Dimensioning of IPTV VoD Service in Heterogeneous Broadband Access Networks

Abstract. The IPTV subscription rate has increased steadily since the introduction of IPTV Video on Demand (VoD) services. We have developed a model to determine the optimum deployment strategy for IPTV delivery network from the IPTV service providers' perspective. The analysis technique in this paper helps us determine the best deployment scenarios to support a certain number of customers within the tolerant boundary of Quality of Experience (QoE) measures. We define important QoE measures. The QoE will help service providers make deployment decisions including the number of servers, distance of servers from a community, and desirable access network bandwidth capacity
