Middleware for Portable Avionics Software

"The project goal for Phase 1 is to define an approach for a portable avionics software platform that facilitates re-use of avionics applications from platform to platform, meets stringent real-time performance requirements and incorporates standardizedinterfaces and services. The standardized interfaces and services to be supported will include, but will not be limited to, CORBA interfaces and services. Over the last several years CORBA and its services and facilities have evolved to the point wherethey have the potential to be used as a distributed object computing middleware component for avionics systems. CORBA was selected as the baseline distributed object computing standard because of its wide acceptance in both commercial and military systemsand recent work performed on real-time and fault tolerant CORBA. This project focuses on methods for efficiently integrating standardized services into an avionics environment while maintaining high levels of performance and determinism and support formulti-level security. These goals will be achieved through adaptive middleware techniques that stress performance, portability, extensibility, and configurability. A multi-phased commercialization program is defined for the selection, demonstration, andtransition of an approach for middleware isolation layers for open architectures for critical applications. The promise of middleware based system engineering is substantially improved reuse
