This article analyzes methods for ensuring reliable real-time traffic transmission at the transport layer of a communication network. Traditional approaches implemented in the TCP and UDP protocols are considered, as well as a modern solution, the QUIC protocol. It is shown that QUIC combines the low latency of UDP with the reliability of TCP and additional advantages such as built-in encryption and multithreading. The results of a comparative performance analysis of QUIC and TCP are presented, demonstrating the advantages of the new protocol in various network conditions.
