Re: Deprecating IPv6 (Re: draft-bourbaki-6man-classless-ipv6-00)

["Leddy, John" <[e-mail]>]

Innovation at the Network layer created the Internet.
Innovation at the Network layer has let it grow to the point it is at – including things we may not like, ex. NAT.
The Internet leveraged/adopted/re-architected innovation at the Network layer that occurred even outside of IP – all the other Networking protocols that existed – Appletalk, XNS/Banyan Vines, DECnet…

Without the innovation, we’d still be talking about SONET, X.25, ATM, FrameRelay – very narrow hourglasses/wineglasses.

How narrow of a waist spurs innovation at the layers above and below the Network layer?  
Should we regress in order to spur even more innovation?  
Perhaps IP itself limits innovation at the layers above and below IP?  Ex. Dual Stack – a difficult migration and operational state.

There are “no” Network protocols other than IP today – it is very hard to justify innovation outside of IP and IPV6 is the only platform where change is even possible and worth the effort.  It takes too long and migrations are expensive.

When there was a soup of networking protocols and no clear consensus about how Networking consolidates around a standard set of protocols for systems to communicate – “A core principle of the Internet architecture is to keep the waist of the hourglass/wineglass narrow” - because ubiquity was a major goal.  IP itself was the Major Innovation.

I don’t think there is a basis to say that that principle is correct in today’s Internet, my belief.

    I believe that innovation in the IP layer hinders innovation other places in the stack (aka the Internet).
    A core principle of the Internet architecture is to keep the waist of the hourglass/wineglass narrow to allow for Innovation above and below.
