+
+   The letters below were discovered in September 1993 in a reverse
+   time-capsule apparently sent from 2023. The author of this paper
+   cannot vouch for the accuracy of the letter contents, but spectral
+   and radiation analysis are consistent with origin later than 2020. It
+   is not known what, if any, effect will arise if readers take actions
+   based on the future history contained in these documents.  I trust
+   you will be particularly careful with our collective futures!

+
+
+   Hi Jonathan!
+
+   I just wanted to let you know that I have settled in my new
+   offices at the Exobiology Lab at the Interplanetary Space
+   Exploration Agency's base here on Mars. The trip out was
+   uneventful and did let me get through an awful lot of
+   reading in preparation for my three year term here. There
+   is an excellent library of material here at the lab and
+   reasonable communications back home, thanks to the CommRing
+   satellites that were put up last year here. The transfer
+   rates are only a few terabits per second, but this is
+   usually adequate for the most part.
+
+   We've been doing some simulation work to test various
+   theories of bio-history on Mars and I have attached the
+   output of one of the more interesting runs. The results are

+   best viewed with a model VR-95HR/OS headset with the
+   peripheral glove adapter. I would recommend finding an
+   outdoor location if you activate the olfactory simulator
+   since some of the outputs are pretty rank! You'll notice
+   that atmospheric outgassing seriously interfered with any
+   potential complex life form development.
+
+   We tried a few runs to see what would happen if an
+   atmospheric confinement/replenishment system had been in
+   place, but the results are too speculative to be more than
+   entertaining at this point. There has been some serious
+   discussion of terra-forming options, but the economics are
+   still very unclear, as are the time-frames for realizing
+   any useful results.
+
+   I have also been trying out some new exercises to recover
+   from the effects of the long trip out. I've attached a
+   sample neuroscan clip which will give you some feeling for
+   the kinds of gymnastics that are possible in this gravity
+   field. My timing is still pretty lousy, but I hope it will
+   improve with practice.
+
+   I'd appreciate it very much if you could track down the
+   latest NanoConstructor ToolKit from MIT. I have need of
+   some lab gear which isn't available here and which would be
+   a lot easier to fabricate with the tool kit. The version I
+   have is NTK-R5 (2020) and I know there has been a lot added
+   since then.
+
+   Therese,
+
+   I wanted you to see the simulation runs, too. You may be
+   able to coax better results from the EXAFLOP array at CERN,
+   if you still have an account there. We're still limping
+   along with the 50 PFLOP system that Danny Hillis donated to
+   the agency a few years back.
+
+   The attached HD video clip shows the greenhouse efforts
+   here to grow grapes from the cuttings that were brought out
+   five years ago. We're still a long ways from '82
+   Beaucastel!
+
+   Gotta get ready for a sampling trip to Olympus Mons, so
+   will send this off for now.

+
+   David,
+
+   Many thanks for your note and all its news and interesting
+   data! Melanie and I are glad to know you are settled now
+   and back at work. We've been making heavy use of the new
+   darkside reflector telescope and, thanks to the new petabit
+   fiber links that were introduced last year, we have very
+   effective controls from Luna City. We've been able to run
+   some really interesting synthetic aperture observations by
+   linking the results from the darkside array and the Earth-
+   orbiting telescopes, giving us an effective diameter of
+   about 200,000 miles. I can hardly wait to see what we can
+   make of some of the most distant Quasars with this set-up.
+
+   We had quite a scare last month when Melanie complained of
+   a recurring vertigo. None of the usual treatments seemed to
+   help so a molecular-level brain bioscan was done. An
+   unexpectedly high level of localized neuro-transmitter
+   synthesis was discovered but has now been corrected by
+   auto-gene therapy.
+
+   As you requested, I have attached the latest
+   NanoConstructor ToolKit from MIT.  This version integrates
+   the Knowbot control subsystem which allows the NanoSystem
+   to be fully linked to the Internet for control, data
+   sharing and inter-system communication. By the way, the
+   Internet Society has negotiated a nice discount for nano-
+   fab services if you need something more elaborate than the
+   ISEA folks have available at XOB. I could put the
+   NanoSystem on the Solex Mars/Luna run and have it to you
+   pretty quickly.
+
+   Keep in touch!

