Multicasting is the delivery of a message or information to a group of destination computers simultaneously in a single transmission from the source. The copies of the messages are automatically created in other network elements like routers but only when the topology of the network requires it. Multicast is implemented most commonly in IP multicast which is further could be employed in internet protocol applications of streaming media. In the IP multicast the implementation of the multicast concept occurs at the IP routing level where routers create optimal distribution paths for datagram sent to a multicast destination address. At the Data Link Layer, multicast describes one-to-many distribution such as Ethernet multicast addressing, Asynchronous Transfer Mode (ATM) point-to-multipoint virtual circuits (P2MP) multicast. In this paper we have compared various multicasting mechanisms. The comparison is done on the basis of various factors like complexity, overhead, maintenance, etc. The mechanisms that are part of the paper are a secure ALM P2P multicasting technique for large scale networks using face recognition, IP multicasting techniques and the overlay multicasting techniques. The comparison of these multicasting techniques will help us to design and Implement a Secure Application-Level Multicasting (SALM) P2P Overlay Multicasting for large Scale Network. The main objective of the paper is to discuss all the three above mentioned multicasting phenomenon's and compare them on the basis of certain criterion so as carved out the best of all which can be further used for designing a secure multicasting technique which can take the best features of all combined together so as to get effective and efficient technique for multicasting the throughput of the network by effective and efficient delivery of the information to all the members of the group. The certain findings can be carved out of the comparison can help us to create a multicasting technique with less incurring of delays so that information can be delivered in limited time span and multicast path length so that efficient paths should be used so as to enhance performance in multicasting. Moreover in this paper we will study & investigate other issues that degrades the performance of Multicasting Techniques for large Scale Network and later we will come to know through the comparison that which technique performs well in these harsh environment and give effective results.
