Security Review and Performance Analysis of QUIC and TCP Protocols

In this study, the development process and basic features of the QUIC protocol have were introduced and the tests and analysis of the QUIC protocol in network environments and network devices were carried out comprehensively. On the client side, a test scenario was created using Curl and Quiche libraries, on the server side with Cloudflare. All network traffics were analyzed by recording pcapng packet files with Wireshark application. QUIC and TCP protocol page load time, throughput, performance and security analyzes have been conducted. In addition, Flow Control, Connection Carrying and Load, Reliable and Multiple Connections, Head-of Line Blocking and Congestion Control applications were analyzed comparatively within the scope of TCP and QUIC protocols. As a result of the analysis, it has been observed that the QUIC protocol outperformed the TCP protocol in the page load times, throughput and security applications. However, it has been found out that the QUIC protocol consumes more processing power than the TCP protocol with these applications. Although QUIC is a new protocol, it is considered that its usage in network traffic will continue to increase with both in performance and security.