+   Subject: Re: Hello from the Exobiology Lab!
+
+   Bon Jour, David!
+
+   I am writing to you from the Hyatt Geosync where your email
+   was forwarded to me from INRIA. Louis and I are here
+   vacationing for two weeks. I have some time available and
+   will set up a simulation run on my EXAFLOP account. They
+   have the VR-95HR/OS headsets here for entertainment
+   purposes, but they will work fine for examining the results
+   of the simulation.
+
+   I have been taking time to do some research on the
+   development of the Interplanetary Internet and have found
+   some rather interesting results. I guess this counts as a
+   kind of paleo-networking effort, since some of the early
+   days reach back to the 1960s. It's hard to believe that
+   anyone even knew what a computer network was back then!
+
+   Did you know that the original work on Internet was
+   intended for military network use? One would never guess it
+   from the current state of affairs, but a lot of the
+   original packet switching work on ARPANET was done under
+   the sponsorship of something called the Advanced Research
+   Projects Agency of the US Department of Defense back in
+   1968. During the 1970s, a number of packet networks were
+   built by ARPA and others (including work by the predecessor
+   to INRIA, IRIA, which developed a packet network called
+   CIGALE on which the CYCLADES network operating system was
+   built).  There was also work done by the French PTT on an
+   experimental system called RCP that later became a
+   commercial system called TRANSPAC. Some seminal work was
+   done in the mid-late 1960s in England at the National
+   Physical Laboratory on a single node switch that apparently
+   served as the first local area network! It's very hard to
+   believe that this all happened over 50 years ago.
+
+   A radio-based network was developed in the same 1960s/early
+   1970s time period called ALOHANET which featured use of a
+   randomly-shared radio channel. This idea was later realized
+   on a coaxial cable at XEROX PARC and called Ethernet. By
+   1978, the Internet research effort had produced 4 versions
+   of a set of protocols called "TCP/IP" (Transmission Control
+
+
+
+Cerf                                                            [Page 4]

+
+
+   Protocol/Internet Protocol"). These were used in
+   conjunction with devices called gateways, back then, but
+   which became known as "routers". The gateways connected
+   packet networks to each other.  The combination of gateways
+   and TCP/IP software was implemented on a lot of different
+   operating systems, especially something called UNIX. There
+   was enough confidence in the resulting implementations that
+   all the computers on the ARPANET and any networks linked to
+   the ARPANET by gateways were required to switch over to use
+   TCP/IP at the beginning of 1983. For many historians, 1983
+   marks the start of global Internet growth although it had
+   its origins in the research effort started at Stanford
+   University in 1973, ten years earlier.
+
+   I am going to read more about this and, if you are
+   interested, I can report on what happened after 1983.
+
+   I will leave any simulation results from the EXAFLOP runs
+   in the private access directory in the CERN TERAFLEX
+   archive.  It will be accessible using the JIT-ticket I have
+   attached, protected with your public key.

+
+   Hello everyone! I have been following the discussion with
+   great interest. I seem to remember that there was an effort
+   to connect what people thought were "super computers" back
+   in the mid-1980's and that had something to do with the way
+   in which the system evolved. Therese, did your research

+
+
+   Jon,
+
+   Yes, the US National Science Foundation (NSF) set up 5
+   super computer centers around the US and also provided some
+   seed funding for what they called "intermediate level"
+   packet networks which were, in turn, connected to a
+   national backbone network they called "NSFNET." The
+   intermediate level nets connected the user community
+   networks (mostly in research labs and universities at that
+   time) to the backbone to which the super computer sites
+   were linked. According to my notes, NSF planned to reduce
+   funding for the various networking activities over time on
+   the presumption that they could become self-sustaining.
+   Many of the intermediate level networks sought to create a
+   larger market by turning to industry, which NSF permitted.
+   There was a rapid growth in the equipment market during the
+   last half of the 1980s, for routers (the new name for
+   gateways), work stations, network servers, and local area
+   networks.  The penetration of the equipment market led to a
+   new market in commercial Internet services. Some of the
+   intermediate networks became commercial services, joining
+   others that were created to meet a growing demand for
+   Internet access.
+
+   By mid-1993, the system had grown to include over 15,000
+   networks, world-wide, and over 2 million computers. They
+   must have thought this was a pretty big system, back then.
+   Actually, it was, at the time, the largest collection of
+   networks and computers ever interconnected. Looking back
+   from our perspective, though, this sounds like a very
+   modest beginning, doesn't it? Nobody knew, at the time,
+   just how many users there were, but the system was doubling
+   annually and that attracted a lot of attention in many
+   different quarters.

