[ aarea wlth WDK (1 549 4,) ~hat the first step In p lannin G ongoing Journal evolu~ion is to collect toge ther In one document and cateQ;orize the su~"ustlons which have been made in the past . ThIs will require a search back throu8 h past Journa l submissIons ot the last two yers or 90 and should be done. My g uess Is that It wilL take about 3 days fo this t as k. Then workln" with JCN they should be orrlered according to needs perceIved to launch the utiLity and support the ARPA O~~ice. In addi~ion to the Ideas { sug~Bsted In (145 62 ,) additionaL ne eds are ~o r unrecorded dialog , taster delivery, being able to splIt the distri b ution list Into primary receivers (the ones likely to take action) and thos~ rec~lvlng copies to keep them Lnrormed and indication in the delivered cItatJon whether you are receivIn g the Item as a primary receiver or as a "cc".

Data Processing :for the Social Security Administra.tion

M.r . lIanna app r oached the Institute as a who l e, seek ing leads for problems In developing a new Co mpute r-Center complex tor the SSA . Be described hIs situation, plans , and prob1.ems, be.fore lunch, to the foltowlng: Bart Cox , Dave Brown , Jack Bialik, Joe GriPI)O (SR[ Manapement Science), Dick Watson , Paul Rech , and me . Lunch with Rart , Joe, ana me. Nature o~ his pre- lunch description was flS fo ll o'tll's :

The Soc ial Security Administration has some 23,000 employees in the fie ld, distributed around the U.S. , 12,000 staffing payment sta t ions , and the rest (7) at their h eadquarters in Ba lti more , Md. has some 9 , 000 types. (Note: number s .. )

Under Mr. Hanna , the Bureau of Data Processing people, 2 , 000 0'1 WhIch are computer systems don't depend upon 'the accuracy of 'the above

Their data processln~ load is ex'tremely large : like eve r y n1 g ht they moun t some 10,QOO reels of ma g neti c tape. Very large archival store , 250 , 000 reel s . And there is a very signi:ticant conce.rn 'for the physical security of their data.

Expects a mass- storage n eed 01 t ra m 20 to 50 billion bytes In the :f~rseeable tutur e . Doesn ' t assume that mi.'L&:netlc tapes can cope wlth that need, but he doesn't see them disappearin g tram their sce n e for quite a while.

Current machine complement: two 1108s, 370/65, one ~7 0/165 (one more coming),

twelve 360/659, one and thirty 360/30s.

Apparen tly they are users ot 18M's ASP techinques (Assistant Support Program) , where all o r part of one computer is used to run tL program that controls the scheduling of a cluster of machines (he r e:forr r ed to each cluster as an "ASP Kludge"). For instance, haLf of ~ 360/65 controls a cluster of three other 65s and the other half of the controller 65.

Congress has Just added significantty to th e jr data- processing commltment by manda~i n g to them ~he DP support :for the recently passed Family Assistance Plan's aid to the aged , blind, and disabled .

One aspect o f thls new burden is that tlley must support (by next January) 700 terminals dlstributed around 'the coun try -- mos t of whlch will be used for butch [/ 0; a "small number" or real-time support.

In such very-large-scale operatlons, the management problems tire .found to increase more than lInearLy with size.

He knows that their system is outl'loded, bu t points out that It is much t oo massive t o consider a sin g le-step replacement by a new system; they must chang e by evotutlon . He mentioned that he wIlt have a '!redesi g n g roup!1 established ~or this purpose .

Evolution is consistent ly hampered by their a l ways being behind, always ope r ati n g on a "crush baais " to g et thln ~ s o ut the door . When the Inco~e £or so many recipients' Is dependent upon their e~forts, tbey can'~ shut down, ever.

He wunts to have u n approach ~hat can ~ind them ready by 2000 AD for both the antiC i pated technolo g ical capabILItIes and the extremely larg e , ce n~ralized data p rocessing load tha~ seems Inevitable (and uni mo g inaeable).

The prilllary problem In his mind , :for bis a p proactl to S RI, was one whose nature was more a matter 01 the architecture o:f b~ildin g s rather th an o~ DP systems: most of tbe authoriZation has been passed for his be g inning in Center buildin g . He hoped to be able

19 74 to build a Computer to establ ish a

f~nctio n al , g eome tric concept that would make their subsequent DP-system operation and evolution much easier .

He described one possib ilIty that he is considerin g ; it would be a cy~indrical building , hal1 underg r ound (provIdin g physical Securit y for some parts 01 their ope r ation) a n d hat~ abo ve g r ound . An inner cylinder would house key 'facilities-operational mana g ement; an intermediate cylinder would h ous~ the equipment , and "the o -uter cylinder most 0'1 t h e r est 0:1' the st a fi' .

