Bits and Chaos


Between bits and chaos, a sysadmin stands.

Internet Traffic Consolidation

We had learnt and taught Internet as an hierarchy of ASN, starting from local ISP to regional to Tier 1, with traffic graciously moving between the levels.

This is no longer true, according to this presentation from NANOG47:

  • 150 ASN accounts for 50% of all Internet traffic;
  • Revenues from Internet Transit are declining, whilst revenues from Internet Advertisement compensates;
  • The new rule is 30/30: the 30 top destinations (Google, Yahoo, Facebook, …) accounts for 30% of all traffic, so if you are a provider you’d better make a deal with them: your customer would get a better Internet experience which is a commercial advantage: as a result, Youtube bandwidth bill is a lot less than you could imagine.

It’s time to rewrite some courses material.
