Carl Malamud: Internet talk radio, the medium is the message.
This is Geek of the Week and we’re here with Dan Lynch, who is president and founder of Interop company, and he’s also a long ‑time member of the Internet Architecture Board. Welcome to Geek of the Week, Dan.
Dan Lynch: Well, thanks very much Carl. Glad to be here.
Malamud: You’ve been a member of the IAB for a long time, and you’ve been officially the industry rep. How does your role differ from the other IAB members?
Lynch: Well, the industry rep’s kinda funny since I actually you know, have never really been a manufacturer of goods and services. But I…understand them more. I mean my background was I was basically a computer center manager for a lot of these computer science researchers that developed all of this technology. And so I got a chance to help make it work the first time. And the second time, and the third time. And understood the problems that the manufacturers, the regular vendors out there in the world were having in trying to you know, capture all of the knowledge and all of the methods of this internetworking technology.
So, I kind of went to the IAB people a number of years ago who were then simply all scientists, and said, “You know, you need to have somebody helping you understand what the real world’s trying to do with this stuff.”
And they said, “Oh, you’re the real world.”
I mean I was the real world to them, right. I mean, I was somebody who wasn’t a PhD in computer science but almost understood it. And I could explain it to others. So they…you know, just sort of…I was a surrogate for all those people out there in the real world. And also since I wasn’t really one of those bad vendors trying to make money, I could be honest, in their minds. I’m speaking a little bit out of school there, but I think you get the point.
Malamud: Has the IAB had to much of an academic focus? Obviously when they started it was a bunch of scientists, but has the organization changed over time so that it is taking account of the real world?
Lynch: Oh yeah. Very very much so. In the past what, four years, three or four years, the new people that have come into the IAB have been some of them from—you know, happen to be working for vendor companies like DEC [pronounced “deck”] and Data General and BBN. But they’re not there because they’re particularly associated with any particular manufacturer. It’s just they happen to be really good computer designers and network designers, who oh by the way now that it’s important in the world are working for real companies. I mean, this was all just a grand experiment fifteen or twenty years ago. And it got to be important, and when it’s important, some of the brain power obviously is out there delivering it to real live users.
Malamud: Is there still a focus on the Internet in general against commercial users? Do you still see that bias? Is it a research network still?
Lynch: It is absolutely not a research network. The fear— I mean…we’ve had the fear put into us. People are using it to make a living. And that’s wonderful. That’s called success, right. I mean you know, for most scientists, they want to design something, build something, that gets used. And the Internet gets used a whole lot. And so we’re all real happy that it’s being used, and very concerned that the architecture of it, the design of it, the underlying…you know, thoughts that guide it are adequate to fill the needs of how people want to use it.
Right now, you know, you’re doing this show over the Internet. We didn’t design it that way you know, twenty years ago. We designed a lot of flexibility in at the very beginning. But now it’s taken off very very fast. I mean, people are— MIME, you know, the multimedia mail stuff. Conferencing. This is tons of new activities going on on the Internet that are…you know, really outside of everyone’s control. I mean one of the beauty— I mean the Internet was designed to have no single point of control. We have succeeded. [laughs] There is no control of that beast.
Malamud: There is a group of people, though, a large group of people that attempts to put technology out—standards and protocols, and you know, MIME is one them. And that body was originally just the IAB, and then the IAB begat a group called the IETF—
Lynch: Right, when the work got hard… [both laugh] …we said you know, maybe we need more help. And now the IETF is now five or six hundred people, right. And the IAB is a dozen people or so. And then what happened what, two or three years ago we realized the IETF was so big that it needed its own operating infrastructure, which became what we call the IESG now the Internet Engineering Steering Group. And those people, the people who’re running that and doing that are really the ones closest to the problems anymore, right. And so the IAB’s role has changed from being one of being intimately involved in architectural design and detail, to being more of…are we going in the right direction? Are the right questions being asked? You know, and overview kind of activity as opposed to an operating activity.
