Open System Interconnection (OIS): NASA Program Communications of the Future

Abstract

Open Systems Interconnection (OSI) standards are being developed by the International Organization for Standardization (ISO) and the Consultative Committee on International Telephone and Telegraph (CCITT) with the support of industry. These standards are being developed to· allow the interconnecting of computer systems and the interworking of applications such that the applications can be independent of any equipment manufacturer. Significant progress has been made, and the establishment of government OSI standards is being considered. There is considerable interest within NASA in the potential benefits of OSI and in communications standards in general. The OSI standards are being considered for possible application in the onboard Space Station Data Management System. The OSI standards have reached a high level of maturity, and it is now imperative that NASA plan for future migration- to OSI where appropriate
