Analysis and Configuration Methodology for Video on Demand Services Based on Monitoring Information and Prediction

This paper presents an analysis and configuration methodology for video-on-demand services. Usually, two entities take part in this kind of services: a network operator and a content provider. The former provides an Internet connection and manages servers and proxies, whereas the latter generates the provided contents. All their possibilities of configuration must be based on an accurate service behavioural analysis which evaluates the quality and the quantity of resources, contents and subscribers. This analysis can be performed using monitoring information and predictions of a near future behaviour established by managers. To formalize both analysis and configuration, a methodology must be developed in order to help the service managers to attain a good performance and at the same time, make a profit for their companies.
