Question
Corresponding to Advanced Exercise 25 on page 324. Discuss what is incorrect with the following logic: Packet switching requires control and address bits to be added to each packet, which causes considerable overhead in packet switching. In circuit switching, a dedicated circuit is set up and no extra bits are added. Both of the following statements (A and B) are false.
A Therefore, there is no overhead in circuit switching. Here as the circuit-switched network are used more and more for data connections, two weaknesses become visible.
B Because there is no overhead in circuit switching, line utilization must be more efficient in circuit switching than in packet switching. There are four issues to consider, description of each issue is worth 2 points.
Explanation / Answer
Solution:
In Packet Switching the overhead information for routing is individual and unique to the data packet.