Malamud: That evolution hasn’t always been very smooth. There was an incident after the IP version 7 decision or non-decision. And there was a lotta soul searching and there was almost a minor palace revolt. Do you think the current structure with an IESG making standards decisions and an IAB out there is gonna last? Are we gonna be able to move forward and continue deploying technology through these results on a periodic basis?
Lynch: Well… I mean. The easy answer’s I don’t know. If I could predict the future that well I could you know…be finding oil instead of sitting here. But it’s… I think we’re going to go through a few more steps. And the palace revolt that occurred last year…is no problem. It’s just, you know, more people anxious to get in there and row this boat. And a little disagreement about exactly how to do it, but there’s no disagreement about what we all want, which is to have this thing drive, right, and serve mankind. And how it gets done is you know, always a matter of judgment.
It’s kind of like… I hear these arguments and read these arguments on the mailing list that say oh, we’ve got to make sure we choose the right technology, the best technology, this should not be a political decision, blah blah blah and all those sorts of things. Well… I… That sounds wonderful. But it’s not being real.
What’s real is that the Internet has grown. It’s an obvious success. It’s a success primarily because of its original technology of letting people just stretch it any way they saw fit. So, essentially what was designed was a very flexible communications technology. And now it’s a success. And people are makin’ money. I mean, people are using it. So if the end users are successful in their lives by using the technology… And there’s billions of dollars a year worth of gear being sold to real companies, okay. And employing real people you know, designing, building, servicing, all of this technology; the internetworking technology both in the infrastructure stuff like routers and bridges and phone lines, and things like that. And also you know, all the applications in the end systems.
So, it’s too important to be left to scientists. It’s too important to be left to anybody to make all the decisions. I sort of believe what we have right now is there’s momentum. I mean, it’s moving. There’s a marketplace our there. If the IETF, IESG, IAB or whatever is the right place…if it does a good job of advancing the technology, of advancing designs so that more people can get more things done, then great. Then if the current place where all that work is being done, and there’s a little bit of heat and light about you know, who’s running it, how it’s being organized. But if that turns out to be too sludgy a process, or too much…you know, if it’s not making forward progress—that’s the simple measure—then something else is gonna happen, someone else—something else is going to happen in the real world. And you know, a committee will form itself of five or ten or twenty people who say you know, “A pox on all of you, we’re gonna go off and you know, here’s IP version 7.” Whatever it is. Whether it’s TUBA or SIP or IKE[?] or some combination of them or CLNP. I mean, they’re just gonna say that the market demands it. Customers demand it. Okay we’re running out of address space, we’re running out of manageability of the routing tables, and we’ve got to solve the problem. And you know, nobody’s come up with a straw man. And you know, the beauty is they don’t need anybody’s permission. There’s really no permission…the permission is the permission of the buyers. If the buyers are saying, “I like this, this does what I want. Here’s some money. I’ll take some and I’ll run it.” You know, the IAB doesn’t have any…holiness about it. Nor does ISO. I mean, you know, ISO is a UN treaty activity, okay. But it’s really just human beings saying, “Okay, you guys are going to run this for us, and we’ll take what you put out.” But if you don’t put out reasonable stuff no one uses. And so I’m not too worried about the politics of where the good ideas or the next ideas come from. I see the momentum of the marketplace using all this stuff is so big that there will be a solution.

[Incidental Tourist segment omitted]
Internet Talk Radio. Asynchronous times demand asynchronous radio.
You don’t think that momentum is gonna stop. The Internet is a global infrastructure and it’s going to be here for a long time?
Lynch: Oh yeah.
Malamud: It’s not just a stepping stone towards the real intelligent network?
Lynch: Uh…no you know, I— One of the beauties of the Internet is its simplicity. There’s a few simple rules that it has. I’m a member…or associated with, I’m a member of the board of the Santa Fe Institute, which is a nonprofit think tank kind of activity of multidisciplinary scientists. I mean, the people are scientists of either medical or mathematical or computer, economics and archaeologists. And they get together and basically teach each other their own methods of how they do research and how they explore in their own fields. And of course what they find out is that a method that works in one field is quite applicable to another field. Immunologists, real live immunologists describing how the autoimmune system works in a human being have been listened to by computer scientists who listen that and say, “Hey, that sounds like the right way to design and write virus protection software.” It’s funny the word “virus” we stole from them, okay, actually to describe bad programs or naughty programmers, is actually the source of the cure, right. I mean, go back to the same field and learn from them.
