TLDR
This study investigates a novel multicast technique, called Skyscraper Broadcasting (SB), for video-on-demand applications, and is able to achieve the low latency of PB while using only 20% of the buffer space required by PPB.Abstract:
We investigate a novel multicast technique, called Skyscraper Broadcasting (SB), for video-on-demand applications. We discuss the data fragmentation technique, the broadcasting strategy, and the client design. We also show the correctness of our technique, and derive mathematical equations to analyze its storage requirement. To assess its performance, we compare it to the latest designs known as Pyramid Broadcasting (PB) and Permutation-Based Pyramid Broadcasting (PPB). Our study indicates that PB offers excellent access latency. However, it requires very large storage space and disk bandwidth at the receiving end. PPB is able to address these problems. However, this is accomplished at the expense of a larger access latency and more complex synchronization. With SB, we are able to achieve the low latency of PB while using only 20% of the buffer space required by PPB.read more

Video-on-demand: scalability and QoS control
TL;DR: This chapter proposes a novel scheduled multicast scheme based on a time-dependent bandwidth allocation approach, a Trace-Adaptive Fragmentation (TAF) scheme for periodic broadcast of Variable Bit Rate (VBR) encoded video, and a Loss-Less and Bandwidth Efficient (LLBE) protocol for periodic Broadcast of VBR video.

Pseudo Harmonic Staggered Broadcasting method for efficient Video on Demand service
TL;DR: The numerical results demonstrate that viewer's waiting time of the PHSB method converge to that of harmonic method as the bandwidth is increased and the client buffer requirements of this can be decreased below that of the staircase method by adjusting a short front part of a video size.

An Effective Batching Scheme Combining Static Multicasting with Dynamic Multicasting for Mobile IPTV
TL;DR: A scheme improving the existing batching scheme that applies dynamic multicasting during the interval of successive transmissions of the segments, and needs to store only a small number of segments in the mobile node for continuous playback is proposed.

A workload adaptive scheme for zero-delay video-on-demand service
TL;DR: Simulation results show that the workload adaptive scheme adapts nicely to the changing request rate and improves the performance of VOD service significantly in terms of total server bandwidth requirement.

Enhanced bespoke data broadcasting scheme for popular videos
TL;DR: The enhanced bespoke scheme is proposed, which provides the video data in time and its performance for the user's waiting time is better in comparison to that of the conservative staircase scheme.

Scheduling policies for an on-demand video server with batching
TL;DR: It is shown that an FCFS policy that schedules the movie with the longest outstanding request can perform better than the MQL policy that chooses the film with the maximum number of outstanding requests.

TL;DR: This paper provides analytical and experimental evaluations of pyramid broadcasting based on its implementation on an Ethernet LAN, gaining a radical improvement in access time and bandwidth use by using storage at the receiving end.

Dynamic batching policies for an on-demand video server
TL;DR: It is shown that a first come, first served (FCFS) policy that schedules the video with the longest outstanding request can perform better than the maximum queue length (MQL) policy, and multicasting is better exploited by scheduling playback of the most popular videos at predetermined, regular intervals (hence, termed FCFS-n).

On optimal batching policies for video-on-demand storage servers
TL;DR: This study proposes a batching policy that schedules the video with the maximum factored queue length and shows that MFQ yields excellent empirical results in terms of standard performance measures such as average latency time, defection rates and fairness.
