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.
