====== Autonomous System Map ======

I developped a tool for drawing relationship maps between Autonomous Systems in the Internet. Autonomous Systems can have three types of relationships as introduced by L. Gao:
  - customer-to-provider (c2p) (or if looked at from the opposite direction, provider-to-customer p2c),
  - peer-to-peer (p2p), and
  - sibling-to-sibling (s2s).

This tool uses data from the following sources :

  * [[http://as-rank.caida.org/?mode0=as-dump-info |AS information]]
  * [[http://as-rank.caida.org/?mode0=as-dump-peercones | Relationship data]]
  * [[http://as-rank.caida.org/?mode0=as-dump-peercones | AS name to number mapping]]

Feel free to download the scripts from my [[https://code.google.com/p/autonomous-system-relationship-map/ | google code]] or fork my [[https://github.com/samerlahoud/AS-Map-Scripts | git repository]].

An output example is given in the following figure. AS 2200 (RENATER) is a provider for FR-RENATER-IRISA and is a customer for LEVEL3 or GEANT.
