Analysis of QoS requirements for delivering IPTV over WiMAX technology

摘要

It is well known that the advances in Broadband technologies have made the Internet Protocol Television (IPTV) possible as a commercial service. These broadband technologies should be able to effectively deliver IPTV services with high level of quality of service. One of the Broadband technologies is WiMAX. WiMAX as a broadband technology is able to deliver different communication services, such as voice and video services over IP. The QoS for delivering IPTV services depends especially on network performance and bandwidth. There is an increasing trend to deploy WiMAX technology for offering those services. For adequate IPTV quality and good user experience IP/MPLS core and access network needs to provide guaranteed QoS. Following QoS parameters should be met in order to deliver IPTV over WiMAX without QoS degradation: bandwidth, losses and delays. These are main metrics to satisfy QoS requirements for offering IPTV. In this paper we will analyze the possibility of delivering IPTV services over WiMAX technology. At the end we will analyze in details QoS requirements for delivering IPTV over WiMAX using fuzzy logic.
