The need
for more advanced applications is increasing and solutions have to be provided in
order to meet it. Multimedia information is constantly getting more popular. The
connections’ bandwidth though is not ready yet to cope with the rising expectations of
applications such as Video on Demand (VoD), which are very consuming in terms of
bandwidth. In this paper 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 attempt to introduce Quality of Service features
on a network such as the Internet that inherently does not support such features. In this
paper we propose two techniques that can serve in the implementation of an Internet
based Video on Demand service. The first deals with the distribution of video titles on
the several Video Servers and is called Disk Manipulation Algorithm (DMA). The
second gives a dynamic nature to the service, imposes a virtual routing procedure to
the system and is called Virtual Routing Algorithm (VRA).1 aBouras, Christos1 aKapoulas, Vaggelis1 aKonidaris, Agis1 aSevasti, Afroditi  uhttp://telematics.upatras.gr/telematics/publications/dynamic-distributed-video-demand-service?language=el
