CIRCUIT SWITCHING
|
PACKET SWITCHING |
|---|---|
|
In circuit switching there are 3 phases
|
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 |
