TV Audience Fragmentation: Measurement, Causes, And Economic Consequences
<p>Modern video distribution has increased the quantity and variety of programming available to viewers. Multichannel broadcasters using high-bandwidth distribution mechanisms such as satellite and cable television are able to deliver hundreds of channels to each home. Video on demand (VOD) allows …

Optimal Link Utilization and Enhanced Quality of Service Using Dynamic Bandwidth Reservation for Pre-recorded Video
Video-on-Demand (VoD) is a service that allows people to request and view stored videos or movies of their choice directly online from a VoD service provider. The selected streaming videos are then delivered over the broadband Internet. The bursty nature of Variable-Bit-Rate (VBR) compressed video …

Optimization in stochastic models of network applications
In this dissertation, we propose stochastic models and develop optimal or near-optimal algorithms for resource allocation, for two important network applications: 1) video-on-demand (VoD) services in content distribution networks (CDNs) and 2) online advertising. For the first application, we …

Architectures and technologies for quality of service provisioning in next generation networks
A NGN is a telecommunication network that differs from classical dedicated networks because of its capability to provide voice, video, data and cellular services on the same infrastructure (Quadruple-Play). The ITU-T standardization body has defined the NGN architecture in three different and …

Single video performance analysis for video-on-demand systems
We study the content placement problem for cache delivery video-on-demand systems under static random network topologies with fixed heavy-tailed video demand. The performance measure is the amount of server load; we wish to minimize the total download rate for all users from the server and maximize …
