1. |
Circuit Switching is done by setting a physical path between two systems. |
In message Switching, data is first stored by one node then forward to another node to transfer the data to another system. |
2. |
In circuit switching, data is not stored. |
In message Switching, data is first stored, then forwarded to the next node. |
3. |
Circuit Switching needs a dedicated physical path that’s why the messages need not be addressed. |
Message switching does not need a dedicated physical path and on Message switching, The messages are addressed independently. |
4. |
Circuit Switching is Geographical addressing. |
Message Switching is Hierarchical addressing. |
5. |
Circuit Switching is costlier than message Switching. |
The cost of message switching is less than circuit switching. |
6. |
Circuit switching routing is manual type routing. |
Message Switching routing is not manual type routing, here route is selected during call setup. |
7. |
Circuit switching reserves the full bandwidth in advance. because of that, there is a lot of wastage of bandwidth |
Message Switching does not reserve the entire bandwidth in advance. and that’s why bandwidth is used to its maximum extent. |
8. |
In-circuit switching, the charge depends on time and distance. |
In message switching, the charge is based on the number of bytes and distance. |
9. |
Congestion occurs per minute in circuit switching. |
In message switching, no congestion or very little congestion occurs. |
10. |
Circuit switching uses Analog and digital media on a variety of platforms. |
Whereas Message switching uses digital media on a variety of platforms. |
11. |
In-circuit switching there is no propagation delay. |
While In Message switching there is a propagation delay. |
12. |
The transmission capacity of circuit switching is very low. |
while the transmission capacity of message switching is high. |
13. |
In a circuit switching, Messages need not be addressed as there is one dedicated path. |
In message switching, Messages are addressed as independent routes are established. |
14. |
Ex. Real time transfer of voice signals. |
Ex. Transmission of telegram. |
