DPDS: A DPDK-Based Packet Delayer and Spacer
Etienne Zink, Fabian Ihle, Michael Menth
In this paper we tackle the problem of adding varying delay to packets for link emulation. Naive approaches either add more delay than desired or cause packet reordering, both of w…
High-Speed Generation of Periodic Traffic Patterns on P4TG for DDoS and Burst-Load Evaluation
Fabian Ihle, Etienne Zink, Michael Menth
Traffic generators are essential tools for evaluating the robustness and performance of networked systems. P4TG is an open-source, hardware-accelerated traffic generator implemente…
Enhancements to P4TG: Histogram-Based RTT Monitoring in the Data Plane
Fabian Ihle, Etienne Zink, Michael Menth
Modern traffic generators are essential tools for evaluating the performance of network environments. P4TG is a P4-based traffic generator implemented for Intel Tofino switches tha…
SENSOR: A Cost-Efficient Open-Source Flow Monitoring Platform
Gabriel Paradzik, Benjamin Steinert, Heinrich Abele +1
This paper presents a cost-effective and distributed flow monitoring platform for collecting unsampled IPFIX data exclusively using open-source tools, which is implemented at the U…
Rust Barefoot Runtime (RBFRT): Fast Runtime Control for the Intel Tofino
Etienne Zink, Moritz Flüchter, Steffen Lindner +2
Data plane programming enables the programmability of network devices with domain-specific programming languages, like P4. One commonly used P4-programmable hardware target is the…
Enhancements to P4TG: Protocols, Performance, and Automation
Fabian Ihle, Etienne Zink, Steffen Lindner +1
P4TG is a hardware-based traffic generator (TG) running on the Intel Tofino 1 ASIC and was programmed using the programming language P4. In its initial version, P4TG could generate…
