We propose an autonomic QoS and QoE management architecture based on causal graphs for IPTV services over IP access networks. Our solution achieves a global self-diagnosis process based on local knowledge of each network element using a model-based diagnosis approach. We illustrate this novel approach in an IMS platform and detail the corresponding causal graph and diagnosis process for IPTV services.

“…La función de control (SCF) es un SIP AS que proporciona los parámetros de la red que el UE requiere para activar el servicio IPTV incluyendo el canal de entrega y control de contenido, también es responsable de la autorización de productos durante el inicio y modificación de la sesión. Esta autorización incluye la comprobación de los perfiles de usuario para determinar el nivel de privilegios que posee [10].…”

RESUMENLa televisión digital ha evolucionado continuamente desde su presentación digital terrestre (DVB-T), pasando por el estándar satelital (DVB-S) hasta llegar a su presentación actual conocida como IPTV (Internet Protocolo Television) que ofrece múltiples servicios multimedia tales como voz, video y datos, transportados con ciertos niveles de calidad de servicio, seguridad, interactividad y confianza gracias a la utilización de la pila de protocolos TCP/IP. En tal sentido el artículo pone a disposición de la comunidad académica una propuesta metodológica inicial que pretende servir de guía en la implementación de este tipo de sistemas sobre una plataforma de libre distribución conocida como IMS (IP Multimedia Subsystem) para redes de área local tipo IPv6. ABSTRACTDigital television has continuously evolved since its digital terrestrial appearance (DVB-T), passing through the satellite standard (DVB-S) until reaching its current presentation known as IPTV (Internet Protocol Television), which offers many multimedia services such as voice, video and data, that are conveyed with certain levels of quality of service, security, interactivity and reliability through the use of the TCP/IP protocol stack. In this sense the article provides to the academic community a preliminary methodological proposal which focuses on working as a guidance in the implementation of such systems on a platform of free distribution, known as IMS (IP Multimedia Subsystem) for IPv6 type local area networks.

“…The media delivery in a standard IMS architecture, for example, is carried out by what is known as the Media Resource Function (MRF), consisting of two distinct parts, namely the MCF (Media Controller Function) and MDF (Media Delivery Function) [2]. The ViE specification also has a similar component for media control, which is to be implemented by a Media Control (MC) server and the media delivery unit to be implemented by a fully-fledged Media Sever (MS).…”

As the IMS provides session establishment, QoS parameter negotiation, authentication and accounting it is an overlay architecture well qualified for session signaling concerning video in everywhere scenarios. The management of the signaling can be integrated as an application into a home media gateway (HMG) server. Heterogeneous mobile devices working with the diverge of codec leads to signaling disconnection because of parameter mismatch. The HMG server is further responsible for all necessary media signaling towards a proper media server to support the interoperation so that it can identify the disconnection because of SDP parameter mismatch further modify the SDP parameter to establish the connection. HMG also convert the media payload from one format to another so that user equipment able play the video streams. The media signaling requires a dedicated session description and can be provided by SIP or RTSP. This paper proposes a general IMS-based framework for delivering video in everywhere services over several access networks and presents the corresponding signaling flows for on-demand as well as live video calls. It further presents an approach for using SIP and RTSP in cooperation for realizing video on demand scenarios.
