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…
Impact of Packet Loss and Timing Errors on Scheduled Periodic Traffic with Time-Aware Shaping (TAS) in Time-Sensitive Networking (TSN)
Manuel Eppler, Steffen Lindner, Lukas Osswald +2
Time-Sensitive Networking (TSN) is a collection of mechanisms to enhance the realtime transmission capability of Ethernet networks. TSN combines priority queuing, traffic schedulin…
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…
Extensions to BIER Tree Engineering (BIER-TE) for Large Multicast Domains and 1:1 Protection: Concept, Implementation and Performance
Moritz Flüchter, Steffen Lindner, Fabian Ihle +2
Bit Index Explicit Replication (BIER) has been proposed by the IETF as a stateless multicast transport technology. BIER adds a BIER header containing a bitstring indicating receive…
