I don't believe that any of the forces you mentioned have ever
made a fundamental change to the way we do routing.  Sure, they
have made changes to the internal function of routers, but, the
switch from BGP3 to BGP4 (which was the last significant change
in routing structure) was done by IETF.

What is needed now is a fundamental change in the routing
architecture and protocol.  BGP4 will not scale.  We have
to come up with a way to separate the interdomain
topological locator from the End System Identifier.  We need
to have some mechanism for aggregating paths to said
topological locators.  Finally, we need some  mechanism for
quickly and securely mapping End System Identifiers to
topological locators at the edge of the default-free zone.

Such a change is not likely to come from operators, vendors
or end users.

So you're saying that IETF isn't responsible for IPv6?  Other than
things which can be implemented on a site-by-site basis without requiring
a change in the protocol, I don't believe there have been any
operational improvements in the internet outside of the IETF

The model of open public discussion can scale well if there is
appropriate representation of the stakeholders and good moderation
and facilitation of the discussion.  However, over time, almost
every group loses or fails to achieve at least one of these two
properties.  I am not opposed to the model... Indeed, I think it
is the best model.  However, it does have flaws and an awareness
of those flaws is important.


If it wasn't crypto-signed, it probably didn't come from me.
