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. This paper describes the goals, architecture, and performance of a CDN brokerage system. Our system has been deployed on the Internet on a provisional basis. and our architectural ideas have helped advance the evolution of Internet standards for interoperating CDNs.
