On extending open source IMS platform for integrated IPTV and VoIP services over IPv6

Even when IMS is the most popular platform for multimedia services, the open versions of IMS ecosystem are lacking in specified functionalities for IPTVv6 and VoIPv6 services. In this paper, we extend current client and server open source software in order to provide reliability and security to these multimedia services. As a part of our work the IMS architecture for conferencing system with proposed mechanisms to improve system availability is presented. The monitoring, based on local and remote mechanisms, gives an ability to fast and reliable failures detection. The proposed algorithm also includes load balancing of the original initialized and restored conferencing sessions on the MRF servers. The restoring mechanism relocates conferences with media mixing and management to one of the available media servers. Moreover, we put many efforts on adapting current IPv4-oriented software to IPv6 streaming. The importance of the presented results lie in the impulse offered to the multimedia services over IPv6, which are actually the main hindrance in IPv6 start.
