Question
According to Multicasting in the textbook below:
Where is says highlighted in the text, "It greatly reduces the number of messages that need to be transmitted as compared to multiple unicasting for each member, thereby optimizing the bandwidth utilization."
Would this be true or false and explain!
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. forwardingExplanation / Answer
The answer would be false as multicasting uses lesser bandwidth (or better bandwidth optimisation) as compared to unicasting. In multicasting, the same packet is simultaneously delivered to the multiple receivers. Compare this to the case of unicasting to multiple receivers, where a copy of the same packet is sent to each receiver.
For example, assuming a packet of size 10kb is being sent to 100 receivers. In unicasting, 100 different packets are sent, and the bandwidth used will be 10*100 = 1000kb. In multicasting, the same packet is sent to all the receivers. Hence bandwidth used is just 10kb.
I hope this adequately explains your question.
