Question

Multicasting [9.8] is the process of transmitting messages from a source to m tiple recipients by using a single address known as a group address. It greatily reduces the number of messages thaf need to be transmitted as compare multiple unicasting for each member, thereby optimizing the bandwidth uti liza- tion. Multicasting is found to be an extremely valuable technology for videol audio conferencing, distance learning, and multiparty games that ar pated to be available with wireless capabilities in the near future e antici- icasting is performed either by building a source-based tree proach, for each source members of Ge or by using a core-based tree. In a source-based tree ap of the group, a shortest path tree is created, encompassing all the the group, with the source being at the root of the tree (Figure 9.14). In a core- based tree approach (Figure 9.15), a particular router is chosen as a core. Every source forwards the packet to the core router, which takes care of the packet to all members of the multicast group. forwarding

Explanation / Answer

Answer)

True.

Unicast optimizes the bandwidth utilization better than that of multicasting as it is a one-to-one communication among the client as well as client applications and in the multicasting there is no such direct communcation among the source and the destination.
