An end-to-end QoS and security joint management for IPTV service delivery
Résumé
Today, the IPTV technology is emerging as a new concept for delivering and accessing audiovisual services over IP networks. To allow the transmission of IPTV services on wired and wireless networks, different issues should be overcome regarding scalability, quality of service (QoS) provisioning, security guaranty and terminals heterogeneity. In the IPTV architecture, QoS and security constitute two needs that have to be tightly managed. In this paper, we propose a complete end-to-end architecture for providing IPTV services. This architecture enables managing end-to-end QoS and security, while addressing other issues like the terminal heterogeneity. At first, we describe the architecture which is composed of two segments: the core network and the access network. Then, we detail the different mechanisms which allow managing simultaneously QoS and security for the IPTV streams delivered to heterogeneous mobile terminals. Performances evaluation demonstrates the importance of the joint management of security and QoS.
