Switching network :

Switching is the process of forwarding packets coming in from one port to a port leading towards the destination. When data comes to a port it is called Engress and when data leaves a port it is called Egress. A communication system may include number of switches and nodes.

Circuit Switching :

In circuit switching,A dedicated channel is set up for a single connection between the sender and receiver during the communication session. In telephone communication system,the normal voice call is the example of circuit switching. The telephone service provider maintain a unbroken link for each telephone call. Circuit Switching is pass through 3 phases,those are:

1. Circuit Establishment
2. Data Transfer
3. Circuit Disconnect

Packet Switching :

Packet switching is a method of grouping data which is transmitted over a digital network into packets. Packets are made of a Header and Payload. Data in the header is used by networking hardware to direct the packet to its destination where the Payload is extracted and used by application software.
