Content Delivery, ip4r and mod_asn

[Dagobert Michelsen]

Hi folks,

Rafis ip4r extension for PostgreSQL works fine, I just tested the newly build mod_asn
which requires it. This is a step towards reworking our mirror infrastructure to include
real geo-based loadbalancing with 'mirrorbrain'. It works like this:
- fetch routeviews data containing the AS (autonomous systems) numbers from BGP and prefixes
- extract a mapping between ip network and AS number
- import this into a postgres database with ip4r (ipv4 range) datatype
- load module into apache which maps clients to AS number and adds that to the env and header
This can then further be used to select the closest mirror, a step that is not done yet.

If anybody is interested, I have my install notes (very brief) at
  http://wiki.opencsw.org/mod-asn
Unreleased packages are at
  http://buildfarm.opencsw.org/experimental.html#mirrorbrain
It also requires a apr-util dbd module with postgres enabled which also has been rebuilt at
  http://buildfarm.opencsw.org/experimental.html#apr-1.5


Best regards
