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…
Packed to the Brim: Investigating the Impact of Highly Responsive Prefixes on Internet-wide Measurement Campaigns
Patrick Sattler, Johannes Zirngibl, Mattijs Jonker +3
Internet-wide scans are an important tool to evaluate the deployment of services. To enable large-scale application layer scans, a fast, stateless port scan (e.g., using ZMap) is o…
QUIC on the Highway: Evaluating Performance on High-rate Links
Benedikt Jaeger, Johannes Zirngibl, Marcel Kempf +2
QUIC is a new protocol standardized in 2021 designed to improve on the widely used TCP / TLS stack. The main goal is to speed up web traffic via HTTP, but it is also used in other…
Evaluating the Benefits: Quantifying the Effects of TCP Options, QUIC, and CDNs on Throughput
Simon Bauer, Patrick Sattler, Johannes Zirngibl +2
To keep up with increasing demands on quality of experience, assessing and understanding the performance of network connections is crucial for web service providers. While differen…
A First Look at SVCB and HTTPS DNS Resource Records in the Wild
Johannes Zirngibl, Patrick Sattler, Georg Carle
The Internet Engineering Task Force is standardizing new DNS resource records, namely SVCB and HTTPS. Both records inform clients about endpoint and service properties such as supp…
QUIC Hunter: Finding QUIC Deployments and Identifying Server Libraries Across the Internet
Johannes Zirngibl, Florian Gebauer, Patrick Sattler +2
The diversity of QUIC implementations poses challenges for Internet measurements and the analysis of the QUIC ecosystem. While all implementations follow the same specification and…
Target Acquired? Evaluating Target Generation Algorithms for IPv6
Lion Steger, Liming Kuang, Johannes Zirngibl +2
Internet measurements are a crucial foundation of IPv6-related research. Due to the infeasibility of full address space scans for IPv6 however, those measurements rely on collectio…
Rusty Clusters? Dusting an IPv6 Research Foundation
Johannes Zirngibl, Lion Steger, Patrick Sattler +2
The long-running IPv6 Hitlist service is an important foundation for IPv6 measurement studies. It helps to overcome infeasible, complete address space scans by collecting valuable,…
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…
Towards a Tectonic Traffic Shift? Investigating Apple's New Relay Network
Patrick Sattler, Juliane Aulbach, Johannes Zirngibl +1
Apple recently published its first Beta of the iCloud Private Relay, a privacy protection service with promises resembling the ones of VPNs. The architecture consists of two layers…
Active TLS Stack Fingerprinting: Characterizing TLS Server Deployments at Scale
Markus Sosnowski, Johannes Zirngibl, Patrick Sattler +4
Active measurements can be used to collect server characteristics on a large scale. This kind of metadata can help discovering hidden relations and commonalities among server deplo…
Analyzing Locality of Mobile Messaging Traffic using the MATAdOR Framework
Quirin Scheitle, Matthias Wachs, Johannes Zirngibl +1
Mobile messaging services have gained a large share in global telecommunications. Unlike conventional services like phone calls, text messages or email, they do not feature a stand…
