Hi Virgil, It appears that vizAS detects connections between ASes when they are observed as adjacent on paths reported by Route Views [0]. When I construct AS-level routing maps (e.g. as in [1]), I combine Route Views data with the AS-level topology produced by CAIDA [2]. The CAIDA topology is created from links observed in the traceroutes continually performed by their three (I think) teams of ~12 probers each.
Do you know how APNIC/RIPE produces the “high-quality BGP-peering graphs for the entire Internet”? I know that RIPE has been building a pretty large Internet measurement platform called Atlas [3]. I wonder if they are using some of that data.
