Preface

The demand for advance telecommunication services has increased dramatically over the last few years. This has led to technological changes with revolutionized engineering strat‐ egies to optimize network construction and operation. Telecommunication networks inte‐ grate with a wide range of technologies, including optical amplifiers, software architectures for network control and management, abstract algebra required to design error correction codes, and network modeling. This book presents research contributions towards new tech‐ niques, concepts, analysis of the telecom market's evolving trends, and infrastructure to pro‐ vide integrated voice, data, and video communications services that are critical to the operation and competitiveness of companies, governments, and other organizations.

*Chapter 1* presents the structure and dynamics of the main indicators of the Russian tele‐ communication services market for the growth of telecommunication companies. It takes in‐ to account its strong state protectionism, which is conditioned by the strategic importance and the high social significance of the telecommunications industry.

*Chapter 2* describes the design challenges in optimizing a hybrid quantum-classical network and the initial results, based on experimental and numerical analysis, to characterize and evaluate the distribution of secure data to the subscribers using the Quantum-to-the-Home (QTTH) transmission model. The presented results provide a solid base to enhance the exist‐ ing telecommunication infrastructure and modules to deliver end-to-end optical data en‐ cryption to subscribers.

*Chapter 3* explores BRACE—a cloud-based, integrated, one-stop center for software reliabil‐ ity modeling, testing, and defect analysis. Each of these is provided as-a-service to develop‐ ment teams. Initial implementation of BRACE includes a software reliability growth modeling algorithm, which provides defect prediction for both early and late stages of the software development cycle. To illustrate and validate the tool and algorithm, the authors also discuss key use cases, including actual defect and outage data from two large-scale soft‐ ware development projects from telecom products.

*Chapter 4* presents a concept of chaos-based physical layer protocol for secure communica‐ tion and hidden data transmission over an open network channel. The protocol is based on spectral keying of chaotic signals generated by nonlinear dynamical systems with delayed feedback. In this technique, the modulating information sequence controls the parameter of nonlinear elements, so that it switches the chaotic modes and changes the spectral structure of the signal, which is transmitted to the communication channel.

*Chapter 5* provides an overview of optical amplifiers. The optical amplifier is an important element in optical communication networks. Tremendous progress has been made recently

in erbium-doped fiber amplifiers, semiconductor optical amplifiers, Raman amplifiers, and other types of optical amplifiers. In semiconductor optical amplifiers (SOAs), electron-hole recombination occurs, whereas in Raman amplifiers, Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the incom‐ ing photons. In this chapter, the authors did the simulation for both the amplifiers. The re‐ sults showed that the transmission distance of the fiber Raman amplifier (FRA) is much further than the SOA shown by BER and Q-factor. However, this FRA system has higher power consumption when compared to the SOA system.

*Chapter 6* attempts to introduce the benefits and challenges of the Internet of Things (IoT) for telecommunications networks.

It is believed that the students who seek to learn the latest advanced research in telecommu‐ nication networks will need this book.

The analysis of the structure and dynamics of the main indicators of the Russian telecommunication services market shows the achievement of saturation state of this market and the exhaustion of extensive sources of growth. Given the presence of a complex of negative socioeconomic factors, the source of maintaining the market positions of telecommunication companies is the customization of the services offered. For this purpose, the concept of the service products can be applied, involving the inclusion of the additional, accompanying and derivative services into the customer service package. The prerequisites for the application of the concept of the service product in the telecommunication field are the availability of the multiattribute properties and interdependence of elements in the product of that field. On the telecommunication market we can consider three types of service products. Customization of the Russian market of telecommunication services is carried out taking into account its strong state protectionism, which is conditioned by the strategic importance and the high social significance of the telecommunication industry. Saturation of the market in the conditions of oligopoly and sophistication of consumers stimulate the telecommunication companies to include in their market offer the service products of all three types. **Keywords:** telecommunications, technologies, services, telecommunication services market, service product, customization, additional service, accompanying service,
