Research on client-server protocols to improve fault tolerance and connection security

This study is a comparative analysis of three key communication protocols used to build modern client-server applications: WebSocket, HTTP/2.0 and HTTP/3.0. Special attention is paid to comparing the strengths and weaknesses of each protocol, including aspects such as performance, efficiency, reliability, security and complexity of implementation. The purpose of this analysis is to help system developers and architects make an informed choice of the communication protocol that is most suitable for solving specific tasks. Understanding the advantages and disadvantages of each protocol, as well as the conditions under which they demonstrate maximum efficiency, allows you to optimize the performance and reliability of client-server interaction. As a result, the research provides valuable information for the design and development of highly efficient and modern web applications.