He pictures on adv antag e for the inner-c ylInder management operatinns to have vertical mobility, to set up at floor levels where par~icutar equipment was hous ed -- assumin g that evolution hath in equipment complement and in dynamic chang es in the loading 01 different clusters would require such mana g ement mobility.

At lunch 1 made the ~ollowlng observations on the posslblle Impact on hoth his computer-system desl M" and his new-Center ef"chitecture 1rom use of packet-communjcation technolog y:

A special-purpose packet-communication network could interconect user terminals with nodes o~ processor and storag e

r esources, much as the ARPANET now does. 28

Perhaps purposely build theSe stora g e/processor nodes in distributed gites! advantag eous ~rom point o~ physical securIty, perhaps; also enables eusier expansion by removing the probllllS of having to pre-p'lan the sing le central structure adequately, of risking running out of s p ace, o~ runnin g into awkward clustering binds, etc. 2b

DperatIona~ reLiability would seelll ent\anced, since thjs mode of interconnec~ing nodes ot proces s or, storag e, and I/ O equipmen~ would be maximallLy ~lexible 10r reconflg urlng the distribution of processing and the ~lo. of data. Evolution 0 1 his whole assembly 01: equlplllen-t and processes should be much enhanced by this same -freedom from g eometrIcal constrain1. s .

I brought this possIbiLIty up to him several tjm~s during the afternoon, too. [t really caug ht my intuj tion somehow a s beIn g a really si gni~jcant possiblity for his planners to

For about an hour and a half he and I talked in my office, wh e re [ intermixed a eneral descriptions and concepts with a demonstration o£ the NLS system .

We went slowly on the latt e r; he got some hands-on expe 'rience. 1 wanted especially :for him to reach a bas ic understandin p: ot the IIkno.ledge workshopll no"1ion, a nd to see for instance how the current system mana g ed to support colt&borative dialogue, what our use in suppurt o~ system development was like, what the documentation plans were (toward i'ull text/graphic capabi 11 ty), how the startin g stag e £or au g mentin g a given org anization would Likely beg in with the clerical-support sta~f and g et to the muna ge r's work in at a console much later.

Bialik (Jack Go~dberg joined us tater). The purpose here was to assess the possib Jlltes for SRI ' s being able to help him.

With respect to ARC, polntd out that t he chie~ recommendation ~rom me would be that he consider launching a long-term so1tware-engi neerln g wo rkshop u.ug mentatlon program: initially appo ,intlng his own man or @roup to become their Workshop Archl teet , buying NLS UtJ 11"ty support 1'or him to experiment with, and havin g him become a pa rtIci pant in our planned SEAS Community. Our hope was that the SEAS Community wouLd really support the applications architects in their long -term upgrading o~ techn~que and capabi~ity wi thin their home shops. This appeared to interest him, Rnd he said that he WQuld consider comin~ back to us about this within several weeks.

He broached another topic oL interest: marla geme nt information systems. Said that he was 1requently pressured toward providing service o~ thIs sort, and that he kept resisting it because he has seen so many dismu.l failures . He would like to lind some help in princ i ples and architecture here, so that he could in the 1uture conside r servinQ some o£ the needs. Jack Bial ik and Dave Brown picked up on thIs to pic , and there may be tollow throug h.

They oug ht to plan for one or more dispL a y consoles mostly dedicated to DNLS (or general-Workshop) use.

Propose to NASA that they connect their 1M LAC g uys, and work with Purdue via ARPANET, NLS-dialogue (INLAC djalo~ue??) ..

Ha.ve at least one grad student on the project 01 collaborating with the Workshop-development activity. Best payo~f in Item 1 above, a.t least inItiaLly. (Dick thoug ht that if this could come about soon enoug h, .Bob Belleville misht be Interested; see notes 1rom visit by Betlevitle and Dave Anderson last month --15120,3)

Cost: like $lSK/yr with overhead, expenses, etc .

(Assume that he is their "architect", and along with doin@ renl, colLaborative developments for aLL NLS-Workshop users to make use o~, he would assist training tocal people In using NLS ~or eXperimental applIcatIon, ~or collaborting with remote peop le, etc., ~ll of which would be heLp1ul in our general plan 01 deve~oping communitIes, and in g etting speciaL application areas involved, and in particular, toward the possibJle evolution of actlity in developin g Desi g er "'orkshop. )

JBN 6-APR-73 1 5 ~0 9 Need ~or Site Relations SpecialIst

In our Kro w~h from a small Nrc sta~f to a large r one, varIous tasks have been Ident Lf'led as speci"fLc enoug h and larg e enough to warrant a pe r son or part 01 a person being asslgned to handle each. Bven in doing this, I have the impression we have left a whole area of desirable actIvity untended. Partly because [ ~ea red that by historIcal accident or default the responsibilIty £or this area ~as mine, and partly because I was unable to present any clear soLution, J have been neg li g ent in defining this impression ~or whatever reso lution it can be g Iven.

