Computer Network | Circuit Switching VS Packet Switching






In circuit switching there are 3 phases
i) Connection Establishment.
ii) Data Transfer.
iii) Connection Released.


 In Packet switching directly data transfer takes place .

In circuit switching, each data unit know the entire  path address which is provided by the source


 In Packet switching, each data unit just know the final  destination address intermediate path is decided by the  routers.

In Circuit switching, data is processed at source  system only


 In Packet switching, data is processed at all intermediate  node  including source system.

Delay between data units in circuit switching is  uniform.


 Delay between data units in packet switching is not uniform.

Resource reservation is the feature of circuit  switching because path is fixed for data  transmission.


 There is no resource reservation because bandwidth is  shared among users.

Circuit switching is more reliable.


 Packet switching is less reliable.

Wastage of resources are more in Circuit Switching


 Less wastage of resources as compared to Circuit Switching
