Designing A Video On Demand Server - College Paper

Designing A Video On Demand Server

Video-on-demand (VoD) service will allow customers to request that certain movies or television shows be played on their television sets or computers immediately, giving individuals direct access to the materials stored in a video server. The goal of this project is to design a Video-on-Demand Server capable of performing to the following specifications:
ˇ Capacity - 25 feature-length movies
ˇ Serve 4 different movies simultaneously
ˇ No loss of video/audio
ˇ No "stutter" or skip
ˇ 100% fault tolerance

As previously discussed in the cost estimate, the Video on Demand (VoD) Server will be based on a multi-processor x86 architecture. The VoD server with all elements described in the ...

transfer speed, a 64MB hardware disk cache will also be used in the system. Arrays of optical drives will also be employed as secondary storage. The VoD Server will be linked to an array of Uninteruptable Power Supplies (UPS) capable of supplying 10 minutes of backup power.

Similar servers were tested in this configuration with multiple client access and was able to saturate the network with 150 clients playing MPEG1 and 2 streams. The effective network usage was 25 Mbits/sec. However, the network is saturated at this level due to the overhead associated with the TCP protocol. I expect CPU utilization vs. number of clients to be nearly linear as the number of clients increase.

In the following pages, I will discuss the qualities of an effective video server. Furthermore, I will also discuss the qualities of the video server which I have designed for this project.

processing, i.e., the common point of failure. In this case, when an autonomous server fails, all the clients being served by it are affected. In the case of the distributed paradigm, if we assume that some loss of data can be tolerated at the cost of reduced Quality of Service (QoS) to the clients then when a server fails all the clients being served by the distributed system are affected as they all have a part of the encoded stream stored on the faulty server.

One of the driving forces behind the distributed server paradigm is the concept borrowed from Redundant Arrays of Inexpensive Disks (RAID). In order to serve a large number of clients from a VoD server, the server ...
