Future space and military applications, such as, NASA space exploration missions, will require high-bandwidth but dependable avionics architectures for on-board mission-critical processing and aggregate information exchange among subsystems. This paper is to present a design process that we at Honeywell Labs have used to design next generation high-speed avionics with open system architecture. The process begins with review of prior arts and collection of voice of customers. Candidate open source technologies are then identifled by a Six-Sigma based study, followed by a failure mode and efiect analysis to select and deflne a proof-of-concept system architecture. The proof-of-concept architecture is evaluated, validated, and reflned using OpNet Modeler simulations. In the context of this paper, we use IEEE-1394b based avionics design as an example to describe this process. |
