is CAIDA's ranking of
Autonomous Systems (AS) (which approximately map to Internet Service
Providers) and organizations (Orgs) (which are a collection of one or more ASes).
This ranking is derived from topological data collected by
CAIDA's Archipelago
Measurement Infrastructure and
Border Gateway
Protocol (BGP) routing data collected by the
Route Views Project
and RIPE NCC.
ASes and Orgs are ranked by their customer cone size, which is the number of their direct and indirect customers. Note: We do not have data to rank ASes (ISPs) by traffic, revenue, users, or any other non-topological metric.
