- EXERCISING THE ARPANET
-
-
- Questions
- ---------
-
- 1. Can a technically competent person, initially uninformed
- as to network operation and naive as to the capabilities
- of various time-shared terminal systems attached to the
- Network, be able to develop problem solving competence
- at server sites on the ARPANET?
-
- 2. What inherent user problems exist that complicate such
- adaptation?
-
- 3. Once proficient in the use, what aspects of the various
- sites limit the usability and what modifications should
- be considered at both server and user sites to meet
- various needs?
-
- 4. Should a user select a given site for composing and
- editing all of his files for subsequent transfer to
- other sites for processing or should he learn to compose
- and edit at each of the sites doing his processing?
-
- 5. What are the problems in starting cooperating processes
- at several sites? How does a user control such
- processes?

- Obtaining the Answers
- ---------------------
-
- Under the direction of UCSB Professor James Howard, a test
- group of 14 graduate students was formed to pursue the questions
- above, and any other aspect of ARPANET operation that they might
- uncover.
-
- The test group has been given access to the 16 console On-Line
- System classroom in the E.E. Department at UCSB. The 16 consoles
- produce graphic and alphanumeric displays and are tied into the
- UCSB Host 360-75 which gains them access to the network. Old
- style Culler-Fried keyboards are being used which provide a
- limited key set Jim White has managed to program around most of
- the protocol problems brought about by these keyboards, but some
- still remain.
-
- Seminars were given to the test group to familiarize them
- with software and hardware aspects of the ARPANET, the local NIC
- file has been made available to the group, and the group has been
- allowed to sign onto the Network to pursue any available system.
-
- Following the initial period of two weeks, during which the
- group developed some familiarity with the network, the test group
- has been divided into working groups with emphasis as follows:
-
-
- Patric Timlick } BBN-TENEX
- Dave Stearns } BBN-TENEX B
-
- John Pickens } SRI-ARC (NIC)
- Doug Beaubien }
-
- Dave Whittington }
- Richard Haraguchi } MIT-Multics
- Maria deGraaf } MIT-DMCG
- Richard Melton }
- Su Sung Won }
-
- Ronald Varekamp }
- Jeoff Benson } UCLA-CCN HARV-10
- Hasan A. El. Hasan } UCLA-NMC UTAH-10
- George Engelberg } RAND-CSG LL-67
- Rodney Skinner }

- Some Initial Results
- --------------------
- The first real encounters with the ARPANET at large produced
- a series of questions and comments. Test group comments are
- itemized below with additional comments by the author {In braces}.
- We plan subsequent reports on a periodic basis.
-
- 1. We find that we need further information about access
- to the NCPs at various sites. User manuals from the
- sites might provide this. {Site response is solicited}
-
- 2. We sometimes cannot sign into UCLA-NMC directly from
- UCSB, but can do so readily by way of BBN. {Protocol?}
-
- 3. After running a Fortran or PL-1 program at some net
- location we can only display the results on our consoles
- but cannot store them as files. {UCSB programming need?}
-
- 4. When communications break down how can a user be
- assured that he is logged out of some remote site?
- {Need for automatic Log-out?}
-
- 5. How do we make contact with programmers at other sites
- to develop cooperative programs for file transfer, etc?
- {Jim White?}
-
- 6. Is there a best time of day for operation at each site?
- Should contact be made with the site operator prior to
- user sessions? {Server sites please comment}
-
- 7. UCLA-NMC has assigned a separate user identification
- for test group use. Would other sites prefer to do
- likewise? {Comments?}
-
- 8. Is there information regarding uses made of the
- various time shared systems by internal users at each
- site? Does a bibliography exist to allow contact
- with such users? {Check the Resource Notebook}
-
- 9. MIT-DMCG and BBN provide very good user service,
- especially the site survey. Also these sites have
- good responses to define events. Can UCSB provide
- local users with similar information? {Jim White?}
