Live network simulation in julia: design and implementation of LiveSim.jl

Abstract

An architecture for interactive, notebook-based ns-3 simulations in the cloud is proposed. A prototype implementation of an example study for IEEE 802.11p inter-channel interference is developed as a test-case, using direct integration of ns-3 components with Jupyter via Julia's C++ support. This shows that flexible animations with advanced visualization of live ns-3 simulation results can be setup quickly. Although the system appears complex, the benefits of ns-3 as fast and flexible discrete event simulator complement Julia's scalability in numerical computing and Jupyter's versatility on the Web and provide supporting evidence of LiveSim as a promising direction for multi-modal, reproducible network research.
