Abstract: Modern methods of building information and communication systems are actively evolving in response to the growing needs for speed, reliability and flexibility of communication networks. Distributed information and communication systems are characterized by their ability to provide data processing and storage through a network of various autonomous components. These systems allow organizations to pool resources, reduce delays, and increase information availability [1]. Architectures of distributed systems can be divided into traditional and modern approaches. The traditional hierarchical architecture, as a rule, involves a clear structure, where information flows are organized by levels. This creates a clear and logical management scheme, but it can lead to bottlenecks in the system, especially when the size of data and requests grows significantly. Instead, modern approaches such as the Spine-Leaf architecture offer a more flexible and scalable solution [2]. The object of research is distributed information and communication systems characterized by increased reliability, as well as methods and technologies used for their construction and optimization in the conditions of a modern digital environment. The subject of the research is approaches and methods of increasing the reliability of distributed information and communication systems, as well as algorithms and technologies that ensure the effectiveness of their functioning in conditions of dynamic changes. The purpose of the work and research tasks. The purpose of the master’s qualification work is to analyze the methods of building distributed information and communication systems of increased reliability. In order to achieve the goal of the work is necessary to complete the following tasks: 1. To carry out a study of the main problems in the construction of reliable distributed systems and their solutions 2. Analyze modern methods of building information and communication systems. 3. To form a hybrid network infrastructure as an approach to building modern information and communication systems 4. Experimentally verify the effectiveness of the hybrid method of building distributed information and communication systems of increased reliability. Research methods. In the course of the work, an analysis of the scientific literature was carried out, experimental studies were carried out on the workbench, in order to determine the effectiveness of the hybrid method of building distributed information and communication systems of increased reliability. The scientific novelty of the mastery is that an integrated approach to the creation of hybrid information and communication systems has been developed, combining traditional methods with the latest technologies. This makes it possible to achieve higher reliability, adaptability and efficiency of system functioning in conditions of variable loads and potential threats. The results of the research can serve as a basis for further scientific developments in the field of information technology and security. The master’s thesis consists of an introduction, 5 chapters, a conclusion, a list of used sources and appendices. The first section of the master’s thesis explores the main threats affecting the reliability of distributed information and communication systems, including technical failures, human errors, cyber threats and natural disasters, was performed. A detailed review of the methods that ensure increased reliability of distributed information and communication systems was carried out [3]. The second section is devoted to traditional and modern approaches to building networks. Traditional architectures, in particular hierarchical models, ensure stability due to clearly structured levels of management and control, where each level has its clearly defined functions. This architecture is mostly built on centralized components that perform basic data processing and storage functions. Modern architectures such as Leaf-Spine offer a new approach based on the principles of decentralization and parallelization [4]. In these systems, the load is distributed among many elements, which allows for high performance and provides great flexibility [5]. In the third section, the performed study of the principle of building a network based on a hybrid infrastructure demonstrates. The main advantages of such an architecture are the use of a spine-leaf topology, which ensures uniform distribution of traffic and the absence of a single point of failure. Thanks to this approach, all components of the network are interchangeable and have the same configuration, which not only simplifies their maintenance, but also allows for rapid replacement of equipment, reducing the risk of loss of productivity in case of failures. In the fourth chapter, the testing of the hybrid network was carried out and its deployment demonstrated the high efficiency of the implementation of the infrastructure based on the spine-leaf topology. In particular, the ability to configure the entire Core Chunk in less than an hour is a significant advantage for the speed of implementation of network solutions
