Linux Processes Repurposed for High‑Performance Network Simulation

The paper explores a technique that leverages existing Linux processes for network simulation. It targets high‑performance scenarios where traditional simulators struggle. The authors modify process scheduling to emulate network traffic. Experiments demonstrate throughput gains compared to baseline tools. The approach reduces the need for specialized simulation hardware. Results were presented at the 2022 USENIX Annual Technical Conference. The work highlights the flexibility of the Linux kernel for research purposes. Future work may extend the method to larger distributed systems.
