A Survey of QUIC-Based Network Traffic Identification

With the QUIC (Quick UDP Internet Connection) protocol recognized by the Internet Engineering Task Force as the core protocol of HTTP/3, network traffic based on the QUIC protocol (also known as "QUIC traffic") will become one of the primary traffics on the Internet. Network administrators use QUIC traffic identification as the foundation for network management. Numerous studies on QUIC traffic identification and application are already underway with the goal of assisting network operators, and pertinent results are beginning to emerge. We evaluate the topic of QUIC traffic identification to help future researchers rapidly grasp the research frontier of QUIC traffic identification and to summarize the present research and understand the obstacles in the field.
