A dynamic distributed video on demand service

Abstract

The use of Internet services has become part of everyday life. The need for more advanced applications is increasing and solutions have to be provided in order to meet it. Multimedia information is becoming more popular. The connection bandwidth is not yet ready to cope with rising expectations for applications such as video on demand (VoD). We propose a way to implement such a service over a limited bandwidth/best effort Internet based network. Our proposal consists of the implementation of algorithms and the introduction of quality of service features on a network such as the Internet that inherently does not support such features. We propose two techniques for the implementation of an Internet based video on demand service. The first deals with the distribution of video titles on several video servers and is called the Disk Manipulation Algorithm (DMA). The second gives a dynamic nature to the service, imposes a virtual routing procedure to the system and is called the Virtual Routing Algorithm (VRA).
