Multicast Security

Computer Engineering electronics Engineering Civil Engineering

As internet continues to grow phenomenally, the desire for more efficient ways of distributing information across network is increasing. Multicast technology is used for distributing data to a group of participants by conserving bandwidth more efficiently than traditional unicast mechanism. This is done by replicating IP streams in the router at the same time thus achieving better delivery to multiple users. This would mean conservation of computational resources of the sender and bandwidth efficiency in the network .A group membership can be performed using the Internet Group Multicast Protocol (IGMP) protocol. It provides admission control operation such as "join" and "leave". Some examples of applications that take advantage of multicast technology are video conferencing, digital broadcasting, software distribution and electronic learning. The Figure 1 depicts an example of a multicast distribution tree where information from a single sender traversing to multiple receivers. loading..
