Waiting for QUIC: Passive Measurements to Understand QUIC Deployments
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +6
QUIC experiences a rapid adoption since its standardization in 2021, and hypergiants configure their infrastructure to optimize for QUIC performance. In this paper, we introduce a…
QUIC Steps: Evaluating Pacing Strategies in QUIC Implementations
Marcel Kempf, Simon Tietz, Benedikt Jaeger +3
Pacing is a key mechanism in modern transport protocols, used to regulate packet transmission timing to minimize traffic burstiness, lower latency, and reduce packet loss. Standard…
ECSeptional DNS Data: Evaluating Nameserver ECS Deployments with Response-Aware Scanning
Patrick Sattler, Johannes Zirngibl, Fahad Hilal +4
DNS is one of the cornerstones of the Internet. Nowadays, a substantial fraction of DNS queries are handled by public resolvers (e.g., Google Public DNS and Cisco's OpenDNS) rather…
Lazy Eye Inspection: Capturing the State of Happy Eyeballs Implementations
Patrick Sattler, Matthias Kirstein, Lars Wüstrich +2
Happy Eyeballs (HE) started out by describing a mechanism that prefers IPv6 connections while ensuring a fast fallback to IPv4 when IPv6 fails. The IETF is currently working on the…
A Quantum of QUIC: Dissecting Cryptography with Post-Quantum Insights
Marcel Kempf, Nikolas Gauder, Benedikt Jaeger +2
QUIC is a new network protocol standardized in 2021. It was designed to replace the TCP/TLS stack and is based on UDP. The most current web standard HTTP/3 is specifically designed…
