SCAMP stands for Scalable Multicast Protocol for Communication in Large Group, this paper discusses about a new multicast protocol for communication with in large groups over internet. Most of the protocols build either shared tree or source based tree. Source tree are one which the node sending the data are supposed to be their root, source based tree are been used in data delivery. Source tree are been initiated by the receivers. It also helps in reducing the traffic in different parts of the network.

While shared tree, routers in the Internet act as root of the trees and distribute the data between the members of the group which lies in this tree. The shared is also used for signaling process, it provides information on source to all other members in the tree. One of the main advantages of source-based trees is that they support high data rate and they support sparse group, the advantages of these two are taken together in the SCAMP.

SCAMP protocol builds both of the shared tree and the source based tree. So in overall these protocols helps in reducing the traffic over different parts of the network, cut down the processing cost of the router and also make use of the bandwidth by subdividing the load over the network. Multicasting in IP network allows the transmission of IP diagram to a set of host from a multicast group. The end-to-end delay in source based trees is almost half of that in a shared tree.

Since SCAMP protocol builds source-based trees for the delivery of data packets. A brief study about the modes of packet delivery and an overview of the existing multicast protocols in this paper so a new protocol which are able to support high data rate and sparse as well as dense multicast groups are been proposed through SCAMP in this paper.
