%X In this paper the Protocol Independent Multicast (PIM) protocol is being used. The PIM protocol avoids the packet drop and diverting problem. The PIM protocol is not dependent on any specific unicast routing protocol. It is IP routing independent protocol. The PIM uses the unicast and multicast information to create a distribution tree along the reverse path from the receivers towards the source. The PIM protocol consists of three modes such as sparse mode, dense mode and bidirectional mode. The sparse mode is used to sends the file from router to a receiver. The dense mode is used to sends the file from router to multiple receivers. The bidirectional mode is used to sends the message from router to sender and then continue the other process depending on the sender requirements. The client sends the file from sender to destination via the router. First the sender selects the file name and receiver name for transmission. Then the state is assigned automatically depend upon the user selection. The state can be defined by the number of destination selected to transmit the file from the source. If the sender selects single destination, it will assign ˇ°Without forwarding state routerˇ± for transmission. Otherwise it will assign ˇ°Forwarding state routerˇ± for transmission. If the receiver is not available, the router sends a message to sender such that ˇ°the requested receiver is not availableˇ±. Then the client will decide the file is transfer or not, it will reply with transfer the file, then the file will be transferred until the file will be discarded at client side. If the sender tries the same process after two times, the router will display the warning message as ˇ°the requested receiver is not available, this file will be discarded at client sideˇ±. Then it continues the other process.
