based on ALL the ASN's of the people on the peering switch.. but in most cases anyone pushing any real traffic will probably not have fine grained samples enough to determine a peering relationship based on a single AS with this method. Maybe Im wrong but hey if you are taking 200megs from any one ASN I would hope you knew about it.Also, that method has the same "knowing the routes" problem as netflow. Whereever you are getting your list of ASN's route ASN.*"'s routes, there is pretty much no way they are accurate (for an ASN of ANY size).
The vast majority of the routes will be an intersection of routes announced by the AS to other AS (including looking glasses). Alex
