Question

between circuit switching approach and packet switching approach

1 which one used in Internet

2 which one provide performance guarantees, such as a guaranteed transmission rate?

3 which one requires setup work before data can be transmitted?

Answer 1

1. Packet Switching, The internet is based on the Packet-switching approach as some delay is acceptable here hence making packet switching a more suitable approach.

2. Circuit Switching, A dedicated path is established for a conversation in circuit-switching. Hence, minimizing the traffic and providing a guaranteed transmission rate.

3. Circuit Switching, In circuit switching, for complete conversation, 3 step setup is required. In the case of packet switching, we are able to directly transfer data since the source includes the Entire Path Address.
