The rv2atoms package contains perl scripts which analyze and process a Route Views table and compute BGP policy atoms.

Included in this Atoms download package is the straightenRV script, which reads Route Views tables (in either the text "show ip bgp" format, or binary MRT format) and outputs a variety of statistics and simplified information about the prefixes and ASes in said table. This can be used to map prefixes to origins ASes, for instance.

An alternative, optimized C implementation of the scripts are available.
