This 1986 film on packet switching was originally a videodisc presentation for an interactive display at AT&T's InfoQuest Center in New York City. The incomparable Bob Lucky, Director of Research Communications and Science at Bell Labs and Carl Sagan doppelganger, hosts the video and delivers the details of the technology in a manner that is both palatable and understandable. He's joined by a slew of Bell Labs engineers who worked on or with the technologies involved: Gottfried Luderer, Dave Berglund, Joan Bachenko, Ted Wright, Larry Rabiner, Dick Muise, Eric Petajan and Bruce Ballard.
The topics covered break down into two main parts:
Packet Technologies
* advanced packet technology
* how packet switches worked (with animation)
* how speech, image and data is packetized
* multimedia conversation as the wave of the future
* how to process the avalanche of information
* the packet phone
* the future of conferencing
* wideband packet technology
* self-routing packet switching
Speech Recognition/Voice Recognition
* computers and syntax trees
* individual word variability and how to process
* capturing visuals, i.e. videotaping lip parameters used in order to improve processing

It's interesting that this level of technical detail was made available to the general public. Much better than the "dumbed down" approach we take today.

Bell Labs is still around. Just owned by Nokia now. On a somewhat unrelated note; I kind of wish AT&T, Verizon, Sprint, T-Mobile, Nokia, Comcast, Charter and CenturyLink were to merge and reform the Bell System. The scale would allow for potentially lower prices, regulated of course, as monopolies should be. It would also allow for better service, as universal fiber to the home would now be standard for everyone even in rural areas.

This video shows that the AT&T already had Gbit capabilities back in the 80's. They speak in terms we still use today. As I always say, there's hardly anything that we have nowadays that wasn't already thought of or done in the 80's. See computer learning at 10:10 on the screens behind the speaker.

This was pretty much state of the art up until DSL became mainstream around 2000 or so, but with GUIs and browsers. Those guys basically already had access to VCS systems (or at least could share diffs over the net). Today we have all sorts of tools nobody knows how to use properly. Similar stuff with speech synth, pretty good for the day- I mean 1986!!!- and it's still pretty crappy today. Some things don't seem to evolve, instead everybody's just watching crap videos on Facebook and stuff.

@James_Knott Год назад

Years ago, I worked for the company that provided the Telnet X.25 network in Canada. This was years before the Internet became popular. Also, back then, ISDN was supposed to take over things like phones and FAX, as well as other data. For some reason, it didn't take off in North America, so while primary rate ISDN was used a lot, basic rate was rare. It was about 20 years after this video that I first saw voice over IP.

Pre cursor to ISDN-BRI but it was almost obsolete as soon as it was introduced in 1988. It was quickly phased out by emerging DSL technology. ISDN-PRI technology is still used but is being phased out in favor of lower cost SIP-VOIP technology; or in layman's terms voice over the internet.

@oprahwinfrey878 8 лет назад

These systems communication rate fluctuated at roughly 4 - 300 (and maybe 800) BAUD. To give you an idea of how painstakingly slow these modems were, A modern day dial-up modem -- connected to POTS -- can generate speeds up to 56,000 BAUD (56K). And we all know go delayed these speeds were/are. If you want to relive this utterly mind blowing connection speed, you could pick up a 300 BAUD modem on eBay or you purchase a satellite phone connected to Iridiums network. This satellite network -- which took off in 1997 -- supported data speeds up to 2.4 Kbps (2,400 BAUD) and is still currently used to this very day.

@MaximRecoil 5 лет назад

"A modern day dial-up modem -- connected to POTS -- can generate speeds up to 56,000 BAUD (56K)" No. A 56 kbps modem is typically 8,000 baud. It sends 7 bits per signal transition, which equals 56,000 bits per second.

10:10 Speaking of speech recognition, in the early 2000's when I typed with two fingers, I picked up IBM Via Voice software complete with headset to write a long term paper. Worked great! Basically read the text book in my own words, lol. Back then professors were threatening to enter term papers into a program to detect plagiarism. I don't think that ever happened. Not that I cut and pasted anything.

@Minalkra Год назад

Sooo ... how much of this actually made it out of the lab? Concurrent question, how much of this formed some sort of basis for modern technology? Lastly, if any of this formed the beginnings of modern packet transmission, how much of it was utilized in the standards that were adopted later (or the descendant technology perhaps is a better question)?

i laughted so hard hen the computer spoke and she said "that is state of the art speach synthesis" xD Also thought i recognize all that hardware from DEC - it was partly buying such things at thrift stores in the 90s that led to me to become a self taught embedded systems engineer creating demos and reference and research systems - a field i've been absent from but hope to return to soon ... i miss having white boards full of concepts and ideas and working with emerging technologies which later become commonplace.. it is a really satisfying feeling and experience i am greatful to have and hopefully soon will have again...

Prior comments on this video seem to completely miss the point that they are talking about is now called "IP" technology, which is the backbone of the Internet and ALL communications today! THIS WAS REALLY ADVANCED STUFF IN 1986!! Very forward-thinking but, like all other U.S. companies in the era, it was initially ignored as a technical novelty.

@Frisenette 8 лет назад

No it was not very advanced. Packet networks had been thought up and done for some twenty years at the time.

@thejoelpatrol 5 лет назад

Not really. Bell Labs was doing research on TCP/IP in the 80s, like a lot of people, and maybe the switching fabric they designed could be repurposed for that, but that is not what they're describing here. When SIP/RTP and other VOIP technology was developed in the 90s, it wasn't immediately obvious that it would take over. IP wasn't originally envisioned to be good for that.
