Re: The future of NAPs & IXPs

[David Diaz <davediaz () netrail net>]

Hmmm more importantly routers that can do OC192, run your filters, queuing
and maintain line speed all at the same time.  Private peering sometimes
helps eliminate some of the filtering issues.  What about a dedicated
interconnect for VOIP?  Hard to try that over an interconnect, do TOS
routing/filtering or give a specific peer a pref over others.  It seems
that moving forward with everything over IP we're going to need a great
deal of features that dont exist now.

As for bandwidth, I think the prices will plummet too.  With certain
carriers making dark fibre available in quantity at ridiculusly low prices
wont will all have our own soon?

Doesnt everyone have a T1 to the home now?  gotta have one to pickup all
that spam...
