In spite of the attractiveness of Video-on-demand (VoD) services,
their implantation to the present has not been as widespread as could have been
desired due to centralized VoD systems have a limited streaming capacity and
its grown is costly. One level proxy-based systems have been proposed to
increase the system capacity but their scalability are still limited by the main
network bandwidth. Our investigation are focussed on designing a flexible
LVoD (large-scale Video-on-Demand) system capable of easy scaling with
limited costs, which can adapt its size to the needs of the system. To achieve a
scalable LVoD system, it is essential that the communications system
bandwidth is able to grow in keeping with system growth (with a reasonable
cost and limited loss of efficiency). To get these requirements we have
proposed a hierarchical tree topology based on the use of independent local
networks with proxies. To allow the system’s grow, the functionality of the
proxy has been modified in such a way that it works at the same time as cache
for the most watched movies, and as a mirror for the remaining movies. The
evaluation of these systems has been done using an analytical model. The
results shows that this architecture guarantees unlimited and low-cost growth
for LVoD systems, the VoD system capacity can easily be adapted to any
number of users and the system is fault-tolerant. |
