Switching Network
In circuit switching circuit is established between the two ends. It provides a dedicated path for data to travel from one to the other end. Resources are reserved at intermediate switches which are used during the transmission
The advantages of Circuit Switching is that
A well defined and dedicated path exists for the data to travel.
There is no waiting time at any switch and the data is transmitted without any delay.
Data always reaches the other end in order.
Circuit switching has the following disadvantages-
The channel is blocked for duration of transmission.
It is inefficient in terms of utilization of system resources.
The time required for establishing the circuit between the two ends is too long.
It requires more bandwidth and is more expensive
