DONS: Fast and Affordable Discrete Event Network Simulation with Automatic Parallelization
Kaihui Gao, Li Chen, Dan Li, Vincent B. Liu, Xizheng Wang, Ran Zhang, Lu Lu · 2023
Discrete Event Simulation (DES) is an essential tool for network practitioners. Unfortunately, existing DES simulators cannot achieve satisfactory performance at the scale of modern networks. Recent work has attempted to address these challenges by reducing the traffic processed via novel approximation techniques; however, we argue in this paper that much of the slowdown of existing DES simulators is due to their underlying software architecture.
