction of components. The main purpose of architecture standardization is: to reduce the implementation of telecommunications services by reducing the time for implementation and modernization of information systems, and increase the efficiency of implementation of information systems, as well as reduce costs for their creation and operation by: avoiding duplication of functions; use of open interfaces; repeated use of the same type of elements. The research concerns the structural synthesis of the architectures of four main telecommunication networks: transport, IP, mobile and fixed. Eight sets of network resources (levels) were selected to standardize each network architecture. Based on the results of the analysis, it is possible to draw a conclusion about the development potential of each network depending on the trends of modern telecommunications services. The telecommunication services means of production architecture, which include platforms of network resources and network services, is considered. The article proposes a methodological basis for the synthesis of information and communication technology systems in order to establish a single information platform, which is presented as a universal architecture of information and communication systems. The messaging service is considered in the context of: one workstation, one domain and interconnection between domains. The efficiency of information transmission systems is considered. When evaluating different communication systems, two indicators were taken into account: efficiency and noise immunity; their combination gives a fairly complete description of the system. The most perfect system is the one that provides the greatest efficiency at a given noise immunity or, conversely, the greatest noise immunity at a given efficiency.

Texte intégralRésumé :
The features of the application of information and telecommunication technologies in high-tech enterprises are examined in order to increase the efficiency of production activities. It is determined that the basis of telecommunication technologies is the procedure for information exchange and data transfer. Telecommunication technologies provide remote transmission of all forms of information, including data, voice, video, between computers via various types of communication lines. Analysis of the results of the classification of information technologies and areas for improving information support in the production of high-tech products allowed us to identify trends in the development of modern information technologies. These trends are due to the dynamics of the development of industrial enterprises and the external environment, which leads to functional changes in the management system of a high-tech enterprise and provides significant economic growth in developed countries. The main promising means for data transmission are the Internet, wireless mobile radio networks, laser and fiber-optic communication lines. The most important task of telecommunication technologies in the field of economics is electronic exchange. This indicates the importance of the telecommunications aspect in the functioning of the information system. Telecommunication technologies that provide data transfer, make it possible to implement a continuous exchange of information through global networks. Modern telecommunication technologies are widely used in creating network options for information technology. It was determined that a significant achievement of telecommunication technologies was the possibility of real-time control of financial, banking, trading and other operations regardless of the territorial location of their participants. Telecommunication technologies are becoming the elements that informally unite the vast territory of Russia.

Texte intégralRésumé :
Digitalization is one of the factors that affects the acceleration of the application of telecommunications technologies such as 5G. The 5G technology that has been developed today does not yet meet different performance and manageability standards, particularly for data center networks as a supportive technology. Software-defined networking (SDN) and network function virtualization (NFV) are two complementary technologies that are currently used by almost all data centers in the telecommunications industry to rectify performance and manageability issues. In this study, we deliver an integrated SDN-NFV architecture to simplify network management activities in telecommunication companies. To improve network performance at the computing level, we performed a modification of a networking system at the computing level, underlying NFV devices by replacing the default virtual switch with a data plane development kit (DPDK) and single root I/O virtualization (SR-IOV). This study evaluated the proposed architecture design in terms of network performance and manageability. Based on 30 days of observation in prime time, the proposed solution increased throughput up to 200 Mbps for the server leaf and 1.6 Gbps for the border leaf compared to the legacy architecture. Meanwhile, the latency decreased to 12 ms for the server leaf and 17 ms for the border leaf. For manageability, we tested three different scenarios and achieved savings of 13 min for Scenario 1, 22 min for Scenario 2 and 9 min for Scenario 3.

Texte intégralRésumé :
In this paper, we present a novel DC-centric architecture of telecommunication networks for next generation Internet. Data flow become the major traffic in existing telecommunication networks. Traditional computer networks and telecom networks meet many challenges in high-quality service, innovation, evolution, and management. Based on analysis existing telecom networks’ challenges, a DC-centric telecom network architecture with splitting the data plane from the control plane is proposed. The DC-centric telecom network is a widely-distributed data center network (DCN), which is composed of thousands of public or private DCs. Each DC not only plays the role of storage and computing, but also is a network node of data aggregation, switching, and routing. We also design an optical switching, which is evaluated by experiment.

