Write the types of packet switching.
There are two types of packet switching as mentioned below:-
-
Virtual Circuit Based Packet Switching: In this mode of packet switching, for each packet we establish the virtual circuits. Each packet is then transmitted through the predestined route. In this mode we find similar phases as in the circuit switching method.
-
Datagram Based Packet Switching: In this mode of packet switching, every packet has two parts. They are known as a header and a payload.
