Multicasting can be done on a hub but a hub does not need it always. Configuring a router or switch to use multicasting requires that the router or switch be IGMP capable.
There are several benefits of using multicasting technology. One benefit is that multicasting optimizes network performance. Another benefit of multicasting is that the technology is directed towards distributed applications such as distance learning.
IGMP
The terms Unicasting and Multicasting are used in computer networks. By Unicasting we mean that the communication is a One-to-One communication,ie. one computer interacts with just one other computer. by multicasting we mean that it is a One-to-Many communication.ie the computer interacts with more than one computer on the network.
