Performance of Video Conferencing in Unicast and Multicast Communication Using Protocol Independent Multicast Routing
With video conferencing becoming extremely popular in wired and wireless network, efficient utilization of the network bandwidth is important to achieve Quality of Service (QOS). Internet Protocol (IP) multicast is a routing technique that allows IP traffic to be sent from one source or multiple sources and delivered to multiple destinations. Instead of sending individual packets to each destination, a single packet is sent to a multicast group, which is identified by a single IP destination group address. In this paper, it is proposed to compare the performance of video conferencing using unicast and multicast communication using Protocol Independent Multicasting – Sparse Mode (PIM-SM) modes.
