There are 2 firms that evaluate the top global Internet backbones: Renesys and CAIDA. In this post CAIDA compares its data against DYN's data from 2014. (DYN owns Renessys). DYN puts out the Top 13 (Baker's Dozen) list of top global Internet backbones (by ASN) each year.

"AT&T (AS7018), now ranked #21, Qwest (AS209), now CenturyLink and ranked #14, and Savvis (AS3561), owned by CenturyLink since 2011, but with an AS that is still ranked #34."
