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…
P4-TAS: P4-Based Time-Aware Shaper for Time-Sensitive Networking
Fabian Ihle, Moritz Flüchter, Michael Menth
Time-sensitive networking (TSN) is a set of IEEE standards that extends Ethernet with real-time capabilities. Among its mechanisms, the time-aware shaper (TAS) periodically opens a…
MPLS Network Actions: Technological Overview and P4-Based Implementation on a High-Speed Switching ASIC
Fabian Ihle, Michael Menth
In MPLS, packets are encapsulated with labels that add domain-specific forwarding information. Special purpose labels were introduced to trigger special behavior in MPLS nodes but…
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…
