Video conferencing is now widely used both in wired and wireless network. Quality of Service (QoS) depends upon the efficient utilization of the network bandwidth. Internet Protocol (IP) multicasting is simultaneous transmission of data to multiple destination. IP multicast uses one-to-many technique, wherein a single packet is sent to multiple destinations in a multicast group identified by a single IP destination group address. Core failure is a serious issue in multicast networks with the QOS diminishing even if alternative routes are available. This paper investigates the performance of streaming data which require stringent QOS using unicast and multicast communication with Protocol Independent Multicasting - Sparse Mode (PIM-SM).
