- SUBJECT: Open Systems Interconnection Protocols
-
- In the 24 August 1988 Federal Register, the Department of Commerce
- published notice of Federal Information Processing Standard (FIPS) Number 146
- to adopt the Government Open Systems Interconnection Profile (GOSIP) Version
- 1.0 for federal government use. GOSIP defines a common set of data communica-
- tions protocols which enable computer systems developed by different vendors
- to interoperate and the users of different applications on these systems to
- exchange information. GOSIP, Version 1.0 dated June 1988, contains the
- requisite information for federal government acquisitions of the Open Systems
- Interconnection (OSI) Message Handling System and File Transfer, Access and
- Management applications in conjunction with several OSI networking technol-
- ogies.
-
- From now until August 1990, the OSI protocols specified in GOSIP are
- adopted as a full co-standard to the Department of Defense protocols which
- provide similar services (MIL-STDs 1777, 1778, 1780, and 178l). During this
- period the DoD protocols may continue to be specified in addition to, in lieu
- of, or as an optional alternative to the corresponding OSI protocols.
- Effective August 1990, the OSI protocols specified in GOSIP become the sole
- mandatory interoperable protocol suite and must be included in all proposals
- for new automated information systems and major upgrades which require net-
- work services. After that time DoD protocols may continue to be acquired in
- addition to the OSI protocols when required to support operational needs.
- OSI protocols which provide additional functionality will be added to GOSIP
- as implementation specifications for these protocols are developed. These
- protocols must be cited in all proposals eighteen months following their
- adoption into GOSIP.
-
- The Department of Defense OSI Implementation Strategy was published
- by the Defense Communications Agency in May 1988 to establish the OSI
- protocols as a military co-standard with the current DoD protocols and to
- provide guidance for implementing DoD/OSI protocol interoperability in DoD
- networks. The Services and agencies should use this document in developing
- information systems requirements. In order to complete the necessary DoD
- wide coordination in a timely manner, DoD components are requested to for-
- ward individual OSI Interoperability and Transition Plans to ASD(C3I) by
- 1 August 1989. The Chairman of the Protocol Standards Steering Group
- (PSSG) will provide guidance regarding common format and content of the
- plans. A progress report is requested from the PSSG by 1 March 1989.
-
- This guidance provides for the interim steps necessary to continue
- progress toward implementation of OSI standards. Final implementation
- details will be provided in a DoD Directive now in process.
