The Tertiary Level in a Functional Cluster-Based Hierarchical VoD Server

摘要

A Video-On-Demand (VoD) server provides video services to the end user, that can request a piece of video at any time, without any previously established timetable. The growing demand of such services suggests the design of flexible and scalable VoD servers, both in storage capacity and bandwidth. The tertiary level of a VoD server that is being implemented in top of a cheap Linux cluster, based on a hierarchical distributed architecture, using the functional programming language Erlang, is proposed in this paper.
