Modular End-to-End System Simulation

SimBricks

Enable end-to-end system evaluation when hardware testbeds are out of reach through modular combination of existing simulators for different components.

SimBricks is a simulation framework that enables full end-to-end evaluation of modern network systems in simulation. Our primary aim is to to enable network systems research and instruction — from rapid prototyping to meaningful performance evaluation. SimBricks modularly combines and connects multiple battle-tested simulators for different components: machines (e.g. QEMU, gem5), hardware components (e.g. Verilator, Tofino, FEMU SSD), and networks (e.g. ns-3, OMNeT++). SimBricks assembles multiple instances of these simulators into simulated testbeds capable of running unmodified full system stacks, including applications and operating systems such as Linux.
