This article proposed to variety of switching methods in communication networks such as Circuit Switching, Packet Switching, Cell-switching, Frame Switching and Message Switching. Switched methods of communication networks are those in which data transferred from source to destination routed between various intermediate knobs. Switching is the technique by which knobs control or switch data to transmit it between specific points of a network. Transmission between sender and receiver, called as circuit switching. When any network knob wants to send any type of information, a call request signal sent to the receiver and acknowledged. Cell switching handles both the digital voice and data signals. The frame switching either uses a permanent or switched virtual circuit to set the connection and enable the transfer of bit from source to the destination. Message switching network consists of transmission links (channels), store-and-forward switch knobs and end stations.

Circuit Switching, Packet Switching, Cell switching, Frame Switching and Message Switching.
