Following are some of the advantages of circuit-switched network over a packet-switched network:
• Circuit-switched networks are well suitable for real time services such as voice calls and video calls whereas packet-switched network are not suitable for real time services. They are suitable for handling data.
• In circuit-switched networks, the transmission link is pre-allocated without taking into consideration the demand whereas packet-switched network allocates transmission link on demand.
• In circuit-switched network, the bandwidth is reserved and so packets arrive within the bandwidth whereas in packet-switched network, the bandwidth is not reserved and so the packets may have to wait for their turn to be forwarded.
