Análisis de la tecnología IMS (IP Multimedia Subsystem) y diseñar un servicio de transmisión multimedia de video mediante Open IMS Core para evaluar el tráfico Unicast y Multicast.

Abstract

The purpose of this work is to analyze the IMS Technology (IP Multimedia Subsystem), and design a multimedia video transmission service through Open IMS Core that allows to evaluate Unicast and Multicast traffic. A study of the IP Multimedia Subsystem (IMS) platform was conducted as a Service Delivery Platform in the adoption of New Generation Networks (NGN). A quasi-experimental and a cross-sectional design were proposed where the evaluation of Unicast and Multicast data traffic in the video streaming scenarios using Open IMS Core and using VLC is proposed. The inductive, deductive, analytical and scientific methods were used and the research approach is both qualitative and quantitative. The scope of the research is correlational. The two video streaming scenarios were evaluated by subjective observations from the point of view of the end user regarding to the quality of the video received using the Mean Opinion Score (MOS) method to quantify the impact that the presence of faults in the service has on users. Through the analysis of IMS technology, the design and implementation of the video streaming prototype was fulfilled according to the objectives set. Therefore, the application obtained specifies an example platform for the unification of future end-user services. Since IMS Core is an open source platform and is oriented mainly to the educational area, it is recommended to make the necessary analyzes so that it can be linked to educational platforms such as Moodle and informative ones such as Joomla, Drupal, etc.
