Latham +Request for Comments: 1039 DoD +Obsoletes RFC-945 January 1988 + + A DoD Statement on Open Systems Interconnection Protocols + +Status of this Memo + + This RFC reproduces a memorandum issued on 2-JUL-87 from the + Assistant Secretary of Defense for Command, Control, Communications, + and Intelligence (ASDC31) to the Director of the Defense + Communications Agency (DCA). This memo is distributed for + information only. Distribution of this memo is unlimited. + +Memorandum + + There has been recent rapid progress in the specification and + implementation of computer protocols based on the International + Organization for Standardization model for Open Systems + Interconnection (OSI). The Government OSI Profile (GOSIP), dated 22 + April 1987, contains sufficient information to specify adequately and + acquire interoperable vendor implementations of OSI message handling + and file transfer capabilities. Therefore, the policy on + standardization of host-to-host protocols for data communications, + promulgated by USDR&E memo of 23 March 1982, is modified as follows. + The OSI message handling and file transfer protocols, together with + their underlying protocols as defined in GOSIP, are adopted as + experimental co-standards to the DoD protocols which provide similar + services (MIL-STDs 1777, 1778, 1780, and 1781). These OSI protocols + may be specified in addition to, in lieu of, or as an optional + alternative to DoD protocols, in cases where the current DoD protocol + applicability statements apply. They are designated as experimental + because of the limited operational experience currently available + with the OSI protocols and the limited operational, testing, and + security environment currently defined in GOSIP. Services and + agencies choosing to implement OSI protocols at this time should + carefully evaluate these factors and be prepared to deal with the + complications which may accompany the introduction of new technology. + + It is intended to adopt the OSI protocols as a full co-standard with + the DoD protocols when GOSIP is formally approved as a Federal + Information Processing Standard. Two years thereafter, the OSI + protocols would become the sole mandatory interoperable protocol + suite; however, a capability for interoperation with DoD protocols + would be provided for the expected life of systems supporting the DoD + protocols. + + In order to extend the OSI protocol capabilities and provide + + + +Latham [Page 1] + +RFC 1039 A DoD Statement on OSIP January 1988 + + + interoperability between the DoD and OSI protocols as rapidly as + possible, the following actions are requested: + + a. The Director, Defense Communications Agency, as the DoD + Executive Agent for Data Communications Protocol Standards, + should: + + * Publish by November 1987 the DoD-OSI Interoperability and + Transition Plan. The plan should provide for interoperation of + the DoD and OSI protocols at the application level. A capability + for experimental interoperability of DoD and OSI message handling + and file transfer capabilities should be provided by March 1988, + and a limit operational capability by January 1989. + + * Join the Corporation for Open Systems (COS) as the Department of + Defense representative. COS is a non-profit consortium formed to + deal with testing and other operational issues relating to OSI + protocols. At the request of the Office of Management and Budget, + the Services and other defense agencies should not join COS + directly, but may participate as the agents of DCA on appropriate + COS committees. + + * Coordinate Service and agency participation, in accordance with + existing directives, in groups developing OSI standards, + specifications and operating and management procedures. These + groups include the Government OSI User's Group, the National + Bureau of Standards OSI Implementor's Workshop, the Corporation + for Open Systems, the Manufacturing and Automation Protocol (MAP) + and Technical and Office Protocol (TOP) user's groups, the + American National Standards Institute X3S3 and X3T5 committees, + and the NATO Tri-Service Group on Communications and Electronic + Equipment, Sub-Group 9 (Data Processing and Distribution). + + b. The Director, National Security Agency should assure that the + efforts of the ongoing Secure Data Network Systems program can be + used to provide the security extensions defined as future work + items in GOSIP. + + c. The Services and defense agencies should share the results and + experience of early implementations under the experimental + coexistence policy by actively participating in the groups + indicated above, under DCA coordination. This experience should + be particularly valuable in assuring that military requirements + can be satisfied by the developing OSI standards, specifications, + and procedures. + + This guidance provides for the interim steps necessary to continue + progress toward implementation of OSI standards.
