US Navy Ships To Be Built With Self-Correcting Infrastructure

CRA received a contract from the US Navy to develop a Self-Healing Adaptation Infrastructure for Loss Tolerance (SAIL). Charles River Analytics and George Washington University (GWU) collaborate on SAIL.

A Navy ship uses a complex, interdependent network of computers, including servers, sensors, and control systems. As a result of a damaged computer running mission software, other ship components must take up the slack.

So if an enemy missile destroys the system that processes radar data, the radar sensor hardware may still work. The ship equipped with SAIL can self-heal by adapting its network of remaining hardware and software resources to perform radar data analysis, replacing the function which has been lost.

SAIL recognizes when a processing node goes down on the ship and distributes the capability lost. A single node may not have sufficient computational power to run a second complete application, so SAIL allows the application modules comprising the lost ability to be executed on separate, coordinating nodes.

"SAIL's main advantage is that it's decentralized, so platform capabilities can remain available if something goes wrong. Additionally, SAIL allows analysts to track resource allocations, so they can determine when low-SWaP compute nodes should be added to cover possible outages, or resources should be removed from underutilized components."
