The 'serial-2' directory combines the 'serial-1' data with relationships
inferred from Ark traceroute data, and multi-lateral peering
https://catalog.caida.org/paper/2013_inferring_multilateral_peering.
To do this we first infer which AS owns each router independent of the
interface addresses observed at that router. The ownership inferences
are based on IP-to-AS mapping derived from public BGP data, list of
peering prefixes from PeeringDB, and the previously inferred business AS
relationships. Then we convert the observed IP path into an AS path
using the router ownership information (rather than mapping each
observed IP to AS directly) and retain the first AS link in the
resulting path for the AS graph.
The as-rel files contain p2p and p2c relationships. The format is:
<provider-as>|<customer-as>|-1
<peer-as>|<peer-as>|0|<source>
We disabled public access to 2020-02 and 2020-03 data since some of the links were not calculated correctly, therefore producing errors in customer cone and ranks
