Explain your answer. Suppose that IP V6 is sent over a noisy wireless link. There are a 145 hosts in all. Give possible arrangements of subnet masks to make this possible. Explain the flaw in the following reasoning.
Packet switching requires control and address bits to be added to each packet.
This introduces considerable overhead in packet switching. In circuit switching, a transparent circuit is established. No extra bits are needed. Therefore, there is no overhead in circuit switching Because there is no overhead, line utilization must be more efficient than in packet switching. Consider a packetswitching network of N nodes connected in the following topologies.