So anyway, that’s all a big segue that says that the simplicity of the Internet is its strength. And all it takes is a few simple rules. And the simple rules of the Internet are… Let there be no one in control. Let associations form, let people just connect to each other who wish to. Put the responsibility for the communication in the end systems. That’s really a corollary of let no one be in control. I mean because everyone if you wanna have some assurance that something happened, the insurance has to come from somewhere so it really has to be you know, in the end systems if it’s not in the network—you were talking about the intelligent network before. I mean that’s…you know, the phone company PPC right, okay, wanting to sells tons and tons of services when in fact they and no one can imagine and bring to bear all the services that people really can dream up by themselves. You’re really giving people a very fundamental new communication capability with the Internet technology. And it’s just foolhardy to think that someone who can design all that in advance and put it on a tariff sheet and forever more you’ll be eternally happy with those services and those services only.
So the Internet really is a groundswell kind of thing. I mean, you were INET with me Kobe, Japan last summer, okay, and saw and felt the emotion of those people from the emerging countries, right, who are just excited as can be about getting connected in a very intellectual and emotional way to the rest of the world, and such a rapid way of doing it. I mean, just by buying a few little modems and a PC or two or something like that and some little piece of software, they’re right into the mainstream late 20th century technology. And they have the brains to do it. And it’s not very costly to do it. And it’s just you know, that infection when you see newcomers come into it and you see how they react, boom, you know this is the right thing. It’s got a long play.
Malamud: You’re right, it is an amazing effect. In some ways the Internet is most useful the farther away from the core you get. If you’re at a national laboratory it’s nice. If you’re isolated someplace in the middle of the desert, it may be essential.
Lynch: Yeah.
Malamud: I’ve noticed that a lot of the TCP/IP-based computers that’re sold end up in some little LAN island. They’re not on the Internet. And I guess that raises a couple questions. One is, are these islands gonna connect up to the Internet. And also, are we meeting the needs of these people that are not connecting to the net. Is the TCP/IP standards process meeting the needs of a small corporate consumer?
Lynch: Well, the answer’s no, okay. And they’re isolated for two reasons. You know, number one it’s easier to stay isolated because they don’t have to worry— They hear well, I’m not a government thing or whatever, I don’t ha— The acceptable use policy. I don’t know if I should be on the net or something like that. And so they just stay off. Why bother.
But, if they wanted to get on, and they almost all can—I mean I sort of believe that this whole AUP thing is silly. I mean…you know. But if they want to get on, how do they find anything? And that’s the hard part, right? You know, you have this…the White ages, I mean. We’ve had these various X.500 experiments and DNS things and… You know, I forget what the exact technology is, okay. The idea of having this giant White Pages in the sky you know, where everything is connected to everything and you can learn anything about anybody you want to and all that sort of jazz…it…it just…it doesn’t work. It doesn’t make sense from an economic standpoint…you know, from a social standpoint, from a legal standpoint. So, we have this problem of when you get on the Internet you know, well what do ya get on to? Because there’s nobody in charge. There’s just people out there communicating who want to communicate and who form subgroups, or collections of people, and they pass each others’ addresses around in names of files, and you know… It’s seductive to think oh well that could all just be in one giant file, you know what I mean? One giant database in the sky. It’s all just data, right. And it’s all pretty—you know, there’s probably only a thousand different kinds of entries. Maybe it’s 200, maybe it’s 10,000—you know. But I mean there’s some finite number of attributes that you might look up things by. We’ll all need— You know, Steve Chen will never go out of business, okay. We’ll all need Super Crays just to do a lookup of a name.
So you know, think about the voice telephone system which is rather pervasive worldwide. There’s no single White Pages, right? I you wanna get someone’s name in Lyon, France…I mean, you know, you go to the expense of calling up the operator in Lyon, okay. A special kind of directory assistance thing, you know, fishing around, right. And if you don’t speak French well then you gotta find a translator, I mean you know, whatever, in order to get someone’s phone number. So, that’s just not all done automagically in the sky. And there’s just lots of good social reasons and business reasons for that.
