Abstract
Systems and methods for providing application-layer characterization is disclosed. Quick User Datagram Protocol (UDP) Internet Connection (QUIC) is an end-to-end encrypted, transport-layer protocol, with a goal to improve communication security and quality of experience (QoE) towards end-users. The systems and methods disclosed herein relate to estimating application-level traffic attributes without decrypting QUIC packets. Based on size, timing, and direction information available in the encrypted packet, the system analyzes associated network traffic to infer an identity of each request and response pair, including time, size, and request-response match, as well as multiplexing feature in each QUIC connection. In the case of request and response multiplexing, several requests will be gathered and matched as a group with their corresponding responses, to form a super request-response pair. The inferred attributes may be used to evaluate the QoE of application-layer services and identify the service categories for traffic classification in the encrypted QUIC connections.
