Abstract
This chapter presents an approach for the design and simulation of embedded networks for spacecraft. The chapter provides an analysis of existing simulation tools for the on-board and local area networks. The authors overview the main abilities of the existing software and then propose the computer-aided design system for SpaceWire onboard networks design and simulation. This CAD system supports the full on-board network design and simulation flow, which begins from the network topology automated generation and finishes with getting the network structure, configuration and parameters setting, simulation results, and statistics – SpaceWire Automated Network Design and Simulation (SANDS). The authors describe formal theories, algorithms, methods, and approaches, which are used to solve general issues that appear in developing of onboard networks. The chapter covers topics of fault-tolerance in onboard networks, discusses routing problems, and approaches to organize deadlock-free routing. The authors propose schedule creation algorithms for STP ISS protocol and consider network simulation issues.
