The Project Trailblazer System Architecture

The Project Trailblazer system architecture consists of functional blocks that acquire data (inputs), control equipment (outputs), store data, and distribute data. Figure 2.4 shows these blocks and their interconnection. Project Trailblazer's input, output, and data storage blocks exist on a private network to protect access to them. The data distribution block provides access to the stored data from a public network. Remember that a system architecture only specifies functional blocks and their interconnection. The design phase addresses implementation details, such as component specifications and selection. The Project Trailblazer architecture, although simple, provides the framework for design activities ...
