How do you count # of networks? 8M means - 8M of independent, multihomed companies. What is the reson to expect so many? Don't forget that today's number of networks is multiplied few times because you (foten) need to get more than 1 allocation. And what is a problem with 8M networks in next 8 years (if we easily handle 200K just now)? No, this model is well scalable and we better solve other, REAL problems, not mistical _# of networks_ one. ----- Original Message ----- From: "Per Heldal" <heldal@eml.cc> To: "Mikael Abrahamsson" <swmike@swm.pp.se> Cc: <nanog@merit.edu> Sent: Wednesday, February 15, 2006 11:45 AM Subject: Re: protocols that don't meet the need...

The current routing model doesn't scale. I don't want to sit 5 years
from
now needing a router that'll handle 8 million routes to get me through the next 5 years of route growth.
agree!
PI space for multihoming and AS number growth is a bad thing for scaling and economics, however you look at it.
agree!
Shim6 would hopefully curb the prefix growth very early in the growth curve as single entities won't need AS to multihome between two
different
ISPs.
agree!

All is well if shim6 succeeds it seems ... 5-10 years into the future. Do we all agree to postpone v6 till then?
If not there's a need for an intermediary solution. To me it seems like people want 2 things:
1. A working solution. The only alternative with current technology is PI end-site assignments.
2. Reasonable predictability. To make ever-lasting technologies and policies may be the dream in some research communities. The rest of us have to work with what we got and accept that we have to upgrade and make substatial changes to our networks from time to time. An alternative to satisfy those who fear the long term effect of a growing routing-table could be temporary end-site assignments from dedicated address-blocks. At some point in the future, when new-and-mature technology exist, the RIR-community could decide on new policies and decide to re-claim the entire block on e.g. a 24-month notice.
... just my $.02 compromise ;)
