CDN Brokering

Content distribution networks (CDNs) increase the capacity of individual Web sites and attempt to deliver content from caches that are located "closer" to end-users than the origin servers that provide the content. CDN brokering provides CDNs a way to interoperate by allowing one CDN to intelligently redirect clients dynamically to other CDNs.
