If you think we need more discussion around business cases and architectures when 20% of the world has actually done it already, then you are part of the problem. Maybe your business model or architecture is deficient, and that makes it uniquely difficult for you. Maybe Australians just don’t know how to run ISPs, and that’s why this country hasn’t quite nudged 8% adoption whilst North America, the ones who just five years ago were spraying threads all over NANOG about how hard and impossible it was, are over 30% adoption.</div><div class=""><br class=""></div><div class="">Get on with it.</div><div class=""><br class=""></div><div class=""><glares at TPG></div><div class=""><br class=""></div><div class=""> - mark</div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Mar 27, 2017, at 2:27 PM, Paul Wilkins <<a href="mailto:paulwilkins369@gmail.com" class="">paulwilkins369@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class=""><div class=""><div class=""><div class="">Mark,<br class=""></div>Thanks for posting this great summary of approaches to delivering ipV6 over UDP. It's important that we have active discussion, so the community both knows what approaches are being considered, and where the industry as a whole is moving. Because migration to ipv6 isn't purely a technical problem. There's the interplay of technology and business models that creates the ecosystem which can't exist without consensus solutions. And obviously starting a conversation is the first step to any consensus solution.<br class=""><br class=""></div>Where I think we need to be seeing more discussion, is around the business cases for the various architectures, scale, and opportunity costs. For instance, where is the road map once you have heavy use of ipv6 over UDP, and you discover lack of flow control is no longer specific to points of aggregation, but has become a feature of flows across the network?<br class=""><br class=""></div><div class="">Someone I think once thought, we'll just tack on 96(32 actually) extra bits and the address problem would be solved. The problem is the economies of scale for ipv4 are better than ipv6, and no one considered the operational costs of running both stacks, to allow the bridging needed as a fundamental part of a migration and successful evolution.<br class=""></div><div class=""><br class=""></div>Kind regards<br class=""><br class=""></div>Paul Wilkins<br class=""></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On 25 March 2017 at 15:10, Mark Smith <span dir="ltr" class=""><<a href="mailto:markzzzsmith@gmail.com" target="_blank" class="">markzzzsmith@gmail.com</a>></span> wrote:<br class=""><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><a href="https://blog.apnic.net/2017/03/24/udp-ipv4-stepping-stone-ipv6/" rel="noreferrer" target="_blank" class="">https://blog.apnic.net/2017/<wbr class="">03/24/udp-ipv4-stepping-stone-<wbr class="">ipv6/</a><br class="">