Texte intégralRésumé :
Compensation is an activity carried out by students outside class hours as a sanction for the student's absence from attending scheduled lectures. In this era, information is really needed, especially information on compensation in lectures. Initially compensation on digital telecommunications networks was still done manually or by coming directly to the admin to ask about compensation. But after this system is created, it will improve the compensation system on digital telecommunications networks. Students only need to access the website and no longer need to come to campus to find out information about compensation. The website has been designed in such a way to make things easier for students. This system is very useful for students because all compensation matters can be done via the website so it will be more effective for students. The problem with the Digital Telecommunication Network Study Program is that 84% of students have not compensated and only 16% of students have compensated. Based on these problems, development was carried out in the form of designing a web-based compensation information and registration system using biometric fingerprints for sending compensation agreements using a telegram bot. The information system used is a series of biometric systems with fingerprint sensor devices with FPM10A module, Telegram Bot, Arduino and ESP32 features and produces a system prototype that can provide information about compensation and compensation registration to polynema students so that it can make things easier for students of the Digital Telecommunication Network Study Program Malang State Polytechnic in paying compensation

Texte intégralRésumé :
The object of the current research is the process of routing data packets in a telecommunications network. It was established that the state and parameters of data transmission channels and routers could have a negative impact and need to be taken into account in the process of modeling the routing of data packets in telecommunication networks. A model of simulated dynamic modeling of data packet routing in telecommunication networks has been devised and proposed. The suggested model makes it possible to establish quantitative values of the delay time of processing data packets during their routing along a separate segment of the telecommunications network, taking into account the state and parameters of the data transmission channel and routers. It has been established that the achievement of the minimum delay time of data packets during routing is achieved by choosing the path of their transmission under the condition of minimum transmission time by communication lines and the capabilities of routers in terms of their accumulation and service speed. At the same time, the reduction of packet transmission delay time relative to the average for the time network segment can reach from 21 to 38 percent. It is shown that the main factor affecting the value of the delay time is the speed of data processing along the selected path of packet transmission. The number of routing nodes in a separate data transmission path can affect the delay time only if the parameters of the routers are equal compared to others that are included in alternative routes. The model of simulated dynamic modeling of data packet routing reported in this work, unlike the existing ones, takes into account the state and parameters of data transmission channels and routers. It can be used in practical improvement of existing and development of new multi-service telecommunication communication networks

Texte intégralRésumé :
The certificate management complexity and cost increase when PKI technology is leveraged into Network Function Virtualisation (NFV), a significant enabling technology for 5G networks. The expected security of PKI cannot be met due to the unavailability of the certificate revocation inquiry in the telecommunication operator’s core network. This paper analyses the issues and challenges during the NFV implementation and proposes a blockchain-based decentralized NFV certificate management mechanism. During instantiation, the Virtual Network Functions (VNF) instance generates certificates according to the certificate profile provided in the VNF package. The certificate management unit is responsible for the certificate enrolment, renewal, and revocation. The certificates submitted to the decentralized certificate management system by the instance will be recorded into the ledger after validation and consensus. The experiment and analysis show the transaction throughput, and the transaction delay is noncritical in practice, which could be fulfilled by the proposed mechanism. The certificate inquiry performance is critical, which can be facilitated by the decentralized deployment of inquiry nodes.

Texte intégralRésumé :
The recommendation architecture has been proposed as a system architecture which can enable a system to learn to perform a complex combination of interrelated functions. The capability of a system with the recommendation architecture to learn to manage complex telecommunication backbone networks has been investigated. A network model with a number of nodes and links and carrying realistic but randomly generated traffic was used as the target for the management system. Traffic data taken from the model was used as input to the recommendation architecture system. The traffic data was organized into inputs once every 5 minutes, and the management system organized these inputs into a hierarchy of repetition similarity. It was demonstrated that the outputs of this hierarchy provided information on the condition of the network. This output information was a compressed version of the inputs which correlated with major network conditions.

Texte intégralRésumé :
The development of telecommunication technology in the last three or more decades has created the conditions for high quality and high speed data transmission between physically separated devices (central computers, terminals, mobile devices). Telecommunication can be defined as the electronic connection of physically (geographically) remote computers, and the telecommunication system as a component of compatible telecommunication devices connecting physically separated devices that can transmit text, image, audio and video information. The paper focuses on the choice of telecommunication providers in Serbia. It examines the attitudes of service users and what influences their choice of a particular mobile network. Consumer attitudes can influence the improvement of service management of mobile operators in Serbia. The paper represents a modest contribution to the use of telecommunication technologies to improve the existing offer on the market of mobile operators in Serbia and especially in the eastern region of the country. The city of Zajecar, the largest city in the eastern region of Serbia, is included in the study as a representative example.

