Who Benefits?
End Users - Latency, maybe
Content Providers- Server load, availability, disaster recovery, performance to end users, slow network buildout, “local” markets, PR value, etc.
Content Aggregators (Hosting Centers)- distribution of content, server load balance, new value-added services from content switching
Regional Traffic Aggregators (ISPs, Cable Head Ends) - links to backbone, end user performance
Global Traffic Aggregators (backbones)-system-wide benefits, scaling economies
Biggest Single Benefit is to Content Provider; but
Largest Total Benefit is to entity that aggregates both content and traffic, providing end-to-end service
