The WW Technology Group (WWTG) offers capabilities in the design of high performance and dependable systems with design tool support. The firm's approach is based on middleware (software that acts as a bridge between an operating system or database and applications on a network) that integrates Consumer Off-The-Shelf (COTS) components into a dependable system. WWTG has shown this approach works with heterogeneous versions and thus facilitates iterative design solutions that can be used to rapidly explore design alternatives, support technology refresh during the system life-cycle, and integrate diverse systems into a system-of-system architecture. The capabilities are scalable with respect to size, performance, and dependability. The footprint and associated overhead is customizable to reduce the footprint and overhead based on requirements. WWTG has helped customers, including DoD (Air Force, Navy, DARPA), NASA, and prime contractors address key challenges and develop effective solutions. The WW Technology Group's fault-tolerant architecture has become the basis for the Ship Control System for the Virginia Class Submarine that provides real-time x-by-wire capabilities. WWTG's robust fault-tolerant designs are based on formal distributed systems theory, which produces analyzable designs that avoid or contain system modes that lead to single-points of failure.
