New Approach in Multimedia Conferencing System by Using Ipv6 Multicast: New Multimedia Conferencing System Based on Ipv6 Multicast Capability

Multimedia Conferencing is one of the major applications in the domain of networks that is being taken into consideration in the Internet. Multimedia Conferencing System (MCS) is widely used today as a communication tool over the Internet. Currently, the MCS uses a dedicated entity to deliver audio and video to multimedia conferencing participants over WAN or Internet called Multiple LAN Internet Protocol Converter (MLIC). This entity used IPv4 unicasting to deliver the audio and video. The work reported in this book proposes and implements a new MCS based on IPv6 multicasting capability. The new proposed system improves the video quality and uses less than 50% of bandwidth used by current MCS when more than 3 users participate in a conference. The mechanism used in this research conserves bandwidth and effectively prevent network congestion, especially for cases such as video conferencing that involve a large-volume data transmission. This research introduces the concept of IPv6, multicast mechanisms related to the principal, and the realization of MPEG video streams in the IPv6 multicast transmission line, any other video codec can be used with the same design.
