Currently IPTV services are rapidly being deployed, and scalable multicasting is required for the need of IPTV services, e.g. robustness, security, and QoS. While native IP multicast is considered a good solution for IPTV services, variety of overlay multicast mechanisms have been suggested to remove the barriers that block deployment of IP multicast on Internet. However, most of overlay multicast mechanisms do not consider host group model, which is not a problematic portion, but advantageous feature of traditional IP multicast in terms of scalability, robustness, and security. Thus, overlay multicast based only on end-hosts may suffer inefficiency such as long data transmission delay, large stress and stretch, which may result in lack of QoS required by IPTV receivers. In this paper, we propose a hybrid scheme to take advantages of both IP multicast and overlay multicast, based on two principle design factors. By adopting host group model and topology awareness, our scheme can inherently acquire network topology information used to get rid of inefficiency of application level routing, and to gain additional efficiency for many group members on subnet dense mode. Overall network performance enhancement is shown in the performance analysis of our scheme, regarding low latency, small stress, and optimal stretch for IPTV receivers in subnet dense mode.
