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

Improving I/O Performance of Multimedia Servers
TL;DR: A new architecture for Media-on-Demand (MoD) servers is developed that maximizes the number of concurrent clients that a single server can support and reduces the communication protocol processing overhead by a factor of two.

A caching-based video-on-demand service in wireless relay networks
Fei Xie,Kien A. Hua +1 more
TL;DR: This work proposes using video caching in the wireless relay networks (WRNs) for video on demand (VoD) service and assumes the relay station (RS) of the WRNs is capable of caching a small portion of the ongoing video stream.

Optimal multicast smoothing of streaming video over the Internet
TL;DR: This paper proposes to multicast smoothed video over an application-level overlay network of proxies, and to differentially cache the video at the intermediate nodes (proxies) in the distribution tree, in order to reduce the network bandwidth requirements of video dissemination.

Hulu in the neighborhood
TL;DR: This paper presents a new system for a neighborhood-assisted video-on-demand service that reduces access link traffic by carefully placing VoD data across the neighborhood, and demonstrates that this approach can reduce the access network traffic that ISPs must provision for by up to 45% while still providing high-quality service.

Proxy-assisted scalable periodic broadcasting of videos for heterogeneous clients
TL;DR: This paper proposes a scheme to significantly reduce the waiting time of all heterogeneous clients, without the need for any additional backbone bandwidth, which uses a proxy buffer within video-on-demand systems using PB.

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.
