Advanced multicast service scheduling mechanism with IGMP snooping in WDM-PON

In this paper, we deal with the multicast service management to efficiently support the broadcasting TV and the near real time high quality VoD (video on demand) service though the data communication networks. This is an emerging issue of the next generation network. Until now, several network architectures have been proposed but most of these have been concentrated on increase of the basic network bandwidth or induced the higher system complexity. The hybrid WDM-PON guarantees both kinds of traffic the independent and stable service by introducing the shared broadcast wavelength for multicast group traffic service. The proposed dynamic multicast group scheduling (DMGS) based on hybrid WDM-PON efficiently supports the common Internet traffic as well as the large number of multicast groups by maximizing the service share-index of registered multicast groups which uses the broadcast wavelength in real time
