Circuit Switching Block Diagram

Circuit switching is a process of connecting two points together in a network to form a dedicated physical circuit or path. Using circuit switching, data flows continuous and uninterrupted between the two endpoints over the established path. Numerous voice and data communications applications depend on reliable circuit switching for their dependability and speed.

To better understand the working of circuit switching, let’s take a look at a circuit switching block diagram. The diagram shows the sequence of steps followed to establish a connection between two network nodes. Firstly, an initial request is sent from the originating node to the terminating node for establishing a connection. The two nodes then exchange setup messages containing the connection details. Once the source and destination of the connection are established, a link is set up with their respective circuit switching tables at each side.

The next step involves message routing, which is a process of finding the best route through the network for the connection. This is done by going through the available links and identifying the most efficient one. After that, the link is connected and acknowledgment messages are sent in both directions to establish network synchronization. Finally, the data transmission or signaling messages flow between the two nodes.

Unlike packet switching, circuit switching performs the resource-intensive connection setup process before data transmission takes place. This helps in creating a dedicated physical path, resulting in improved speed and latency. However, it can also lead to certain issues such as increased network congestion due to dedicated resources being locked while the connection is active.

Overall, circuit switching is an important telecommunications technology, enabling dedicated communication paths between two nodes. It is used extensively in networking applications such as telephony and video streaming. Understanding the working of the circuit switching block diagram is essential to appreciate the connection setup process.
