Computer Aided Dispatch CAD spontaneous integration of disparate groups, teams, and reorganization / restructuring based on group rule sets and operationally driven reconstitution during times requiring adhoc grouping to accomplish tasks.
Congressional Directive: "nothing less than network centric homeland security akin to network centric warfare".
The "grail" is to create a single integrated operational picture -- SIOP from cross domain data fusion of N domains / Community Of Interest COI's. Also known as FIOP or Family of Integrated Operational Pictures .
The Heartbeat is a sub protocol of the TCP/IP (Internet) stack that is as old as the internet. It is simply an opportunity in time to gather (state meta) data from internet devices that is then used to adjust the internet infrastructure. The military (having developed the internet stack in the first place (DARPA / Mr Al Gore...); knew that there were unused opportunities in time to move data. They exploited this (to this day) arcane knowledge in developing what is call the "template system" (actually there are 7 - 64 of them as briefed to congress). Protocol gurus (geeks) refer to the heartbeat / beacon interchangably or even together. Point being, to save lives by working together on an apples to apples, oranges to oranges level involves using what opportunities in time that are available to us to CHOOSE / CHANGE our (telecommunications) matrix to either save or not save each others lives in a common, consistent method across systems, networks, agencies, federal, state, local, international / sub-terranean, ocean floor, intergalactic...
GOAL: Enable an international Heartbeat Beacon by following a proven method / process and agreement on III building blocks / common denominators threaded through 4 iterative focus areas to standardize situational awareness (SA), event & alert data exchanges among N complex systems. The result will be a global SA engine providing SA tone & SA as a service. Showing and alerting of a tidal wave that travels 30 miles inland by radius would be helpful. Early warning of an event by intensity by zone (vulnerable buildings within a given radius) would be helpful.
