Heafner [Page 8] RFC 164 Minutes of Network Working Group Meeting May 1971 o SDC not meant to be a general service; will allow 1 to 4 users; can use Adept to run a job. o Experimentation plans include: 1) Voice I/O will use Net to communicate with speech researchers (will respond to specific programs only) 2) Eventually graphic I/O 3) Man/machine synergism 4) Network data management 5) Network resources Notebook use and update. ILLINOIS-CAC o IMP works. o Will use B5500 on campus since B6500 doesn't work. o Will link to PDP-11 at Paoli for I4 software development -- not a general link for everyone. AMES o Probably will be two separate nodes ILLIAC and 360/67. o Plans are in rumor stage. o Plan TIP by end of summer to gain access to I4 simulator. o Duplex 360/67 will be regular host node. o Are looking for an NCP implementer. o Will use other services; laser store and UCSB. o Their general research includes an interest in Network accounting and management. o Will go onto Net as soon as possible to ILLINOIS. o Will go on via TIP if it can support two nodes. o Will define Net protocol for interactive graphics for I4. o Plan to get on Net before I4 comes up.Heafner [Page 9] RFC 164 Minutes of Network Working Group Meeting May 1971 CCA o CCA is responsible for data computer project. o It is special purpose computer with large storage device. o Data computer (PDP-10 and laser memory) should be viewed as one black box. o Will have two ports -- high-speed to I4 and low-speed to IMP. o Data language and data will pass over ports. This will include requests of files and portions of files, update, manipulation, and transformation of data. It will not include number crunching. Only access to the laser store will be through the black box data computer. o Hardware and communications are specified. o Data computer services are beginning to be defined, (600 questionnaires were sent out, 10 responses were received). With regard to services please call Dick Winter on (617) 491-3670. Dick wishes to hear from any potential user. o Laser store is one trillion bits of on-line storage packaged in 40 packs containing 10 mylar strips each. Strips are kept in a carousel that can be rotated and mounted in 10 seconds. Access to any track is a maximum of 400 ms. o Laser will arrive at CCA in early 1972 and move in late '72. Services to laser while located at CCA will be offered. o CCA will send out plans (as feasible) as RFCs. CASE WESTERN o Hardware has been built (PDP-10) and starting to test it. CARNEGIE o Hardware includes PDP-10 240K 36-bit words, TTY, etc. o Currently using DEC monitor. o Will modify Harvard's version of the monitor.Heafner [Page 10] RFC 164 Minutes of Network Working Group Meeting May 1971 HARVARD o Hardware includes PDP-10 with PDP-1 as graphics devices handler. o Hardware is up, talking back and forth. o NCP (RFC #107) for PDP-10 will be completed by the end of the month. o PDP-10 has 48K 36-bit words; expect more core after July; will then make NCP resident. o Interested in file transfer, graphics, extensible languages, experiments of distributed processes. IBM RESEARCH o IBM will buy an IMP, now negotiating it. o They are designing new concept of Networking. o They will become an active node with either a 67 or a 91. The candidate 91 now has 300-400K. RADC o TIP is scheduled for delivery in October. o They will provide local access to the SRI on-line system. o They are interested in the July graphics meeting sponsored by MIT. (Al Vezza) MIT DM AND MULTICS o GE-645 runs MULTICS: PDP-10 is for dynamic modeling of graphics systems. o NCP (RFC #107) on PDP-10 by end of week. o Logger on PDP-10 available by 15 June. o NCP (RFC #107) available on MULTICS by 11 June. o Logger and TELNET available on MULTICS by first week of July.Heafner [Page 11] RFC 164 Minutes of Network Working Group Meeting May 1971 o They have been conducting file transfer experiments of simplified ASCII transfers (not RFC #114). o Interests include: 1) File transfers 2) E & S processing to IMLAC and ARDS formats 3) DRS service. LINCOLN o Three connections are planned. o 360/67 has NCP, logger, TELNET, and some file transfer protocol. o TX-2 NCP is being developed. An interim NCP is working with file transfer experiments, error detection and correction. o They are experiencing hardware difficulties with the third connection. o 360/67 has been running NCP (doc. 1) and a TELNET-like protocol since 1 March. UCLA and Rand have logged in. The TELNET-like protocol supports ASCII and EBCDIC. o NCP (RFC #107), TELNET, and logger will be operational on 67 by 1 July. BBN-NCC o NCC is responsible for maintaining the subnet and interfacing with Honeywell and AT&T. They are planning a mechanism for repair of the Net from their homes. The subnet has experienced a 98% up time. o An operational 316 version of the IMP has been hooked into the Net since February. It is a production item at 1/2 cost of 516; the IMP programs are identical. o The 316 will be incorporated into the TIP. The multi-line controller has been fabricated and is being debugged. A common language for the TIP has been developed. TIP will be delivered to NASA Ames on 1 August. The TIP will handle 64 lines up to 19.2K bits. BBN is still shaking down the kinds of terminals that will be compatible (will be bit serial at least). They are working with sites to determine terminal requirements.Heafner [Page 12] RFC 164 Minutes of Network Working Group Meeting May 1971 o The resource notebook has been compiled and distributed. Twelve of 19 sites are included in the notebook. SDC has since reported. Stanford, SRI/AI, MIT/DM, UTAH, Carnegie, LL/67 have not provided an entry. BBN again made a call for responses and asked that each site stay up-to-date. A comment was made regarding the Notebook that a mechanism is needed for a) date of information, b) complaints