AFTR the Fire: Carrier Networks and Incremental Deployment of IPv6

Google Tech Talk
January 21, 2010

ABSTRACT

Presented by Paul Selkirk, Senior Software Engineer, Internet Systems Consortium.

With the impending end of the unallocated pool of IPv4 addresses, the Internet faces a problem: there will be no more unused IPv4 space to assign as networks grow, only IPv6. Growth of the network in the future depends on effective deployment of IPv6.

But migration of the existing Internet-- end user systems, content sources, enterprise networks, carrier infrastructure-- to IPv6 is only happening slowly and irregularly. The technology originally intended to support incremental deployment of IPv6, "dual-stack," in which individual end systems are capable of using both IPv4 and IPv6, is not turning out to be practical on the universal scale it was designed for.

Several technologies are under development and early deployment to bridge the gap between the IPv4 internet and one that can interoperate between IPv4 and IPv6 in the interim-- perhaps lengthy-- before IPv6 is "mainstream" globally.

This talk will briefly lay out the operational constraints around IPv4/IPv6 co-existence, and then describe ISC's implementation of one particular protocol, DS-lite ("Dual-stack lite"). A new product, AFTR (for "Address Family Transition Router"), implements the DS-lite protocol and provides the core of a deployable architecture for IPv4/IPv6 co-existence in carrier networks.

uuhhmm , uhhhm a few words.. uhhmm ahhh... few more words.. uhhmmm. GEEZ that is annoying . Dude may be smart and all, but he cant speak for sh*t.

I can't listen to an hour of that to learn whatever this is all about. Too bad.

[prankmypants]

i love these google tech talks. always so informative!

[Solidacka]

Stop saying UMM

[momentousnation]

Great to see Burn Notice back. Just saw it online at lastnightstvshows (.) com

IPv6 could have been easily transitioned to SOLEY upon the fact that [most]end-users don't care one bit if its v4 or v6, as long as their connectivity works. ISP are apparently hardest hit YET they could have been giving out IPv6 addresses to their customers without the customer even knowing or caring and staying completely oblivious to the fact. Therefore the ISP's in my opinion are to blame for their lack or realizing that customers don't care which IP protocol they actually get.

speaker need more practice (I know, it is hard)

...but, why are there cut outs to Ella Fitzgerald?

[dumbkid0]

boy ... I concur, the speaker was talking too slow ...

[otur1]

I misspelled my previous rant.

I meant to say 'IT did not catch...'

Expensive because of installation of NEW (parallel) services in critical environments.

At home; Linux is free only if your time is worthless (BTW, I love Linux).

[otur1]

One of the reasons i did/do not catch on was IPv6 is too complicated (/expensive)  implement!

Love to hear from and about ISC, but that constant 'ahum, ahh, uhmm' from the speaker drove me NUTS!!!
