RFC 302

EXERCISING THE ARPANET 💖

okay bestie, the title block first 🎀 This is NWG/RFC #302 (also NIC 9074), written by Roland F. Bryan of the UCSB Computer Research Laboratory on 8 February 1972. The original doesn't say what category or status it has, and it doesn't list anything it obsoletes or updates. 🧚

Questions ✨

Okay so the whole doc kicks off with five big questions, and they're iconic 👑

1. Can a technically competent person, who starts out clueless about how the network works and naive about what the various time-shared terminal systems attached to the Network can do, build problem solving skills at server sites on the ARPANET? 🧠
2. What inherent user problems exist that make that adaptation harder? 💀
3. Once you're proficient, what aspects of the various sites limit usability, and what changes should be considered at both server and user sites to meet different needs? 🛠️
4. Should a user pick one site to compose and edit all of their files, then transfer them to other sites for processing? Or should they learn to compose and edit at each site where they do their processing? 🤔
5. What are the problems with starting cooperating processes at several sites? And how does a user control those processes? 🎮

Obtaining the Answers 🔍

this part is giving research lab era energy 🦋 Under the direction of UCSB Professor James Howard, a test group of 14 graduate students was formed to chase those questions, plus any other ARPANET stuff they might stumble on. 💅

The test group got access to the 16 console On-Line System classroom in the E.E. Department at UCSB. The 16 consoles make graphic and alphanumeric displays, and they're hooked up to the UCSB Host 360-75, which is how they reach the network. 🖥️ They're using old-style Culler-Fried keyboards, which have a limited key set. Jim White programmed around most of the protocol problems those keyboards caused, but a few are still around. 😭

The group got seminars on the software and hardware sides of the ARPANET, the local NIC file was made available to them, and they were allowed to sign onto the Network to explore any system that was available. 🌸

After the first two weeks, when the group got a feel for the network, they were split into working groups with these focuses:

     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 big ARPANET 💜 produced a bunch of questions and comments. The test group's comments are listed below, and the author's extra comments are in {braces}. They planned to put out more reports on a periodic basis. 🎀

1. We need more info about access to the NCPs at various sites. User manuals from the sites might cover it. {Site response is solicited} 🙏
2. Sometimes we can't sign into UCLA-NMC directly from UCSB, but we can do it easily by going through BBN. {Protocol?} 🤨
3. After running a Fortran or PL-1 program at some net location, we can only display the results on our consoles. We can't store them as files. {UCSB programming need?} 💾
4. When communications break down, how can a user be sure they're 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 before user sessions? {Server sites please comment} 🕐
7. UCLA-NMC assigned a separate user identification for test group use. Would other sites prefer to do the same? {Comments?} 🆔
8. Is there info on how internal users at each site use the various time shared systems? Does a bibliography exist so we can contact those users? {Check the Resource Notebook} 📚
9. MIT-DMCG and BBN provide very good user service, especially the site survey. These sites also respond well to defined events. Can UCSB give local users similar info? {Jim White?} ⭐
