Distribution of this memo is unlimited.Introduction   The Computer Science Department of the University of California, Los   Angeles (UCLA) organized a Symposium on Very High Speed Information   Networks as the first in a projected series of meetings on Advanced   Computer Technologies, thus ACT ONE.  The time was chosen to also   commemorate the 20th anniversary of the installation of the first   Interface Message Processor (IMP) on the ARPANET which took place at   UCLA.   The Symposium took on a theatrical theme and a few of the speakers   could not resist the temptation to commit poetry.  This memo is an   attempt to capture the result.The Poems                                  WELCOME                                    by                             Leonard Kleinrock   We've gathered here for two days to examine and debate   And reflect on data networks and as well to celebrate.   To recognize the leaders and recount the path we took.   We'll begin with how it happened; for it's time to take a look.   Yes, the history is legend and the pioneers are here.   Listen to the story - it's our job to make it clear.   We'll tell you where we are now and where we'll likely go.   So welcome to ACT ONE, folks.  Sit back - enjoy the show!!Postel & Kleinrock & Cerf & Boehm                               [Page 1]

RFC 1121                  Act One - The Poems             September 1989                              ODE TO A QUEUE                                    by                             Leonard Kleinrock                   In the 20 years of funding                   Many fields has DARPA led.                   But the finest thing that they did bring                   Was the analytic thread.                   By that I mean they nurtured                   Quantitative research tools.                   And they always felt for all their gelt                   They got principles and rules.                   Indeed a wealth of knowledge                   Was uncovered and was new.                   And the common thread with which we led                   Was the analytic queue!                   Now a queue may have one server.                   If there's more, they form a team.                   Its dearest wish is just to fish                   In a quiet Poisson stream.                   If you want to model networks                   Or a complex data flow                   A queue's the key to help you see                   All the things you need to know.                   So the next time you feel lonely                   And wonder what to do,                   You'll soon feel fine if you join the line                   Of an analytic queue!                           THE PAST IS PROLOGUE                                    by                             Leonard Kleinrock                   The past is prologue so they say.                   So Scene 1 was played today.                   It set the stage to point the way                   To high speed nets on Friday.                   And old slow IMP, a costly link,                   Codes to fix the lines that stink,                   Ideas born in tanks that think,                   Tomorrow's distance sure to shrink.Postel & Kleinrock & Cerf & Boehm                               [Page 2]

RFC 1121                  Act One - The Poems             September 1989                   But first tonight we'll drink and eat.                   We'll take some time good friends to greet.                   Hear Bible class from Danny's seat.                   Those good old days were bittersweet!                               THE BIG BANG!                       (or the birth of the ARPANET)                                    by                             Leonard Kleinrock   It was back in '67 that the clan agreed to meet.   The gangsters and the planners were a breed damned hard to beat.   The goal we set was honest and the need was clear to all:   Connect those big old mainframes and the minis, lest they fall.   The spec was set quite rigid:  it must work without a hitch.   It should stand a single failure with an unattended switch.   Files at hefty throughput 'cross the ARPANET must zip.   Send the interactive traffic on a quarter second trip.   The spec went out to bidders and t'was BBN that won.   They worked on soft and hardware and they all got paid for fun.   We decided that the first node would be we who are your hosts   And so today you're gathered here while UCLA boasts.   I suspect you might be asking "What means FIRST node on the net?"   Well frankly, it meant trouble, 'specially since no specs were set.   For you see the interface between the nascent IMP and HOST   Was a confidential secret from us folks on the West coast.   BBN had promised that the IMP was running late.   We welcomed any slippage in the deadly scheduled date.   But one day after Labor Day, it was plopped down at our gate!   Those dirty rotten scoundrels sent the damned thing out air freight!   As I recall that Tuesday, it makes me want to cry.   Everybody's brother came to blame the other guy!   Folks were there from ARPA, GTE and Honeywell.   UCLA and ATT and all were scared as hell.   We cautiously connected and the bits began to flow.   The pieces really functioned - just why I still don't know.   Messages were moving pretty well by Wednesday morn.   All the rest is history - packet switching had been born!Postel & Kleinrock & Cerf & Boehm                               [Page 3]

RFC 1121                  Act One - The Poems             September 1989                         ROSENCRANTZ AND ETHERNET                                    by                                 Vint Cerf   All the world's a net!  And all the data in it merely packets   come to store-and-forward in the queues a while and then are   heard no more.  'Tis a network waiting to be switched!   To switch or not to switch?  That is the question.  Whether   'tis wiser in the net to suffer the store and forward of   stochastic networks or to raise up circuits against a sea   of packets and, by dedication, serve them.   To net, to switch.  To switch, perchance to slip!   Aye, there's the rub.  For in that choice of switch,   what loops may lurk, when we have shuffled through   this Banyan net?  Puzzles the will, initiates symposia,   stirs endless debate and gives rise to uncontrolled   flights of poetry beyond recompense!                                 UNTITLED                                    by                                Barry Boehm                   Paul Baran came out of the wood                   With a message first misunderstood                      But despite dangers lurking                      The IMP's were soon working                   And ARPA did see it was good.                   So in place of our early myopia                   We now have a net cornucopia                      With IMP's, TIP's, and LAN's                      Wideband VAN's, MAN's, and WAN's                   And prospects of World Net Utopia.                   But though we must wind up the clock                   With thoughts of downstream feature shock                      We all be can mollified                      For there's no one more qualified                   To discuss this than Leonard Kleinrock.Postel & Kleinrock & Cerf & Boehm                               [Page 4]

RFC 1121                  Act One - The Poems             September 1989Notes   The Symposium was held August 17 & 18, 1989, a Thursday and Friday.   "Welcome" was presented on Thursday morning during the Overture.   "Ode to a Queue" was presented in the Thursday morning session on   "Giant Steps Forward: Technology Payoffs".   "The Past is Prologue" was presented at the end of the Thursday   afternoon sessions.   "The Big Bang!" was presented during the after dinner events on   Thursday night.   "Rosencrantz and Ethernet" was presented at the morning session on   Friday on "Communication Technologies in the next Millenium" (note   that this version may differ slightly from the actual presentation   since it was reconstructed from human memory several weeks later).   The untitled poem by Barry Boehm was presented in the Friday   afternoon session on "Impact on Government, Commerce and Citizenry".   Barry gave his talk on "The Software Challenge to Our Technical   Aspirations" then introduced the next speaker with this poem.Security Considerations   None.Authors' Addresses   Jon Postel   USC/Information Sciences Institute   4676 Admiralty Way   Marina del Rey,  CA  90292-6695   Phone: 213-822-1511   EMail: Postel@ISI.EDUPostel & Kleinrock & Cerf & Boehm                               [Page 5]
