Web proxies and Content Delivery Networks (CDNs) are widely used to accelerate Web content delivery and to conserve Internet bandwidth. These caching agents are highly e ective for static content, which is an important component of all Web-based services. This paper explores the e ect of ubiquitous Web caching on the request patterns seen by other components of an end-to-end content delivery ar...

The clustering of multiple video servers is a popular architecture for huge VOD systems. In a clustered VOD system, user requests are distributed among the video servers by the dispatcher.
