Do you also happen to have a breakdown of what ports this raffic was going to/from? The reason I ask iss that this seems to lead to a conclusion that a lot of the data was for "interactive" services such as telnet and the like as opposed to batch transfer type of connections such as ftp, and sendmail.

Scott -- i would agree if the proposed solutions were sane. The offered "vision" is pretty much the negation of what made Internet so successful. Sure, bring in suits and lawyers, institute centralized control, replace engineers who _do_ things with engineers whose only qualification is willingness to use the strangulation device. *That* sure will make Internet users happy as clams. Let's get real. --vadim

It is interesting how people perceive things differently. I didn't think Bob was harsh. Bob's opening sentence "The NANOG is our best bet for managing through the Internet's coming collapses" struck me as very positive. Some of his points were inadequately stated however. For example, the title "Techies, doers must join forces to help weave the Internet's new clothes" implies that the non-techies are the real "doers". If one reads between the lines, perhaps he is saying that there are still some Internet business model issues (MLPAs, settlement agreements, etc.) to address in the new Internet model. And clearly there are still some non-technical issues here. But he didn't come out and say that. As for his point about unpolished speakers, and the booting laptops comments etc. I think these are simply reflective of the working nature of the NANOG meeting. We are not formal here. We are not marketing here. We are judged on the technical content of the presentations. We are all in the same boat, working to identify and solve the most pressing technical problems. And we all have a stake in the stability and reliability of the Internet. Flashy presentations may impress the suits, but make the technical folks suspicious. Bryan Beecher once told me that the fancier the graphics, the grander the lies. (I guess that makes InterOp the site of the grandest lies then.) The point is, I think Bob was harping on something that is *not* a bad thing. BTW - I was assuming he was trying to be humorous with his 'bring on the executives and T-shirt' comment.

In an attempt to reduce the signal to noise ratio of NANOG, I felt like ATM should get equal time with registry policy for unending discussion of week award. In Bob Melcalfe's concept that all we care about is working code, I have included a PERL program for your benefit. The programs reads a histogram file like the ones kc generates from mae-west (http://www.nlanr.net/NA/Learn/packetsizes.html) and computes the overhead for various framing methods. Hopefully taking empirical data from the internet and giving people code will reduce the discussions of what the "cell tax" for real traffic is. Don't like my traffic, collect your own. Fighting over conclusions will be left to others. Jerry Here's the output from the 15 minute collection run on Feb 10th, '96: % packettax.pl < packetsizes.data total packets seen = 11708789, total payload bytes seen = 3010380871 HDLC framing bytes = 3080633605 HDLC efficiency = 97.72 ATM framing bytes = 3644304857 ATM efficiency = 82.61 ATM w/snap framing bytes = 3862101043 ATM w/snap efficiency = 77.95 and here's the crude but working code (copyright courtesy of the ISC) #! /usr/bin/perl # Copyright (c) 1996 by Internet Software Consortium. # # Permission to use, copy, modify, and distribute this software for any # purpose with or without fee is hereby granted, provided that the above # copyright notice and this permission notice appear in all copies. # # THE SOFTWARE IS PROVIDED "AS IS" AND INTERNET SOFTWARE CONSORTIUM DISCLAIMS # ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES # OF MERCHANTABILITY AND FITNESS.

Regarding our wonderful Mr. Metcalfe and his article at : http://www.infoworld.com/pageone/opinions/metcalfe/metcalfe.htm On again he has succeeded in generating a structured, well written article, that conjures up the image of a concerned parent shaking his head in dismay over a child that he had great expectations for. Of course, if had even the vaguest idea of what had been going on at NANOG he might feel a bit differently. It was funny, I'll admit, when we found that the projector didn't put out enough lumens to drive the LCD panel, and I know that I chuckled when I learned that there was no packet loss anywhere ;) But hey, if you spend 14 hours a day *every* day dealing with building even a minor backbone like mine, I feel that you kind of earn the right to chuckle. What Andrew, Curtis, Sean and the rest have earned, well, I don't want to inflate egos any more than they already are <grin>. Metcalfe feels that he was wrongly flamed for getting his facts wrong about who moderates NANOG. That isn't the case at all. He was flamed for being an ass and *printing* facts that were wrong. Oh he cited a URL that maybe contained bad info. And if we are not *real* engineers, well, how many *real* journalists don't verify their information with a couple of sources before they print it? Now don't get me wrong. Bob is a *real* engineer in my book. In fact, his article proves it. His petty attention to the bad points of NANOG and his omission of all of the good things that came out of it, well isn't that just what he accused *us* of? Oh sure Peter went off on a tangent during the DX.NET peering piece, but Peter *always* does this and we all would be worried if he didn't. What Mr. Metcalfe missed was the upwards of 50 (my estimate only) direct BGP peering sessions that were arranged at the CAIS party that evening and opened on various NAPs the next Monday. He also missed the fact the the RADB got updated and cleaned by an unprecedented number of ISPs (even if it is too much work for Sprint <grin>). In his years of "wearing a suit", I think Bob has forgotten that it is ultimately the results that count. We argue, whine, and moan, and it's amazing that the GW hall could hold all of the egos that were at NANOG, but after each event, how many bogus routes stop getting injected into the NAPs? How many fragmented announcements get aggregated more efficiently? Even the NIC listens and learns, Guardian is here (sort of). And Bob *has* an Internet to write on and about. Oh well. I spent quite a while designing interfaces that used a technology that Bob basically invented from scratch, and I actually *learned* about Ethernet before uttering my first complaint (well maybe not entirely true). Too bad he didn't pay NANOG (and the respective Internet backbones and NAPs) the same courtesy (I don't see him on the IAB). -vjb

In the spirit of the article someone should have T-shirts made up... A ties could be silk-screened on the front, and the back could have something catchy, like... "Save the Internet, wear a tie..." or "Bob said I could save the Internet, and as it turns out all I got was this stupid tie^H^H^H T-shirt" -Jeremy On Jun 18, 9:01pm, Paul Ferguson wrote: > Subject: Re: critique of NANOG meeting > All-in-all, an entertaining article. :-) > > - paul > > At 04:35 PM 6/18/96 -0700, Michael Dillon wrote: > > > > >I don't know if you folks are following Metcalfe's columns but this week > >the topic is NANOG and he mentions some names. > > > >http://www.infoworld.com/pageone/opinions/metcalfe/metcalfe.htm > > > > > >Michael Dillon ISP & Internet Consulting > >Memra Software Inc.
