Analysis and visualization of QUIC protocol deployment in Vietnam

抄録

Quick UDP Internet Connections (QUIC), an advanced IETF transport-layer protocol, offers several significant advantages over traditional TCP, including reduced latency, enhanced multiplexing capabilities, and strong security through built-in encryption and optimized handshake processes. Because of these benefits, even before its standardization in 2021, QUIC was widely deployed by major Internet companies such as Google and Facebook. Additionally, previous research has observed an increase in global adoption of QUIC. Motivated by this trend, we investigate QUIC deployment in Vietnam, particularly in the context of the country’s rapid development, especially in the ICT sector. Specifically, we scan and analyze QUIC adoption using a Vietnamese IPv4 dataset. The scanning results indicate that QUIC adoption in Vietnam is in the early stages, with a low deployment rate of approximately 0.05% of all Vietnamese IPv4 addresses. Furthermore, we analyze active migration support, TLS encryption preferences, and visualize a map of QUIC adoption to track its ongoing deployment patterns. In addition, we conduct active measurements showing that QUIC achieves lower time to first byte (TTFB) and higher throughput than TCP in Wi-Fi networks, while offering competitive performance in mobile networks.