The monitoring of cultural heritage is becoming common in cities to provide heritage preservation and prevent vandalism. Using sensors and video cameras for this task implies the need to transmit information. In this paper, the teletraffic that cameras and sensors generate is characterized and the transmissions’ influence on the municipal communications network is evaluated. Then, we propose models for telecommunication traffic sources in an intelligent municipal heritage management service inside a smart sustainable city. The sources were simulated in a smart city scenario to find the proper quality of service (QoS) parameters for the communication network, using Valencia City as background. Specific sensors for intelligent municipal heritage management were selected and four telecommunication traffic sources were modelled according to real-life requirements and sensors datasheet. Different simulations were performed to find the proper CIR (Committed Information Rate) and PIR (Peak Information Rate) values and to study the effects of limited bandwidth networks. Packet loss, throughput, delay, and jitter were used to evaluate the network’s performance. Consequently, the result was the selection of the minimum values for PIR and CIR that ensured QoS and thus optimized the traffic telecommunication costs associated with an intelligent municipal heritage management service.

Texte intégralRésumé :
The high availability of computer networks is a prerequisite in large companies and service providers. Thus, computer network administrators are called upon to face the various growing challenges related to unscheduled downtime of services; lack of expertise; lack of tools; the complexity of technologies; market consolidation and competition to provide better quality services. It should be remembered that the organization of the networks of telecommunication aims at giving control of the phenomena which occur there, during the treatment of the communications, and more generally of the services which they offer. These phenomena are governed by the randomness of the appearance of the requests, and are studied independently of the choices of technology implemented. They are amenable to the formalism of the calculation of probabilities, and give birth to the notion of traffic, which will play a central role in their apprehension, given that they condition for a large part the effective structure of modern networks. This research specifically examines the problems of optimization of signal performance in traffic management of local area networks of companies in the Democratic Republic of Congo, by presenting the different elements of network traffic theory and quality. Thus demonstrating their impact on the architectures of networks and computer systems, and at the same time introducing the major problems faced by IT network administrators on a daily basis; The main objective of this research is to evaluate the development performance of computer and telecommunications networks according to their applications in the areas of network design, equipment dimensioning, and characterization and quality measurement.

Texte intégralRésumé :
Wireless sensor networks are becoming increasingly important in both the civilian and military fields. The object of this study is the process of collecting data by a telecommunication aerial platform from network nodes under conditions of their remoteness from the telecommunication infrastructure. Most available papers consider a solution to partial problems related to the process of data acquisition by a telecommunication aerial platform: clustering of the network, search for the shortest flight route, minimization of energy costs of nodes, etc. Therefore, an improved method of direct data collection by a telecommunication air platform is proposed, which consistently and comprehensively solves these problems. Unlike existing methods, it takes into consideration several objective functions (optimization of data collection time by a telecommunication air platform and a network functioning time), parameters of the state of nodes and clusters, as well as makes it possible to obtain solutions in real time. A special feature of the proposed method is the search for the optimal solution according to the hierarchy: network – cluster – node. At the network level, the following is optimized: the number of clusters of a certain dimensionality and the trajectory of the cluster flyby. At the cluster level, the points (intervals) of data collection during the freezing (in motion) of the telecommunication air platform and the trajectory of its flight within a cluster are determined. At the node level, its energy consumption is minimized by reducing the distance to the telecommunication aerial platform. The trajectory of the platform within a cluster is calculated according to the developed rule base. The rules implement the method of situational management. The conditions of application are the parameters of the state of the nodes, the solutions are the parameters of the trajectory of a telecommunication aerial platform, and the intervals of data acquisition. The rules take into consideration the priority of the objective functions, the state of the parameters of the cluster nodes, and the previously made basic decision on the trajectory of the flyby. The simulation results show that the application of the method reduces the time of data collection up to 15 % or increases the network functioning time to 17 %.

Texte intégralRésumé :
As we all know that in the present time of technology peoples of whole world are directly or indirectly connected each other and telecommunication sector plays a significant role in this connectivity. India's telecommunication network is the second largest network in the world based on the total number of telephone users (both fixed and mobile phone) and it has the world's third-largest Internet user-base. According to the Internet and Mobile Association of India, the Internet user base in the country stood at 190 million at the end of June, 2013. The performance of any organization depends upon the proper and efficient management of financial resources. The better management of financial resources positively affects the solvency, turnover and earning capacity. Under this research paper four major Indian telecommunication companies are selected and various ratios as current ratio, debt-equity ratio, assets turnover ratio and net profit ratio have been calculated for the purpose of comparison of the solvency, turnover and earning capacity in respect of financial resources management.

