Re: 20402 routing entries

If the return on routing entry (RORE) is large enough no one is going to 
particularly upset if mega-corp sends in a routing entry.  The place 
to get gain is at the tiny places (my home for example with a subnet with 
a tiny number of hosts).

We have a solution for that, we call it an InternetRelay, they are part
and parcel of what we are deploying on cable.  Surprise!


"Give me your network number, by such and such a date, or I turn you off"
 

As I suggested in my note this is too strict a position to take.  I
suspect that PSI like most providers work with their customers, and
could facilitate this kind of transition over time.  The issue is to
get from the current state to a better state.  I am not unwilling to
consider larger routers, hierarchy prudently applied, renumbering,
etc.  Why limit yourself when you have real problems to solve.
The implication that I am gratuitously suggesting  renumbering without 
solving a real problem is incorrect.  If everything was going just 
right, the topic would not come up.

And while your fording the stream with your tanks to
liberate those shackled by RevisionistDemocrats
you accidently crush
ten civilians and your 120mm gun goes off and you take out the town
Hospital.  "I'm sorry, I'm from the government, I'm here to help".  Basically
you can cause more problems than you are solving with your current tac.


If we figure out how to do this without any hierarchy as you seem to imply
would be desirable, then I hope the vendors build routers big enough to 
hold routes to all the telephone outlets in China.  We need some abstraction
and CIDR simply carries the IP subnetting model out to its logical 
conclusion.  The thought that we can eliminate all hierarchy is as silly
as demanding a strictly hierarchical system.

I'm not eliminating all hierarchy, I'm arguing (at least) mixed mode,
and of course no renumbering.


Let's not confuse CIDR with renumbering.  CIDR is to get reasonable
routing handles on "places" in the Internet.  In some cases this will 
be a 30 bit long prefix identifying a single host on a LAN and in some
cases it will be the prefix to all the IP systems in Mozambique.
Appropriate prefixes to meet routing requirements.  I think this fits your
notion of a non-deterministic path. 


If you think the current IP is going to deal with China then you have
lost sight of what are reasonable design goals.

Start again with new white paper.

Don't saddle the current IP with 
totalitarian-administered CIDR to reach that goal.