of information, c) reporting that advertised procedures do not work. o TIP delivery for the rest of the year is to the following five sites: Ames, Mitre, Rome, ETAC in Washington, D.C., and NBS. o BBN has been studying performance of Network to learn ways to improve it. An earlier Rand RFC reported a very low rate for a total Network experiment -- Rand re-ran the experiment to examine just the subnet performance and reported the subnet rate to be in the 13-15K bit range for that test. MIT/DM has reported a 5KB rate that will be examined further. BBN made a general offer to the Net community to phone NCC in the event that such measurements are taken and low data rates are discovered. o The BBN-Honeywell relationship is a straightforward maintenance contract that includes P.M. and other problems which arise. BBN stated that a 24-hour delay in service would be unusually long. BBN would like to be kept informed of views and opinions of the Honeywell service. BBN asks that each site keep a maintenance log and copy it to Marty Thrope at BBN. BBN/TENEX (reported by BBN/NCC) o BBN has a three-host IMP that includes NCC and two PDP-10s. One 10 is for operational use, the other for experimentation. o Software for the PDP-10 is TENEX. o They are interested in getting involved in Network experimentation. MITRE o Expect TIP delivery in September. o Now using PDP-10 at BBN.Heafner [Page 13] RFC 164 Minutes of Network Working Group Meeting May 1971 o Will work on sample data management system using UCSB file storage. NBS o Expect TIP delivery in December. o Have selected PDP-11 as host; ready by December. o Will build from the U. of Illinois operating system. o Contemplating attaching their UNIVAC 1108 to Network. o Will provide experimental access to Network for services: 1) measurement (performance) 2) graphics 3) personal communication 4) lab automation 5) support NBS with services appropriate 6) provide local hardcopy from PDP-11. ETAC (Environmental Technical Application Center o ETAC, located in the Washington area, is a branch of Global Weather Service. o Air Weather Service in Omaha, Nebraska, has seven 1108s providing weather data; one will be connected to Net to provide daily weather information to ETAC in Washington. o ETAC has 1401 and 7040 in Washington to produce summaries for longer range use; the 7040 may go on the Network. AIR FORCE SITES (reported by ARPA) o To export technology to other regions, two Air Force sites (Oklahoma City, Oklahoma, and Sacramento, California) will temporarily join the ARPA Net to talk only to each other in an operation to parallel their AUTODIN connection. If it materializes, they will run for the first six months of '72 but probably won't continue. The motivation is to examine the Net ideas for developing a wholly autonomous network in three or four years.Heafner [Page 14] RFC 164 Minutes of Network Working Group Meeting May 1971OTHER REPORTS DEPT. COMM., CANADA The Canadian Government wishes to optimize the use of all computers in Canada. They now have a banking network. They are interested in a small net for universities. Their largest problem is the size of the country in relation to the sparseness of population. U. OF CHICAGO The University of Chicago has no current time schedule but they have definite ideas about what they wish to accomplish and they are seeking funding. They are applying to NSF to support a local net on campus for lab automation. They have good people and good equipment; the idea is to make it coherent. Their interest in the ARPA Network is to make shared software available to their people and to a limited extent, make local services available to other ARPA nodes. Their proposed host is a PDP-11 to the mini computers and a second host (PDP-10) as a big software engine to make data available to the mini computers. The PDP-10 and PDP-11 will perhaps be linked together. They also expect to get a TIP to provide remote number crunching for their people. UNITED KINGDOM They have proposed three main machines and three terminal nodes. They have in mind the 906A, approximately the 360/75 in power. Their Post Office also has plans for a digital network in the distant future. MERIT MERIT-UNIV. MICH. Most of the bugs are out of the hardware. Most of the software is written.Heafner [Page 15] RFC 164 Minutes of Network Working Group Meeting May 1971 Will have PDP-11s by the end of the summer that are capable of transmission from one to another. They will need and are now studying a TELNET-like protocol. They are concerned with orderly communication of the two processors; will later become concerned about process-process communication. EDUCOM EDUCOM involves 100 major universities including most of those now in the ARPA Network. For two years, they have been running a network without wires. They assume the ARPA Network can resolve the technical issues. They are looking into marketing, contracts, documenting, etc., for running the network. They have conducted a survey of 70 universities, polled about their interests in the ARPA network: 60 of 70 are interested, 14 have money and are ready to become sites. RAYTHEON They will access the Net through the four Boston nodes. Their interests include: 1) experiments of file transfer conversions. 2) indexing behavioral data to allow one to search an index to see if the body of data of interest is within the Network.MISCELLANEOUS TOPICSGraphics Al Vezza will host a July meeting of a small group interested in Network graphics. The price of admission is a sincere interest, working background, and a prepared talk.NCP Protocols A new official document will replace document 1 and RFC #107; implementation should not be held up because of the absence of this new document. The long range protocol committee chaired by Carnegie has been disbanded.Heafner [Page 16]⌨️ 快捷键说明
