I don't think that anyone have ever filtered on old class-based sizes. What
I know is that the most restrictive filters have been on RIR allocations

Having recently read David Moore's paper on backscatter analysis,

an amount of traffic proportional to their size.

This is all great and wonderful, except for one thing - the RIR allocation
boundaries were never really meant to be used as official filtering prefix
length limits. I certainly support Verio's right to filter on whichever
boundaries make business sense to them. However, there is no denying that

Hello,
I am currently running a network of cisco 2621s with the OC-192 NM for my upstream

Seriously, I don't see OC768 coming online en masse until they get the
kinks worked out of optical switching. The transit times are so short thru
the innards, in the order of picoseconds, that electronics is way too slow
to perform such mundane tasks like determining where a packet is