+   that people and computers could carry out various kinds of
+   collaborative work if they had the right kinds of networks
+   to link their computer systems and the right kinds of
+   applications to deal with distributed applications. Of
+   course, we take that sort of thing for granted now, but it
+   was new and often complicated 30 years ago.
+
+   I am going to try to find out how they dealt with the

+
+   Therese,
+
+   I sent a few Knowbot programs out looking for Internet
+   background and found an interesting archive at the Postel
+   Historical Institute in Pacific Palisades, California.
+   These folks have an incredible collection of old documents,
+   some of them actually still on paper, dating as far back as
+   1962! This stuff gets addicting after a while.
+
+   Postel apparently edited a series of reports called
+   "Request for Comments" or "RFC" for short. These seem to be
+   one of the principal means by which the technology of the
+   Internet has been documented, and also, as nearly as I can
+   tell, a lot of its culture. The Institute also has a
+   phenomenal archive of electronic mail going back to about
+   1970 (do you believe it? Email from over 50 years ago!). I
+   don't have time to set up a really good automatic analysis
+   of the contents, but I did leave a couple of Knowbots
+   running to find things related to growth, scaling, and

+
+   increased capacity of the Internet.
+
+   It turns out that the technical committee called the
+   Internet Engineering Task Force was very pre-occupied in
+   the 1991-1994 period with the whole problem of
+   accommodating exponential growth in the size of the
+   Internet. They had a bunch of different options for re-
+   placing the then-existing IP layer with something that
+   could support a larger address space. There were a lot of
+   arguments about how soon they would run out of addresses
+   and a lot of uncertainty about how much functionality to
+   add on while solving the primary growth problem. Some folks
+   thought the scaling problem was so critical that it should
+   take priority while others thought there was still some
+   time and that new functionality would help motivate the
+   massive effort needed to replace the then-current version 4
+   IP.
+
+   As it happens, they were able to achieve multiple
+   objectives, as we now know. They found a way to increase
+   the space for identifying logical end-points in the system
+   as well increasing the address space needed to identify
+   physical end-points. That gave them a hook on which to base
+   the mobile, dynamic addressing capability that we now rely
+   on so heavily in the Internet. According to the notes I
+   have seen, they were also experimenting with new kinds of
+   applications that required different kinds of service than
+   the usual "best efforts" they were able to obtain from the
+   conventional router systems.
+
+   I found an absolutely hilarious "packet video clip" in one
+   of the archives. It's a black-and-white, 6 frame per second
+   shot of some guy taking off his coat, shirt and tie at one
+   of the engineering committee meetings. His T-shirt says "IP
+   on everything" which must have been some kind of slogan for
+   Internet expansion back then. Right at the end, some big
+   bearded guy comes up and stuffs some paper money in the
+   other guy's waistband. Apparently, there are quite a few
+   other archives of the early packet video squirreled away at
+   the PHI. I can't believe how primitive all this stuff
+   looks. I have attached a sample for you to enjoy. They
+   didn't have TDV back then, so you can't move the point of
+   view around the room or anything. You just have to watch
+   the figures move jerkily across the screen.
+
+   You can dig into this stuff if you send a Knowbot program
+   to concierge@phi.pacpal.ca.us. This Postel character must
+   have never thrown anything away!!

+
+
+   Jon,
+
+   thanks for the pointer. I pulled up a lot of very useful
+   material from PHI. You're right, they did manage to solve a
+   lot of problems at once with the new IP. Once they got the
+   bugs out of the prototype implementations, it spread very
+   quickly from the transit service companies outward towards
+   all the host computers in the system. I also discovered
+   that they were doing research on primitive gigabit-per-
+   second networks at that same general time. They had been
+   relying on unbelievably slow transmission systems around
+   100 megabits-per-second and below. Can you imagine how long
+   it would take to send a typical 3DV image at those glacial
+   speeds?
+
+   According to the notes I found, a lot of the wide-area
+   system was moved over to operate on top of something they
+   called Asynchronous Transfer Mode Cell Switching or ATM for
+   short. Towards the end of the decade, they managed to get
+   end to end transfer rates on the order of a gigabyte per
+   second which was fairly respectable, given the technology
+   they had at the time. Of course, the telecommunications
+   business had been turned totally upside down in the process
+   of getting to that point.
+
+   It used to be the case that broadcast and cable television,
+   telephone and publishing were different businesses. In some
+   countries, television and telephone were monopolies
+   operated by the government or operated in the private
+   sector with government regulation. That started changing
+   drastically as the 1990s unfolded, especially in the United
+   States where telephone companies bought cable companies,
+   publishers owned various communication companies and it got
+   to be very hard to figure out just what kind of company it

