Is there a graphs shows how much prefixes in global route table are PA and how much - PI (maybe in percents)?
And also this one year-by-year (monthly?)?
Maybe there is no real "route table PI pollution" trouble in the real world?
Ok a bit late but maybe this is useful: - there is no easy way to distinguish between a PI and a PA prefix - increase in RIR delegations last year was about 6%, increase in advertised prefixes around 16% - there are less than 20000 AS numbers and some 180000 prefixes, so at least 160000 of these prefixes aren't the result of multihoming as such (although multihomers can also advertise more than one prefix for traffic engineering reasons or no reason at all of course) (If multihoming is going to be a problem then look at AS numbers, the ASes used by ISPs won't be significant in that case)
