Abstract : The Communications Processor Operating System (CPOS) effort is one program of a multiple program effort whose purpose is the development of a Unified Digital Switch (USD) for strategic communications. This switch will have the capability to perform circuit, packet and store-and-forward message switching in an integrated communication complex. The Communications Processor System (CPS) will control the switching node and will be supported by an operating system called the Communications Processor Operating System. In particular, multilevel communications security conforming to DoD requirements represents a difficult problem for the CPOS and requires solutions which are on the fringe of the current technology. In addition, the need for high reliability is a cause of concern because of the inexact science of software technology. These concerns have resulted in heavy emphasis being given to Tasks 2, 3, 6 and 7. A specification has been prepared as a stand-alone document suitable for the next stage of contractual or in-house development of the CPOS. (Author)