Texte intégralRésumé :
Many military research efforts have concentrated on how to allow war-fighters to take advantage of all available information within the battlefield in a rapid and flexible manner. As a result, the development of the Global Information Grid (GIG) was the key enabler for this process; hence, adding to the development of the mobile networking part of the GIG, the concept of the Mobile Ad hoc Network of Networks (MANoN) is introduced. This article proposes a novel security management algorithm achieving the three management essentials: Security Administration; Prevention and Detection; and Containment and Recovery; based on the International Telecommunication Union’s recommendation M.3400 to manage securely the future of military Network-Centric Warfare (NCW). The authors will employ Interval Temporal Logic (ITL) as a method of handling both sequential and parallel composition in flexible timely constrains, in addition, this technique will be evaluated using the Network Simulator (NS-2) to provide and check whether security requirements are met in a comprehensive manner.

Texte intégralRésumé :
The telecommunication system being a critical pillar of emergency management, intelligent deployment and management of slices in an affected area will help emergency responders. Techniques such as automated management of Machine Learning (ML) pipelines across the edge and emergency responder devices, usage of hierarchical closed-loops, and offloading inference tasks closer to the edge can minimize latencies for first responders in case of emergencies. This study describes the major results from building a Proof of Concept (PoC) for network resource allocation for emergency management using a hierarchical autonomous Artificial Intelligence (AI)/ML-based closed-loops in the mobile network, organized by the Internal Telecommunication Union Focus Group on Autonomous Networks (ITU FG-AN). The background scenario for this PoC included the interaction between a higher closed-loop in the Operations Support System (OSS) and a lower closed-loop in Radio Access Network (RAN) to intelligently share RAN resources between the public and the emergency responder slice. Representation of closed-loop "controllers" in a declarative fashion (intent), triggering "imperative actions" in the "underlay" based on the intent, setup of a data pipeline between various components, and methods of "influencing" lower layer loops using specific logic/models, were some of the essential aspects investigated by various teams. The main conclusions are summarised in this paper, including the significant observations and limitations from the PoC as well as future directions.

Texte intégralRésumé :
Background: In intensive case management (ICM), users receive a wide variety of services of varying content, which makes it difficult to understand the global features of ICM programs. Aims: The aim of this study was to examine the features of ICM programs using network analysis. Methods: A total of 233 ICM users in two Japanese medical institutions were recruited to participate. All received services were recorded for 2 months. In the network analysis, nodes represented types of ICM services and edges between two nodes depicted when over 5% of participants received both types of services. Results: We found high centrality values for ‘H5. Hospital-based counseling’, ‘O13. Outreach support for mental health medications’, ‘H13. Hospital-based support for mental health medication’, ‘T5. Counseling via telecommunication’, ‘H3. Hospital-based coordination of services in the medical institution’ and ‘T2. Coordination of services with other institutions via telecommunication’. These results indicated that these services were associated with various other types of services. Social functioning was related to ‘O13. Outreach support for mental health medication’, whereas need for ICM was related to ‘H13. Hospital-based support for mental health medications’, ‘T5. Counseling via telecommunication’ and ‘T2. Coordination of services with other institutions via telecommunication’ Conclusion: Based on these findings, we speculated that there are at least five types of core services in ICM: regular face-to-face contact, outreach services, hospital-based services, easy contacts and coordination. These findings clarified the features of ICM programs, which may help improve the understanding of case managers’ practice.

The performance indicators fiber-optic communication lines using spectral technology with separation communication channels are analyzed. The effectiveness of the use network resources optical telecommunication systems using spectral technologies based on the architectural concept of the next NGN (NGN, Next Generation Network) and future FN (FN, Future Network) networks has been studied. This work is devoted to the construction methods for calculating the indicators optical networks and the study methods and tools for improving the efficiency using network and channel resources fiber-optic communication lines using dense spectral multiplexing optical signals with separation communication channels. The problem ensuring effective management channel and network resources in optical communication networks are considered. As a result of the study technology spectral multiplexing, a new approach to the construction of a calculation method is proposed that describes the efficiency managing network and channel resources in fiber-optic communication lines, taking into account the numerous requirements their parameters and transfer characteristics. On the basis of the calculation method, analytical expressions are obtained that allow estimating the resources of the system, indicators informational and spectral efficiency of the functioning fiber-optic communication lines. The results of the research can be applied by cellular operators when designing an optical telecommunications network, in particular, to determine the optimal value of the capacity optical systems based on wavelength multiplexing technology and modulation spectral efficiencies.
