Embedded computer software loader/verifier implementation using a hardware and software architecture based upon best practices derived from multiple spiral developments and the joint technical architecture

The focus of this paper is to examine the concept of utilizing commercial-off-the-shelf (COTS) products and interfacing the products to design and implement a solution to the diverse requirements of ground support equipment for military aircraft. The challenge of sustainability during the life cycle of specific ground support equipment is examined from multiple viewpoints. The decisions and resolutions associated with using and supporting COTS products is also presented. During our examination, existing products are described, an architecture for each implementation is derived, and the strengths and weaknesses of our solution are explored. Finally, a root cause analysis for the problem of COTS interface architectures implementation in the support equipment environment is presented.