+   was that should or could be regulated. There grew up an
+   amazing number of competing ways to deliver information in
+   digital form. The same company might offer a variety of
+   information and communication services.
+
+   With regard to the Internet, it was possible to reach it
+   through mobile digital radio, satellite, conventional wire
+   line access (quaintly called "dial-up") using Integrated
+   Services Digital Networking, specially-designed modems,
+   special data services on television cable, and new fiber-
+   based services that eventually made it even into
+   residential settings. All the bulletin board systems got
+   connected to the Internet and surprised everyone, including
+   themselves, when the linkage created a new kind of
+   publishing environment in which authors took direct re-
+   sponsibility for making their work accessible.
+
+   Interestingly, this didn't do away either with the need for
+   traditional publishers, who filter and evaluate material
+   prior to publication, nor for a continuing interest in
+   paper and CD-ROM. As display technology got better and more
+   portable, though, paper became much more of a specialty
+   item. Most documents were published on-line or on high-
+   density digital storage media.  The basic publishing
+   process retained a heavy emphasis on editorial selection,
+   but the mechanics shifted largely in the direction of the
+   author - with help from experts in layout and
+   accessibility. Of course, it helped to have a universal
+   reference numbering plan which allowed authors to register
+   documents in permanent archives. References could be made
+   to these from any other on-line context and the documents
+   retrieved readily, possiblyat some cost for copying rights.
+
+   By the end of the decade, "multimedia" was no longer a
+   buzz-word but a normal way of preparing and presenting
+   information. One unexpected angle: multimedia had been
+   thought to be confined to presentation in visual and
+   audible forms for human consumption, but it turned out that
+   including computers as senders and recipients of these
+   messages allowed them to use the digital email medium as an
+   enabling technology for deferred, inter-computer
+   interaction.
+
+   Just based on what I have been reading, one of the toughest
+   technical problems was finding good standards to represent
+   all these different modalities. Copyright questions, which
+   had been thought to be what they called "show-stoppers,"
+   turned out to be susceptible to largely-established case

+   law. Abusing access to digital information was impeded in
+   large degree by wrapping publications in software shields,
+   but in the end, abuses were still possible and abusers were
+   prosecuted.
+
+   On the policy side, there was a strong need to apply
+   cryptography for authentication and for privacy. This was a
+   big struggle for many governments, including ours here in
+   France,  where there are very strong views and laws on this
+   subject, but ultimately, the need for commonality on a
+   global basis outweighed many of the considerations that
+   inhibited the use of this valuable technology.
+
+   Well, that takes us up to about 20 years ago, which still
+   seems a far cry from our current state of technology. With
+   over a billion computers in the system and most of the
+   populations of information-intensive countries fully
+   linked, some of the more technically-astute back at the
+   turn of the millennium may have had some inkling of what
+   was in store for the next two decades.

+
+   Therese and Jon,
+
+   This is really fascinating! I found some more material,
+   thanks to the Internet Society, which summarizes the
+   technical developments over the last 20 years. Apparently
+   one of the key events was the development of all-optical
+   transmission, switching and computing in a cost-effective
+   way.  For a long time, this technology involved rather
+   bulky equipment - some of the early 3DV clips from 2000-
+   2005 showed rooms full of gear required to steer beams
+   around. A very interesting combination of fiber optics and
+   three-dimensional electro-optical integrated circuits
+   collapsed a lot of this to sizes more like what we are
+   accustomed to today. Using pico- and femto- molecular
+   fabrication methods, it has been possible to build very
+   compact, extremely high speed computing and communication

+
+   I guess those guys at Xerox PARC who imagined that there
+   might be hundreds of millions of computers in the world,
+   hundreds or even thousands of them for each person, would
+   be pleased to see how clear their vision was. The only
+   really bad thing, as I see it, is that those guys who were
+   trying to figure out how to deal with Internet expansion
+   really blew it when they picked a measly 64 bit address
+   space. I hear we are running really tight again. I wonder
+   why they didn't have enough sense just to allocate at least
+   1024 bits to make sure we'd have enough room for the
+   obvious applications we can see we want, now?

+Final Comments
+
+   The letters end here, so we are left to speculate about many of the
+   loose ends not tied up in this informal exchange. Obviously, our
+   current struggles ultimately will be resolved and a very different,
+   information-intensive world will evolve from the present. There are a
+   great many policy, technical and economic questions that remain to be
+   answered to guide our progress towards the environment described in
+   part in these messages. It will be an interesting two or three
+   decades ahead!