Malamud: So how are we gonna get these people on the net, then? I’m assuming that’s a good thing to do, right, to connect these little islands up so we can talk to ’em if we want to. Not saying we have to talk to ’em.
Lynch: Yeah.
Malamud: What’s it gonna take to get—
Lynch: Well I think the first thing you got to get ’em on is just email. Okay that’s the first part, right. That’s the benefit, Okay. And of course we all know that email is a…you know, you don’t have to be completely and fully connected in order to have email connectivity. It might take a few hours of polling and dialing and things like that as a sort of store-and-forward system. And it’s not a full live IP-connected way.
And so the first way is to get them hooked on email. And that problem’s basically solved. What I mean by that is you can buy from…you can have your little local mail system. And whether it’s a SMTP email system, or a Novell mail system, or Microsoft or whatever that does all your local isolated mail. And then buy an account at MCI, or buy an account at Spring, or buy an account at AT&T. Or CompuServe or you know, any of these services. And then you can plug all your mail through that and use those as forwarding agents. That’s what I see happening, okay, is those commercial mail services are really becoming the backbone and mail forwarders. They’re becoming mail forwarders and not so much that people actually use them to do the mail on.
For instance I know a company that started out an MCI Mail, and they had like a couple thousand people using MCI Mail. And then they then they bought Lotus Notes, okay, which gave them a richer way of manipulating their information. And they use Lotus Notes now as their mail system, but they still use MCI to actually deliver the bits. But they no longer use the MCI front-end or anything like.
Malamud: So MCI in that case is turned into a transit net.
Lynch: It’s turned into a transit net, okay—
Malamud: They’re a part of the Internet backbone.
Lynch: They’re a part of the Internet backbone as far as I’m concerned, absolutely right you know. I mean, I get mail from my headquarter’s company through MCI. And they have NetWare— I mean it’s just this giant hodge podge…and it just kinda works. And so that gets people infected, gets them going of, you know— And you can sign up for MCI Mail in you know, Ethiopia. It doesn’t matter. They’ll give you a number to call. I’m not sure it’s absolutely 100% universal, but I’ll bet it’s very close.
And then you get hooked. And then you say okay, well now I want some real real-time connectivity. So I can send files around of arbitrary size and all that sorta jazz, and listen to Internet Talk Radio. Whatever it is you want. Then you’re motivated to go the next step, okay, which is to go buy a router from somebody, or lease a router or lease a service. I mean it’s kinda too bad— You know, I come from a technical world and I always think in terms— And I was a computer guy, you know, so I always think in terms of getting hardware, right, buying the software, configuring it, and running it and all that jazz, you know. Most people really don’t want to bother with that. They want to buy a service, right. I mean they just wanna call a phone number up and say, “Here’s what I want, and where do I bring something over and plug it in. And send me the bill. And I’ll argue about the bill, but I just wanna see a bill and some service.”
And that’s the next step. That’s the next commercial step for the Internet, is to have service providers who just do that and do it for a reasonable price, but take the headache of operating your network away from you. It is a headache.

It sounds like you don’t particularly care if it’s NetWare on this island and if it’s TCP/IP on that. It’s just—it’s a hodge podge that works.
Lynch: It’s a hodge podge that works. I mean, I used to have this grand hope that it was all gonna be one thing, you know? And at first I thought it was going to be XNS. The stuff that came out of Xerox—
Malamud: You’re showing your age.
Lynch: Yeah. Cuz I saw that stuff well, back at Xerox PARC when it was called PUP, PARC Universal Protocol back in the mid-70s. And it was pretty neat. And they were actually doing something with networking besides just sending files around. Which I call sending completed units or work. That’s what a file is. That’s dead data, right. Okay, and someone else wants to look at the dead data. That’s fine, there’s a lot of value in that. But you know, what about doing things because there’s a network in place, that you couldn’t do without a network like you know, combine calendars as a simple example, okay, or big sales meetings or any kinda organizational meeting in real time in many disparate locations.
