ALL traffic passing between peered providers is BY DEFINITION sourced by a TRANSIT customer of one provider and sunk by a TRANSIT CUSTOMER of the other network. The correlary to this is that all traffic passing between peered providers was REQUESTED by one of the transit customers of one of those networks, who PAID for that transit to be provided to them!
There can be no 'request' without associated 'acceptance' of that requet. Therefore we have two 'half-links' where the content provider thinks it beneficial to pay for the other half-link in order to get its traffic delivered to the content consumer paying the other half. A corporate website covers its cost of the half-link in product sales while a more serious content provider sells subscriptions. A colo charges the website publisher not only for rack space etc. but also to provide the half-link to content consumer. So the colo has the fees and will pay if peering is asymmetric. -- tuomas.toivonen@fishpool.fi fishpool creations ltd http://www.kasvua.org/~toivotuo/ http://www.fishpool.fi/
