Based on the analysis of the statistical data of the media access times in a multiservices operator’s (MSO) media-on-demand network in one day, a random media access model was generated. Based on this media access model, an IPTV system was built, and several key issues, such as the throughput of central server and the cache ratio of the regional servers, and on content delivery policies were studied. The simulation result showed that the increasing throughput capability of the central server and the cache ratio of the regional servers can increase the QoS of the IPTV systems only when these parameters can not meet the requirement of content access regulation.
