Design of Optical Content Distribution Networks for Video on Demand Services

DotSlash - Creating Content Distribution Networks on Demand

Traditional content distribution networks, such as Akamai, are well-suited for static web services that routinely experience large traffic volumes. They are unsuited for active content, i.e., content generated by scripts from databases, and web sites that are unlikely to receive significant number of requests. However, a few such sites will invariably experience their “fifteen minutes of fame”,...

Distribution of Video-on-Demand in Residential Networks

In this paper, we study how to distribute cache sizes into a tree structured server for transmitting video streams through video– on–demand (VoD) way. We use off-line smoothing for videos and our request rates are distributed according to a 24 hour audience curve. For this purpose we have designed a slotted-time bandwidth reservation algorithm, which has been used to simulate our experiments. O...

Eecient Video Allocation for Video-on-demand Services

A Video-on-Demand (VOD) server needs to store hundreds of movie titles and to support thousands of concurrent accesses. This, technically and economically, imposes a great challenge on the design of the disk storage subsystem of a VOD server. Due to diierent demands for diierent movie titles, the numbers of concurrent accesses to each movie can diier a lot. We deene access proole as the number ...
