IPTV, or TV services delivered over a managed IP (Internet protocol) network, is expected to skyrocket in the next five years from four million subscribers in 2006 to a projected 103 million in 2011 according to a recent report by analyst firm iSuppli Corporation. IPTV is the highest bandwidth service ever deployed into the network.

Along with the rapid increase in subscribers, there are two amplifying trends that will pose significant challenges and opportunities to network designers: video-on-demand (VoD), and the shift to high-definition TV (HDTV).
