The subject of this paper is centered on presenting a Vehicle Network (Data Bus/Protocol) Selection process for a Common Software Architecture for Ground-based Vehicle Systems. Vehicle network data buses/protocols are analyzed/evaluated and selected to support the real-time requirements for the architecture. It is through data research, simulation and evaluation of architecture models that today's Crusader Combat Vehicle Program's RTCOE (Real-time Common Operating Environment) Software Architecture can be made THE BEST common software architecture for all Combat, Tactical and Utility Ground-based Military Vehicle Systems.
