Enjoined reading the statement. Re the "flatter" Internet in 5.1. since around 2000
seemingly there is a trend in changing upstream transit contracts to peering
arrangements. By Q1 2007 in the observed example over 80% of traffic is routed via
peers.

Statement 1. Would it be beneficial to define the targeted number of individual
prefixes in DFZ, specify the update rate and then architecture towards those
numbers? E.g. assume 1 AS per each 10,000 sq km of Earth's surface and 9 routes per
AS. It gives about 450K as the maximum number of DFZ entries providing an idea of
the router required processing power.

Statement 4. Make it more rigid "Allows end sites to switch providers without
configuration changes to internal end site devices".

Statement 5. seems redundant

Thanks,

Peter