But… The Inter— See, where was I. I lost my train of thought.
Malamud: Question being um…if there’s a hodge podge out there does it really matter if we’re using TCP/IP or…
Lynch: Okay. Yeah. So I thought there was going to be you know, one— First it was gonna be XNS, okay. Then Xerox didn’t let go of everything and so that wasn’t going to be it. And then it looked like well, maybe it’s going to be TCP. And I saw TCP really take off in the mid-80s, and it was solving a lot of problems. It was a bit barebones. And then ISO stepped up to the bar and said, “Oh no, TCP is just the training wheels, okay. ISO, the real thing.” And I look at all the ISO definitions and said gee whiz, yeah that is sorta TCP on steroids, right. It’s got almost everything you want, plus things—
Malamud: Plus more.
Lynch: Plus more, that you may or may not want, okay. But you know—
Malamud: Feature-rich.
Lynch: It’s feature-rich, okay. And so I thought well that’s going to be the great hope, okay, and the great savior for all of us. And I watched it try, and essentially stumble in a lot of places, and have some success but you know, not take over the universe. And then alongside in the PC world is NetWare, okay, which I sorta laughed and said heh, that’s just a little printing protocol, or a file-sharing protocol and a printing protocol. And well, son of a gun, 20 or 30 million computers later, it’s sort of big, and important, and does a lot of great work.
And so I sorta realized there’s not gonna be one winner. There even can’t be. And the reason there can’t be is the technology keeps moving ahead so fast that no one center of excellence can encompass it all. And you know, we’ve got this whole new thing taking off with mobile computing, right, and mobile data. And the people who are sweating out NetWare, or sweating out TCP, or whatever it is just…are also paying strong attention to mobile data needs. And so the people who are paying strong attention to that are developing their own slightly different protocols, and slightly different methods for communicating. And when that stuff becomes useful, it’ll get incorporated. There’ll be yet another kludge box—hardware, software, whatever—that you can buy for somebody to hook together some magic cap stuff, and some MIME stuff, and some UUNET, and on and on and on. So it’s just going to be this giant hodge podge in the sky. Perhaps forever.
Malamud: And that’s a very different dream from what for example the OSI community had originally intended [crosstalk] which would be a single universal ultimate protocol.
Lynch: Yeah. Yeah. I don’t see it… I don’t see it happening. I don’t see the technical force for that happening. I don’t see the market force. I think if you get the thing down to half a dozen reasonable competitors at any one point in time, that’s enough. N squared where n is six is only thirty-six, you know. And that’s not too bad a price to pay for diversity. See, for having diversity. The other side of that is, you get diversity. And we know from our knowledge of the world and the universe that diversity is a good thing. You get new ideas.
Malamud: Mutations are good.
Lynch: Mutations are good, you know. And some are bad. And the bad ones don’t get used, or don’t propagate for whatever reason and go away, and the good ones get you know, jumped on.
Malamud: As a member of the IAB, I’ve noticed that members of the Internet Architecture Board seem to have an appreciation for fine wines. Was at one of the selection criteria for IAB members?
Lynch: Well, no no no no no no. I’ve always been interested—well not always. I mean, not as a callow youth. But when I moved to Northern California in the early 70s, I happened to fall into a group of people at SRI who were the founders and owners of a little boutique winery called Ridge Wines, and they made really good wines. And they used to have them at the parties on Friday after work and things like that, and at their homes. I went gee, I’d been used to drinking you know, Gallo Hearty Burgundy, right, which I thought was okay. Until I got introduced to some really good wines. And so no, I’ve always ever since then been a wine collector, connoisseur, calling it what you like.
Malamud: You’ve got a bit of a collection?
Lynch: Oh sure. Oh sure, Carl, you know. You’ve been there.
Malamud: [laughs] I’ve appreciated it. Definitely fine wines.
Lynch: It’s wonderful. It’s like networking. It something you can share with friends.
Malamud: Well this has been Geek of the Week, and we’ve been talking to Dan Lynch. Thanks a lot Dan.
Lynch: Good night, Carl.