At Mike's sugpestion, here is a discussion of the situation as I see it , althoua h not a :lu ll-blown position description.

We need a SITB IZ B,LATIONS SPECIALIST , or a NETWORK EXPEDJTOR.

When a Site Joins the Net_ork there are certain services we offer:

NIC diatrlbution

TN LS cou rs es

File space

Online JournaL capability

The Si~e has these services described and by dint o~ some efLort can g et the bene~it o~ t h ese. Bu t there Is no clear ef~or~ made to introduce Dew S ites to the com~unication £acilities available to them , and to hrin g them on methodically. In many cases J feel we are ne~lipent in p roviding assistance they could expect.

In the past ~he first problem lay in NIC's g etting notice of a Si te's existence . Then a call was made to learn the names o~ certain S ite personnel, and to estabLish NIC distrIbution. Throu g h NIC diAt ributlon -the Site learned 01' TNLS courses, a nd through heursay o£ their priv ileg e to access to r ile space a n d one or more directories. It has been notoriously hard to g et directories established for these, and the procedure 'recently establis hed is that WDK noti £ le9 Je11.

It has never been anyone's sole or even a prime responsibltlty to br ing a new Site on . We see what specIal attention has accomplished in brin@ing RADC and ARPA into knowledg e. Last weekend, JCN noticed that Na v al Shi p R 8 0 was hype ractiv e suddenly, and discovered what J knew, that they we re using TNLS to prepare an important report . Because he lelt like it, Jim g ave them a lot 01 extra hel.p. [0 contrast, J find, as was true this

mornin~ , that there Is usually no one a v ai l able to assist a Netwo r k use r wltb his d i ££iculties. One r esult of this Is that the user in trouble continues to assume that his trouhle is caused by us, by s om eth in g someone here d id to the system d urin g the nt Rht, for exampls . It bas bee n v e ry f r ustra.t i n g to me to g et call s on the N I C p hon e r egardi n g anything from TNL S to hardwaret and £ind no one who would take responsibil ity ~or talking to the person . rt is true that the p r obl e m may be ~ar f rom wha t the caller ascr i bes it tO t but an expedite r could trace the troub l e dow n.

It is also true that wIt h the workload t he Station Ag ent a nd her occasional assistan ts ca rry in pe r formin g the g e n eral dlstr .ibution, that sllecia l calls and ma illn ~s and ident i nputs are disruptive o£ good p r od ucti v i t y .

ALso it is t rue that ~l vJng res p onsib ility for network relation s is p r obably inappropriate 10r the S t at ion Ag ent , which is a position he l d by v ery capable and r espo n s i ble p eople , hut with u hig h rate of turnover, making contin ul -ty a nd con s istency unlikely. I t Is a ll we can do to b rln @ ourselve s back to baseline in that area, aft er e very chang e .

A Lso , the work as [ see i t f or information, which a re

includes some aspectSt such as calls likely t o be regarded us too menial

£or anyo n e with the back~round necessary to handle harder parts of the joh. And ye-t, I observe that JCN a n d DVM ha v e made such contacts with g aud ef~ect In their limited area .

1e need to Look at the situat ion, and fi n d out why , with an In.formation and Ag e n t Coo rdin ato r, a Sta tion Ag e n t , a Network Liaison, u. TNLS educatio n staff , and a Use r Interface , we are so o1ten ne~ tl ~e nt and unresponsive to ca ll s 10r help . An d whether there i s some way to assign a responsihili ty for coordinating all ~etwork Site relations so that some 01 us here , a nd many o £ ou r users don't see a voi d betwee n need and serv i ce .

The lin e pri nter wIll be u sed to outp ut tex1:, that Is, documents and repor t s at speeds g reater than 100 lines pe r mInute (LPM). T h e text will con tain alpha/ num e rics (upper and tower case cha ract e r s) a nd at le ast the usual set of symbo l s such as commas , parenthacies, quotation marks etc . The re ports I)roduced by the p ,rinter will. be used direc tly from the printer and/or cop I ed on u. Xerox copIer prior 10 use. The pape r to he used wIll be perphorated in 8 1' x 10 1/ 2" or 8 1/ 2 " x 11'1 sheets for conv i en t remo vu.l o~ the documen t sheets ~ ro m th e co ntinuous p rinter ou t put .

