Where we are…OSA - Evolution of DoD Combat Systems
Logical progress of architectural separation of concerns

What’s the Challenge…
C4I spans a much larger set of systems…
• Not in the same domain • Not managed/funded by the same PM• Leverage different TRFs• Different timelines for integration
and technology refresh cycles
What’s the Challenge…
What makes this hard?
• There isn’t a common interface specification…• Different temporal constraints and requirements… • We can’t standardize on one protocol…• Configuration & implementations vary…
It that is? Something else, at the root?
• It’s the data’s content, context & behavior• It’s an integration scalability problem
What’s been done…
• Where else has content, context and behavior been thoroughly defined?
• Compilers!• Syntax – content• Semantics – context• Operations – behavior
• Consider what’s been done with these rigorous definitions…

What’s been done…
• What made this transform possible?• Machine readable, rigorous, and closed
input, output, and rules specifications• Something like Extended Backus–Naur
Form
• Define “Rigorous”?• Solid mathematical basis &
foundations.• Not just machine readable
• Must be machine understandablehttp://commons.wikimedia.org/wiki/File:Compiler.svg#mediaviewer/File:Compiler.svg

Get to this in a moment….
Current progress…• FACE™ Architecture

Current progress… An Example
• Two message definitions – talking about the same thing, or not?
enum AlarmLevel { GREEN, RED, YELLOW, NO_STATUS, NORMAL};struct alertType : Header { float x, y, z; double set_angle; AlarmLevel status;};
public final class VehicleStatus implements java.io.Serializable{ public String ID = null; public Position3D_WGS84 location = null; public EngineSpeed_RadiansPerSec speed = null;
public VehicleStatus (String _id, ... ) { .... }
}

Current progress… An Example
• Two message definitions – talking about the same thing, or not?
• Demonstrations have shown this to work!• Still more to do, but really exciting.• Interesting with small number of messages, powerful with
1000’s
• ICD Verification & Data Rights • Own the rights things with the right level of detail
Where are we going…
• Pragmatic and Dynamic Interoperability Concerns…
• The ‘data of behavior’ which informs the transformation• Have – Service descriptions and human understandable
forms• Needed – the machine understandable equivalents.
• Its hard, is takes time and there is no magic transform• Take a page from history, it can be done• Have to be rigorous in the rules• We can’t stop current progress
