Levine, Deputy Director Defense communications Engineering Center, DC- k, 1860 Wiehle Avenue Reston, Virginia 22090 It was enjoyable talking with you on 30 ;July. I always appreciate an update on what is going on at L)CvA. In my present business, I have virtually no contact with anyone from D CA, although I do get an occasional bit of news through As r explained to you on the phone, we are undertaking the development of a large stand-alone file building, storage and retrieval system. Chile the design concepts are not firm at the present time, it is clear that we will be pushing the state-of-the-art in several areas : rapid text search; docu- ment retrieval; and, telecommunications. The cost tradeoffs involving telecoxmunications alternatives might well be the governing factor in selecting a final design. It is in this area that I thought we might get some useful ideas from your people. The system will be designed to accommodate up to 2000 remote interactive terminals which will be connected to the computer environment through a telecommunications network. The terminals could be limited to telecommunications at a rate of about 9600 bits/sec., or the design could call for the ability to remotely view documents at the terminal, which would require wide-band digital telecom munications or possibly video links. The computing environment could consist of a very large central processor/mass storage system, or -vie could choose a distributed system. If we go the distributed route, the telecommunications network will involve considerable switching. The majority of the terminals will be located in our headquarters building. ,4e have a tight schedule which will necessitate pinning down most of the basic design choices within the next year. At the present time, we are trying to learn more about what is going on in the telecommunications area which may he ap- plicable to our problem. It occurred to me that people in the Defense Communications E Engineering :enter would probably have a good overview of activities in this area, both in govern- ment and industry. If this is the case, we might be able to save some time if we could talk to your people.

Wideband transmission/multiple:xing/sswitch-iing systems for servicing a highly concentrated user environment. Distributed processing systems. C. Packet switching. d. Error handling in communication nettiworks. STATINTL If you wan s uss ssible agenda topics further, you can call me on is the project director responsible for the s:as es e e t mentioned above. If you feel that you are able to give us some advice in these areas, I would like to arrange a meeting sometime in late September 1976. Our group would consist of 6 to 8 people who are skilled in the design and development of large-scale information processing systems. Please let me know whether you think this meeting would be fruitful and, if so, what date would be convenient for you. Sincery STATINTL Clirforc o. may, .sr.
