"Internetworking of Content Delivery Networks" sets out to establish the basis for developing advanced content management and delivery solutions that are scalable, high performance, and cost-effective. It introduces techniques to enable coordination and cooperation between multiple content delivery services, which is termed as “CDN peering”. This book addresses five key issues ? when to peer (triggering circumstances), how to peer (interaction strategies), whom to peer with(resource discovery), how to manage and enforce operational policies (request-redirection and load sharing), and how to demonstrate peering applicability (measurement study and proof-of-concept implementation). It describes utility-based techniques for resource discovery, server selection, and request-redirection. These techniques are exercised to alleviate imbalanced load conditions, while minimizing operational cost. The developed techniques and proposed models are evaluated through discrete-event simulation analysis, as well as empirical measurement study on the global MetaCDN Content Delivery Cloud testbed (www.metacdn.com).
