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

Hybrid Video Transmission Scheme for Minimizing Maximum Waiting Time in Video-on-Demand (VOD) System
TL;DR: An algorithm using binary search and combining broadcasting with unicast is proposed to minimize the maximum waiting time based on this property and a recommendation algorithm is applied in this algorithm which utilizes the cache of user to reduce the waiting time further.

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.
