Modernizing the En Route system presents major acquisition issues to the Federal Aviation Administration FAA. At the present time, efforts are underway to upgrade the En Route system, primarily focusing on the host computer system. Some of the major issues include the following 1 What are the consequences of using different technologies and products 2 How can one assess the use of different technologies Resolving issues such as these will affect the acquisition strategy for upgrading the En Route system. For example, the use of different technologies will influence the design character of the En Route system. This will consequently effect the ability to integrate different components and influence the amount of developed integration code that may be required. Clearly, the ability to optimize the acquisition strategy will have far reaching consequences for the FAA and must be carefully considered. This report addresses the use of different technologies and an architecture trade off approach to a typical En Route system problem. We were requested to consider the problem of resectorization, i.e., the combination and decombination of sectors and fix posting areas during operation of an En Route center. Such capabilities may become desirable for an implementation of free flight. Two technologies have been applied to develop solutions to this problem, namely Common Object Request Broken Architecture CORBA and POSIX.21 Portable Operating System Interface Standard. The former is based on an object oriented model, while the latter is based on a message passing model.
