Simulación y evaluación de una arquitectura IPTV de video en tiempo real, mediante software libre.

Abstract

The objetive of this project was to evaluate the main features in the televisión and video content service on demand, through the simulation of an IPTV architecture through free sotware. We identified the parameters at the network level that affect the QoS such as: Delay, variation of the delay (jitter), packet loss, bandwidth, as well as the type of protocol (RTSP and HTTP) used for the transmisión of the service, at the user level, these parameters affect the video display. Fort he simulation, two scenarios were carried out: the first a Multicasting network with GPON technology, the second a Multicasting network with ADSL technology using the free software Opnet Modeler that is now known as River Modeler, and the GNS3 software. From the results obtained, the IPTV Multicast architecture with GPON is much more efficient than an IPTV Multicast architecture with ADSL, since besides being a reliable and secure means it provides a higher transmisión speed reaching 1.2 Gbps in an uplink and the 2.4 Gbps in a downlink, has a lower delay wich indicates that the visualization of multimedia content is more fluid and efficient, allows a greater number of packets sent and received. In addition, it can be concluded that the HTTP protocol presented a better performance in comparison to RSTP, since it showed lower losses and lower delay.
