This traditional type of transmission methodology has remained in use, while other newer methods continue to evolve. If a source sends a packet and there is a delay of a few minutes before another packet can be sent, the resources can be reallocated during these minutes for other packets from other sources. Circuit switching network establishes a fixed bandwidth circuit channel between nodes before the users may communicate, as if the nodes were physically connected with an electrical circuit.
