An IPv6 Flow Label Based Approach for Mobile IPTV Quality of Service

摘要

The latest experiences hint that the QoS (Quality of Service) approaches adopted by IMS (IP Multimedia Subsystem) technologies are still suffering from a primary containment factor due to the nondifferentiation between IPTV (Internet Protocol Television) video components. IMS system also cannot ensure high IPTV data transfer due to the limitation of available cellular bandwidth. In this paper, we try to merge the advantage of high bandwidth assigned to LTE (Long Term Evolution) and a new PHB (Per-Hop Behavior) that classify and differentiate between IPTV sub traffics by using IPv6 Flow Label. This new architecture permits high-quality IPTV video components with the capability to prioritize the sub traffic according to the network administrator policy. The proposed architecture is implemented using OPNET software. The results show that IPTV users receive high-quality video data with a change in quantity according to data priority.
