RE: [address-policy-wg] getting second IPv6 PA as a LIR
And why wouldn't the Internet work with 600,000 prefixes in the DFZ?
Now all of a sudden for instance Cisco 7600 3CXL isn't enough to old a full table (at around 750k).
Also, IPv6 uses twice the TCAM resources as IPv4...
so, basically what you are saying is that you know that your routers need an upgrade in 5 years and you don't want to pay for an upgrade or you can't figure out a business
which covers the costs for that? But you are telling small ISPs/NCOs/"hobbyusers"/whatever THEY don't get their business plan right if they don't can afford paying $$$ for PI space or rather would

to pay other bills with the money? WTF?!
------ No, the problem that the small ISPs you are speaking about will have to spend that money to swallow such routing table. And it is not $2000, "slightly" more...

do you have any numbers on that? because i don't see it. Even my old Pentium4 route servers do very nicely with that. And look at the processing power of the Route Engines of the hardware routers... wow are they slow! So, where does this come from? Will there be a break even point where current CPUs won't handle that anymore? My bigger problem with that actually is FORWARDING, not route calculation. The only reason i have hardware routers with ASICS is the wirespeed throughput, they still all have low-end CPU route engines for route calculation.... (But yes, slower CPUs == bringing up a BGP session takes 20min or so, we know that) And unfortunately i just now notices that this drifts a bit off topic. -- Mit freundlichen Grüßen / Kind Regards Sascha Lenz [SLZ-RIPE] Senior System- & Network Architect

Don't worry about computing power, small ISPs usually are less than 200Mbit/s total upstreams, to even if they handle 1G with today's CPUs it is not a big deal (rather stability can be a problem). More, probably within 1-2 years there will be a set of drivers/kernel support of handling packets by high efficients processors from... graphics ;) Regards, Marcin
