ECN with QUIC: Challenges in the Wild
Constantin Sander, Ike Kunze, Leo Blöcher +2
TCP and QUIC can both leverage ECN to avoid congestion loss and its retransmission overhead. However, both protocols require support of their remote endpoints and it took two decad…
Evolving the Digital Industrial Infrastructure for Production: Steps Taken and the Road Ahead
Jan Pennekamp, Anastasiia Belova, Thomas Bergs +16
The Internet of Production (IoP) leverages concepts such as digital shadows, data lakes, and a World Wide Lab (WWL) to advance today's production. Consequently, it requires a techn…
Tracking the QUIC Spin Bit on Tofino
Ike Kunze, Constantin Sander, Klaus Wehrle +1
QUIC offers security and privacy for modern web traffic by closely integrating encryption into its transport functionality. In this process, it hides transport layer information of…
Sharding and HTTP/2 Connection Reuse Revisited: Why Are There Still Redundant Connections?
Constantin Sander, Leo Blöcher, Klaus Wehrle +1
HTTP/2 and HTTP/3 avoid concurrent connections but instead multiplex requests over a single connection. Besides enabling new features, this reduces overhead and enables fair bandwi…
Video Conferencing and Flow-Rate Fairness: A First Look at Zoom and the Impact of Flow-Queuing AQM
Constantin Sander, Ike Kunze, Klaus Wehrle +1
Congestion control is essential for the stability of the Internet and the corresponding algorithms are commonly evaluated for interoperability based on flow-rate fairness. In contr…
L, Q, R, and T -- Which Spin Bit Cousin Is Here to Stay?
Ike Kunze, Klaus Wehrle, Jan Rüth
Network operators utilize traffic monitoring to locate and fix faults or performance bottlenecks. This often relies on intrinsic protocol semantics, e.g., sequence numbers, that ma…
Perceiving QUIC: Do Users Notice or Even Care?
Jan Rüth, Konrad Wolsing, Klaus Wehrle +1
QUIC, as the foundation for HTTP/3, is becoming an Internet reality. A plethora of studies already show that QUIC excels beyond TCP+TLS+HTTP/2. Yet, these studies compare a highly…
DeePCCI: Deep Learning-based Passive Congestion Control Identification
Constantin Sander, Jan Rüth, Oliver Hohlfeld +1
Transport protocols use congestion control to avoid overloading a network. Nowadays, different congestion control variants exist that influence performance. Studying their use is t…
A Performance Perspective on Web Optimized Protocol Stacks: TCP+TLS+HTTP/2 vs. QUIC
Konrad Wolsing, Jan Rüth, Klaus Wehrle +1
Existing performance comparisons of QUIC and TCP compared an optimized QUIC to an unoptimized TCP stack. By neglecting available TCP improvements inherently included in QUIC, compa…
Blitz-starting QUIC Connections
Jan Rüth, Konrad Wolsing, Martin Serror +2
In this paper, we revisit the idea to remove Slow Start from congestion control. To do so, we build upon the newly gained freedom of transport protocol extendability offered by QUI…
Application-Agnostic Offloading of Packet Processing
Oliver Hohlfeld, Helge Reelfs, Jan Rüth +4
As network speed increases, servers struggle to serve all requests directed at them. This challenge is rooted in a partitioned data path where the split between the kernel space ne…
The Dagstuhl Beginners Guide to Reproducibility for Experimental Networking Research
Vaibhav Bajpai, Anna Brunstrom, Anja Feldmann +6
Reproducibility is one of the key characteristics of good science, but hard to achieve for experimental disciplines like Internet measurements and networked systems. This guide pro…
Is the Web ready for HTTP/2 Server Push?
Torsten Zimmermann, Benedikt Wolters, Oliver Hohlfeld +1
HTTP/2 supersedes HTTP/1.1 to tackle the performance challenges of the modern Web. A highly anticipated feature is Server Push, enabling servers to send data without explicit clien…
Complying with Data Handling Requirements in Cloud Storage Systems
Martin Henze, Roman Matzutt, Jens Hiller +4
In past years, cloud storage systems saw an enormous rise in usage. However, despite their popularity and importance as underlying infrastructure for more complex cloud services, t…
The SensorCloud Protocol: Securely Outsourcing Sensor Data to the Cloud
Martin Henze, René Hummen, Roman Matzutt +1
The increasing deployment of sensor networks, ranging from home networks to industrial automation, leads to a similarly growing demand for storing and processing the collected sens…
HotBox: Testing Temperature Effects in Sensor Networks
Florian Schmidt, Matteo Ceriotti, Niklas Hauser +1
Low-power wireless networks, especially in outside deployments, are exposed to a wide range of temperatures. The detrimental effect of high temperatures on communication quality is…
Enabling Distributed Simulation of OMNeT++ INET Models
Mirko Stoffers, Ralf Bettermann, James Gross +1
Parallel and distributed simulation have been extensively researched for a long time. Nevertheless, many simulation models are still executed sequentially. We attribute this to the…
Support for Error Tolerance in the Real-Time Transport Protocol
Florian Schmidt, David Orlea, Klaus Wehrle
Streaming applications often tolerate bit errors in their received data well. This is contrasted by the enforcement of correctness of the packet headers and payload by network prot…
