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.
