Combat System Distributed Operating System

1Commercial standardization activities are currently developing interface standards for distributed processing systems that support software portability and interoperability in an open system environment. A key element of open system implementations is the operating system for the distributed environment. The purpose of this Phase I task is to evaluate available commercial products and identify likely candidates for future implementations, and to develop the basis for detailed specification of distributed operating system service requirements and performace characteristics. The Navy can effectively benefit from commercial development by choosing appropriate distributed operating system service requirements and performance characteristics that are in conformance with the evolving commercial standards, yet can satisfy Navy requirements. The work proposed undr Phase I will : (1) develop the basis for quantitative determination of combat system distributed operating system performance requirements; (2) develop the basis for specification guidelines for a combat system distributed operating system; and, (3) prodvide an unbiased, objective engineering evaluation of avilable commercial distributed operating systems which would have potential application to shipboard combat systems in the 2000 and beyond.
