Circuit Switching

In this article we will discuss Circuit Switching, will make brief discussion on Circuit Switching, In last article we discuss about Packet Switching.

Packet switching is easier and more affordable than circuit switching. Since all the bandwidth can be used at once, packet switching is more efficient because it doesn’t have to deal with a limited number of connections that may not be using all that bandwidth.

Circuit switching is a connection-oriented network switching technique. Here, a dedicated route is established between the source and the destination and the entire message is transferred through it.

Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel through the network before the nodes may communicate. It contrasts with packet-switched networks, which break the communication into packets and then send those packets through the network independently of one another.

Example of circuitswitching: You pick up your land phone and dial your friend. At that point, the telco provider creates a dedicated circuit for that session and connects you to your friend’s telephone.

As the connection is dedicated it cannot be used to transmit any other data even if the channel is free. It is inefficient in terms of utilization of system resources. As resources are allocated for the entire duration of connection, these are not available to other connections.
