Co-opting Linux Processes for High-Performance Network Simulation (2022)
Summary
The article discusses Phantom, a high-performance network simulation tool that co-opts unmodified Linux processes through advanced process control and system-call interposition. It demonstrates substantial speedups over established simulators (up to 2.2x vs Shadow, 3.4x vs NS-3, and 43x vs gRaIL) while maintaining comparable performance in large Tor simulations. The work highlights a novel approach to scalable network experimentation for distributed systems research.
