1. ABSTRACT Content Distribution Networks (CDNs) have aided web servers in dealing with hot spots by replicating popular content on servers close to the clients. Typical CDNs are static in nature and as such, do not be able to react well with changing client viewing trends. This paper outlines the design of a Video Content Distribution Network (VCDN), which(More)
Personal Video Recorders (PVRs) such as TiVo have become very popular in recent years due to their ability to intelligently record TV content and make it accessible in an on-demand fashion to its users. Our research looks at providing a globally accessible storage architecture where all content broadcast over a period of time is available for streaming. Our(More)
Content Distribution Networks (CDNs) are used extensively on the WWW to relieve hot spots and reduce client latency when delivering web documents, but recently their role has been extended to the delivery of streaming multi-media content. Efficient placement of replicas in a CDN is very important, particularly when the content is large in size as is the(More)
Digital video recorders (DVR) such as TiVo (Tivo, 2005) are changing the way TV is being viewed. The ability to intelligently record content and provide an easy use play-back facility has meant that no longer is the viewer restricted to the TV broadcaster's schedule, but can now watch the program at anytime (after broadcast) with the addition of commercial(More)
In ad hoc networks that employ source-based on-demand routing, network nodes can use information contained in packet headers to populate a link cache. Given sufficient route requests and network traffic, a link cache will provide a good view of the spatial network topology in the past. This view can be successfully applied to making future routing decisions(More)
