Experiences in a distributed, real-time avionics domain-Weapons System Open Architecture

Weapons System Open Architecture (WSOA) utilizes a distributed object computing foundation as a "bridge" to enable communication between disparate real-time systems in the redirection of strike assets. This open systems "bridge" connects legacy embedded mission systems and off-board C3I (command, control, communication and information) sources and systems. WSOA will establish the potential gains in warfighting capability due to the enabling technologies of collaborative planning, information mining, and adaptive embedded resource management. This paper focuses on the experiences and lessons learned in the WSOA demonstration program with CORBA middleware, pluggable protocols and Quality of Service (QoS) enforcement, management and verification.
