Alexi, Ah, You mean the excellent 'The Mythical Man-Month' Fred Brooks wrote a second edition a few years back. I had not thought of IPv6 in terms of the second system effect but you are absolutely correct in your appraisal. Scott C. McGrath On Wed, 6 Jul 2005, Alexei Roudnev wrote:
IPv6 is an excellent example of _second system_ (do you remember book, written by Brooks many years ago?) Happu engineers put all their crazy ideas together into the second version of first 9succesfull) thing, and they wonder why it do not work properly. OS/360 is one example, IPv6 will be another.
IPv6 address allocation schema is terrible (who decided to use SP dependent spaces?), security is terrible (who designed IPSec protocol?) and so so on.
Unfortunately, it can fail only if something else will be created, which do not looks so. ----- Original Message ----- From: "Daniel Golding" <dgolding@burtongroup.com> To: "Scott McGrath" <mcgrath@fas.harvard.edu>; "David Conrad" <david.conrad@nominum.com> Cc: <nanog@merit.edu> Sent: Wednesday, July 06, 2005 8:58 AM Subject: Re: OMB: IPv6 by June 2008
There is an element of fear-mongering in this discussion - that's why many of us react poorly to the idea of IPv6. How so?
- We are running out of IPv4 space! - We are falling behind <#insert scary group to reinforce fear of Other>! - We are not on the technical cutting edge!
Fear is a convenient motivator when facts are lacking. I've read the above three reasons, all of which are provable incorrect or simple fear
mongering,
repeatedly. The assertions that we are falling behind the Chinese or Japanese are weak echoes of past fears.
The market is our friend. Attempts to claim that technology trumps the market end badly - anyone remember 2001? The market sees little value in v6 right now. The market likes NAT and multihoming, even if many of us don't.
Attempts to regulate IPv6 into use are as foolish as the use of fear-based marketing. The gain is simply not worth the investment required.

You do make some good points as IPv6 does not address routing

or multi-homing which would indeed make a contribution to lower OPEX and be easier to 'sell' to the financial people.
As I read the spec it makes multi-homing more difficult since you are expected to receive space only from your SP there will be no 'portable assignments' as we know them today. If my reading of the spec is incorrect someone please point me in the right direction.
IPv6's hex based nature is really a joy to work with IPv6 definitely fails the human factors part of the equation.

IPv6 would have been adopted much sooner if the protocol had been written as an extension of IPv4 and in this case it could have slid in under the accounting departments radar since new equipment and applications would not be needed.
IPv6 would have been adopted much sooner if it had solved a problem that caused significant numbers of end users or large scale ISPs real pain. If IPv6 had actually addressed one or more of routing scalability, multi-homing, or transparent renumbering all the hand wringing about how the Asians and Europeans are going to overtake the US would not occur. Instead, IPv6 dealt with a problem that, for the most part, does not immediately affect the US market but which (arguably) does affect the other regions. I guess you can, if you like, blame it on the accountants...
