I've heard a lot lately about the OSI international standards, and even some rumors that the DOD may drop TCP/IP in favor of the OSI protocols, when layer 4 (network) is approved as an international standard. Given that only two layers (that I know of) have been approved (session and transport), I wonder how many companies have implemented, or plan to implement, the OSI international standards for higher levels? It's probably a given that CSMA/CD and Token Bus will be approved, so that adds more clout to the OSI standards. If you, yes you, had the choice today, would you implement TCP/IP, or go with the ISO OSI standards for layers 3 and 4? I'll summarize and post all responses I receive.

This is a reproduction of a memo written by Donald Latham of the office of the Assistant Secretary of Defense on the subject of DoD's evaluation of the TP-4 protocols. ASSISTANT SECRETARY OF DEFENSE Washington, D.C. 20301-3040 MEMORANDUM FOR DIRECTOR, DEFENSE COMMUNICATIONS AGENCY SUBJECT: National Research Council Report on Transport Protocols for DoD Data Networks [RFC 942 is] ... the final report on "Transport Protocols for Department of Defense Data Networks" from the National Research Council (Board on Telecommunications and Computer Applications, Commission on Engineering and Technical Systems). The report recommends that DoD immediately adopt the International Standards Organization Transport Protocol (TP-4) and Internetwork Protocol (IP) as a DoD co-standard to the current DoD standard Transmission Control Protocol (TCP) and IP and move ultimately toward exclusive use of TP-4. Whenever international standards are available and can be used to support military requirements, they will be implemented as rapidly as possible to obtain maximum economic and interoperability benefits. However, TP as a proven commercial offering is not available at this time. The progress of TP will be monitored carefully and once commercially available, TP will be tested and evaluated for use in military applications. In order to insure that DoD is in a posture to evaluate TP once it is in wider use in the commercial sector, request you initiate the following actions: (1) develop the DoD military requirement specification for TP to insure that industry is aware of DoD needs as TP is commercially implemented. (2) insure that appropriate advisory representation is provided to commercial standards working groups that are currently refining TP under the auspices of the National Bureau of Standards. (3) insure that the DCA protocol test facility can accommodate TP testing as required when commercial implementations are available. (4) develop a transition strategy for Option 2 of the report to include estimated resource requirements. (5) evaluate the detailed recommendations presented in the Report (pages 61-64) as they apply to Option 2. Donald C. Latham cc: NBS, Mr. Bob Blanc

ANSI (American National Standards Institute) sells copies of the various documents. They have a list called "Current ISO/TC 97 working papers and draft standards." The current list shows around 60 documents available, with another 20 or 30 due June 1. The average price is about $15 each, and there's a 7% shipping charge. ANSI is at 1430 Broadway, New York 10018. They have very capable people answering the phone, which is 212/354-3300.
