Unicast, Broadcasting and Multicasting

Multicasting

Hi, this tutorial I am going to give you a basic idea of Multicasting. Before go in to the multicasting it is essential to know the function of the other related routing schemes of multicasting; such as Broadcasting and Unicasting.

Broadcasting: Which is the most popular routing scheme for every one because ones the data traffic arrive to the node (router) the router will send many copies to every nodes (routers) connects to it(shown in figure 1.5.1.a). It makes every user to access the traffic.

Unicasting: In this method after receiving the traffic to the edge router, the traffic is forwarding to the desired user edge router only. This make only that connected router users only to access.

 

Multicasting: The idea of Multicasting is transmitting the data traffic to the selected groups as shown in the following figure. In computer networking, multicast is the delivery of a message or information to a group of destination computers simultaneously in a single transmission from the source creating copies automatically in other network elements, such as routers, only when the topology of the network requires it.

 

Multicast is most commonly implemented in IP multicast, which is often employed in IP applications of streaming media and Internet television. In 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.

Hey, I think you guys got something for your knowledge. So please do some comments. I will be back with IP routing, Thank you