The p rint er wi ll be dr iv e n by an existin g hardware unI~ call ed the Te r minal I nte rfac e Processo r ( T IP) produced by Bo l~ Beranek Rnd Ne wman ( BBN ) o~ Cambridge , Mass . The T~ P Is par~ o~ the ARPA Network wh i ch interconnec ts over 20 v arying co~puti n g facIlities located about tbe na t ion. The TIP can be considered to consist o£ two components a Hon eywell 316 , which i s the data processor , and a BBN Multi Li n e Cont roll er (MLC ) which inter~aces u p to 63 te r minals to the 3 1 6 p r ocessor . Bo th components ar e housed in a s in ~ l e II Hlg h-Boy l' t ype cab in et . The p rinter will be connected to o n e of th e exlstin~ 63 terminal ports in the T I P , therefore, th e printer must con~orm to certa in e lect ric a l, hardware and log i cal por~ specI~lcations. The complete speci~icatlon I s co ntaine d in BBN Report No . 2184 enti le d " Te rmin a l Int erface Message Processor the BEN TIP Hardware Manualll.The essenti a l s of a po rt con nection a r e as £0110w9:

Each port will operate in a syn chronous or asynchronous fashlon.

Synchronous: a clock pulse is supplied to th e TIP by "the Terminal (external clock )

Data rtltes: input I; output- any rate up to 1 9 . 2 'Kbps .

As ynchronous: The TIP supplies its own lnternal clock after selection 01 the data rate.

Data rat esC bps ): input £; out p u t - 75, 110, 134 , 1 50 , 300 , 600 , 1 200 , 1 8 00, 2400 output only- 4800, 9600 , 1 9200

Inter"lace voltage levels con:form to E i A Speci:ficatlon Rs232 and the inlerface connector is the EfA S tandard data phone connector. (connector should be Cannon DA- 25P equi valent)

The ports are modem compatible, ho_ever, since the p rinter will be in proximity to th~ T IP the printer will b e di r ectly connected and no Dlodem will be require d . The Tl P requires the 'f o llowing connections when operating in the asynchronoUS mode!

W'HP 6-AP R-73 !IPS : whether, whither, wither?

~ PS: whether, whlther, wither?

It seemS to me that the NMUT's r esponse (l 5498 ,) to Pe t er ' s suggestion rega r di n g the us e of' ECL (1 5285 ,) is .right 1'0r the 1fIIrong reasons.

Peter's plan I s obviously the best one -- i f' we're wi~li ng t o t reat the reimplementation o~ NLS as a r esea rc h p roject to be carri ed out by 2 o r 3 peop~e and junked when/i~ co mp Let ed .

[ should add that. 1 thi nk such research mi g ht be q uit e valuable as a sou rc e 01' n ew approaches to aug mentation systems and shoul d be e nthus i as tically supported by ARC .

Ho we ver, the us e r e impLementati o n prob~ems:

o~ EeL is ~ess attractive i f' NLS is intendpd to address th e followin g

09 : 03

eng ine e r I'? lc4

These all appear to be difficuLt , l o n g term r esearch p r obLems -- and rel e van~ to the interests o~ ARC a n d at leas t some pe op l e at Xe rox a nd e l sewhe r e . To my knowled ge , the current EeL does not provide so lutions t o th e m, nor does it e~ai m t o be even tryin~ to. As Pete r says, Ee L is bein g developed by a bri g ht and energ etic g r oup , but they a re working toward their o .. n goa ls.

On th e other hund, MPS was o ri g in al ly conceive d ( by some of us at least) as u s te p towards addressing th e prob l ems mentioned above . J1: ther e is still interest in workin g on these prob~ems , then I think the con1: inued deve lo pme nt of NPS and its use in r ei.plementin g NLS is a g ood approach .

CPD B-APR- 7 3 16:30 On Command Recognition and Feedback

On Command Recognition and Feedback

The NLS command tan gu~ge employs an undellmited command Bt r~cture . Most commands may be specl~led by ty~lng only the ~ir91 character 01 the assoclu~ed command keyword , causing uncon~lrmed recognition of the commalld. rt i s P09sjb~e to ach ieve high command interaction rates usi g this app roach to command recog nition because the actual number o~ characters typed is minlmlzed . This approach works well as lon g as the command langua g e is small and static, but it poses di~tlcult j es for eXpan ding or chan g ing the lan g uaa e . New commands often are g Iven ad-hoc and sometimes undescrlptive names s o as to not conflict with exIsting co mma nds .

We need a beiter an more consistent approach to modeling c~mmand lan~uage recognIti o n and ~eedback.

C om ma nd Rec o g nition:

The command recognition process can be modelled by an ordered ~election of alternative command keywords. The process is hj erarchical in nature in that the set o :f keywords which are valid atternat~ves at any poInt in the command p ars In g Ls unique ly determined by the previously selected command keyworris.

Each command keyword may be recog ni zed b y i-ts minimum unJque s u bst rLn g ..

Co mmands keywords which have similar first letters or InItial substralngs are automatically permItted , but the keyword wIll not be reco g nized until the minimum unique SUbstring Is input

Com mand Feedback:

In thIs model command not single characters .

keywords are represented by strings and Thus the same string whi c h is used ~or

command recog nition may be lIsed to provide command :feedb a ck as
