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

Extension of practical channel transition broadcasting for near video-on-demand applications
TL;DR: An enhanced version of the practical channel transition broadcasting scheme, referred to as PCTB+ is proposed to cause less bandwidth waste and lower transition playback latency and outperforms the seamless fast broadcasting (SFB) scheme for bandwidth waste under most conditions.

Minimizing the Worst-Case Playback Delay in VoD Services over Passive Optical Networks
TL;DR: This work derives the minimum worst-case playback delay (WPD) for a given bandwidth available for VoD services in the PON, and design optimal patch scheduling algorithm as well as ONU rebroadcast and patching channel assignment to guarantee such minimum WPD.
Proxy Caching for Video on Demand Systems in Multicasting Networks
TL;DR: A wide-scale cost model for proxy caching is introduced that takes bandwidth consumption into consideration over an entire network for different multicasting tree topologies and quantifies the overall usage of network resources more accurately.

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.

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.
