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
