[AusNOG] Wrote an article for APNIC some here maybe interested in - "UDP over IPv4 – a stepping stone to IPv6?"

[Paul Wilkins]

Mark,
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.

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?

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.

Kind regards

Paul Wilkins
