Quick User Datagram Protocol Internet Connection (QUIC) is a modern transport protocol leveraging the User Datagram Protocol (UDP) to improve latency, security, and mobility. In this study, we analyzed QUIC traffic by uploading a 10 MB file under varied maximum transmission unit (MTU), bandwidth, and segment size conditions. Interarrival times (IAT) at both client and server were captured and analyzed using ordering points to identify the clustering structure (OPTICS) clustering and Markov modelling. Transition matrices and eigenvalue spectra revealed steady states, convergence behavior, and spectral gaps. The results showed that parameter variations significantly affected the traffic state diversity and flow dynamics, optimizing QUIC performance in real-world deployments.
