Many internet applications need live multimedia data to be transmitted over the network. To incorporate the same, applications like video conferencing and e-learning need IP multicast or unicast. However in internet applications, lack of multicast services play a deterrent role in group communication. When live multimedia data is transferred to more than one receiver over the network, the more number of duplicate packets are transferred. Due to this duplicate packets, bandwidth and other resources are not properly utilized. When network connection is slow then clustering duplicate packets takes place in link. Due to this clustering, there is a chance for the data loss to occur. A CacheCast mechanism can be used on the router to eliminate such type of duplicate packets. Cache is placed on the router which acts independently for the sender and receiver. In single source multiple destinations, while transferring live multimedia data to more number of receivers, the duplicate packets may occur on the link. All duplicate packets are removed at the nearest router of sender and retrieved from the nearest router of receiver. This technique is used to achieve the better utilization of bandwidth. When send the live data to more than one receiver, bandwidth is efficiently used and the receiver’s side original data has to be reconstructed without any discrepancies.
