      In either case, Mark's point about scaling interconnect
bandwidth is a key question.  On one hand you have Tier-2 ISPs who
want fast ethernet based systems, because they don't really have an
immediate need to go for anything faster; on the other, you have   
backbone-to-backbone traffic that is rapidly moving to the point where
the only thing that will make sense is to trade a lambda.  It's hard  
to have public exchange that it is a good entry point for a Tier-2    
that also meets the needs of the backbones.  Using multiple different 
exchange methods to handle the different needs is one way around
the problem, but it comes at a cost in gear, support, and network
engineering.  The inertia in existing traffic exchange mechanisms
is also high enough that what tends to happen is that new connections
take new forms but the old mechanisms aren't taken out of service
at any speed--which again has a cost in gear, support, and network
engineering.

I don't believe its nearly this bad. It seems to me that the VAST majority
of backbone private peering is still happening at the OC3 level. In a
public exchange point where you're talking to multiple networks across a
shared media it makes sense to do GigE, multiple GigE, 10GigE, etc, with
OC48 or > feeding it, but due to the nature of the beast (the fact that
you're exchanging traffic in multiple locations with multiple networks),
private peering is in no such immediate danger.

Infact a lot of "backbone to backbone" peering is still done with DS3s
(think of the content providers with little need to talk amongst eachother
in bulk, GlobalCenter, Exodus, AboveNet, etc). The interesting traffic is
where the data providers (like those mentioned above) meet the data
suckers (@Home, AOL, etc), especially as streaming media takes off.

If we had a few more PAIX's and Equinix's in strategic locations the
internet would be a better place. :P
