Re: Multi-6 [WAS: OT - Vint Cerf joins Google]
1. Give us a maximum number of multihomers.
4 Million
So how do you know it's 4 million and not 4.1?
Could be 4.1 or even 4.2. I'm assuming those working on 4byte ASs know, if it's more we'll have to migrate again which would be silly so soon So about 4M it must be.
We know that 125k works today
That's quite a bit less than current SUP720-3BXL
(I'm being a bit conservative because in IPv6 the addresses are longer) so the storage requirements should sort themselves out according to Moore in 7 x 1.5 years, so that would work in 2013. Processing scales non-linearly, though.
If we need it then it will exist, if not then we won't be able to do that and will do something else instead just as V4 users are doing when they discover V6 doesn't do what they want (let's not rehash whether what they want is reasonable or sensible) brandon

And therein lies the problem.

I don't think the people working on 32-bit AS numbers are privvy to information that the rest of us isn't. But in any event, 32-bit AS numbers allow for 4 billion ASes, not 4 million.

I haven't seen the specs for that one, so I don't know if it can hold 500k _prefixes_ or 500k _paths_. Big difference. Also, not everyone is going to buy new hardware immediately.

That's not good engineering. It's a very bad idea to start a course of action without knowing whether you can finish it. Although we don't have as much time as we used to have, we still have SOME time to come up with new stuff that will make multihoming in IPv6 scale.
