IPTV QoS and QoE measurements in wired and wireless networks

Internet Protocol Television or IPTV is a multimedia content delivery service that is increasingly proliferating in the consumers lives and a hot-topic for telecommunication companies to gain a share on consumers´ entertainment budget. This alternate method of distributing television content over IP requires a high level of network performance and guaranteed Quality of Service (QoS) in order for the end user to have an assured and high-quality viewing experience. Yet, the quality margins of IPTV are commonly put to test in almost all cases where customers re-distribute the service within their premisses. In this paper, our main motivation is to investigate how such real-life networks perform in terms of distributing this inelastic and high-bandwidth type of service utilizing traffic measurements. Furthermore, our goal is to verify and analyze whether these studied networks are well suited for multicast IPTV traffic.
