Elvis: A Highly Scalable Virtual Internet Simulator

Elvis is a highly scalable virtual Internet simulator that can simulate up to a hundred thousand networked machines communicating over TCP/IP on a single off-the-shelf desktop computer. This research describes the construction of Elvis in Rust, a new memory-safe systems programming language, and the design patterns that enabled us to reach scalability targets. Traffic in the simulation is generated from models based on user behavior research and profiling of large web servers. Additionally, a Network Description Language (NDL) was designed to describe large Internet simulations.
