Özet:

Multimedia applications over the Internet and Internet Protocol Television (IPTV) gain a lot of attention. IPTV has a number of service requirements such as; high bandwidth, scalability, minimum delay, jitter and channel switch time. IP multicast, IMS (IP Multimedia System) Protocol and peer-to-peer approaches are proposed for implementing IPTV. However, IP multicast requires all the routers in the core network to possess multicast capability, IMS does not easily scale and P2P cannot e ciently utilize the network resources because of its completely distributed nature. To this end, we propose new application layer multicast protocol Cluster Based Application Layer Multicast IPTV (CALMTV) which combines application layer multicast, scalable video coding and probing techniques to meet IPTV requirements. We present the components and their relevant algorithms and evaluate the performance of CALMTV with ns2 simulations. Our results compared with the published results of other IPTV architectures show that CALMTV has better performance in end-to-end delay and zapping time.
