Statistical Analysis of Multicast versus Instant Channel Changing Unicast IPTV Provisioning
Toni Janevski, Zoran Vanevski · 2008
Bandwidth is a key constraint for video distribution and hence, there is a strong incentive for analysis and modelling of IPTV service. In this paper we provide statistical analysis of IPTV traces measured from real-life IPTV pre-operational network. The main target was to determine the trade off between the multicast distribution of IPTV and ICC (Instant Channel Changing) unicast distribution of this service to the end users. The results showed that multicast and unicast IPTV traffic have different self-similarity degrees, where the multicast is shown to be less self-similar, while ICC unicast traffic showed middle level burstiness. The obtained results provide important information for service and network providers in the area of network design for IPTV provisioning.
