Types of Switching in Networking, 3 Types of Switching

Hello friends, welcome to Edifyclue today you are going to read about Switching, in this article you are going to read three different Types of switching and their advantages and disadvantages.

What is Switching

By exchange or sharing information from one computer to another or between different computer networks and networks, segments are called switching in Networking.

The process of switching is to redirect packets coming in from one port to the port leading towards the stopping place. Whenever the data comes on a port called Ingress, and whenever the data exit a port is called Egress.

Switching is divided into two different categories:

  • Connectionless: The data is forwarded in place of forwarding tables. No previous handshaking is required and acknowledgments are optional.
  • Connection-Oriented:  Before switching data to be forwarded to the destination, there is a requirement to re-establish a circuit along the path between both endpoints. Data is then forwarded to that circuit. After the transfer is done, circuits can be kept for future use or can be turned down immediately.

The message, circuit, and packet are the three types of switching. These switches have their own advantages and disadvantages that make them unique from others. So the first type of switching you are going to read about is Circuit Switching.

Types of Switching

There are three types of switching let’s find out something more about these.

  • Circuit Switching
  • Message Switching
  • Packet Switching

Circuit Switching:-

A circuit is the first type of switching, Whenever the two nodes transmit with each other on a devoted path, Known as Circuit switching.

To transfer the data all the circuits must be ready and established so that the transfer of data can take place.

Circuits may be permanent or temporary Those applications that use the circuit switching have to go through three phases.

  • Establish a circuit
  • Transfer the data
  • Disconnect the circuit
Types of Switching

Advantages 

  • There is no delay in data flow because of the personal transmission path.
  • A circuit is dedicated to the call- no disturbance and no sharing.
  • Quality of service guaranteed.
  • Full bandwidth for the duration of the call.

Disadvantages 

  • It was developed for voice traffic, not for data traffic.
  • during any pandemic, the network may be unavailable or unstable.
  • takes a long time to set up.
Message Switching:-

This is the second type of Switching, this is known as the alternate for a circuit before the packet was introduced.

In this switching End, users easily communicate by receiving and sending messages that include all data to be shared. smallest individuals units are called messages.

There are the two most important characteristics of a message-

  • Store and forward
  • Message delivery
 Types of Switching

Advantages

  • Efficient traffic management.
  • Priority may be used to manage network traffic.
  • Message can be stored in message switches whenever there is a problem in sending them.

Disadvantages

  • This is not suitable for real-time applications such as data communication, video, or audio.
  • this is not compatible with interactive applications.
  • Delay in storing and forwarding.
  • Costly intermediate storage.
Packet Switching:-

A packet is the third and last type of Switching, this is a type of connectionless network switching technique, a message is grouped and divided into a number of units called packets. there is no need to establish a dedicated circuit for communication.

 Types of Switching

Advantages

  • This is cost-effective because they don’t need a massive amount of secondary storage.
  • Many network users can share the same channel at the same time.
  • packets can easily be rerouted if there is any problem such as busy or disabled links.

Disadvantages

  • Heavy usage can cause delays.
  • Data packets can get lost or become corrupted.
  • Protocols are needed for reliable transfer.
  • More processing power for the switching devices.

Conclusion

Circuit, Message, and packet are the three different types of switching that are used today, they all have their own capabilities and disabilities. where the circuit gives no delay in data flow and messages are easily handle the more traffic and at the last packet can provide all these at very low cost.
