Internetworking of Content Delivery Networks Mukaddim Pathan

"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).
