Difference Between Circuit Switching Network And Packet Switching Network
Circuit switching and packet switching both are methods of implementing communication channels between nodes in a network .However , there are differences in the communication approach.
| Circuit Switching | Packet Switching | |
|---|---|---|
| In circuit switching a dedicated communication channel is established . | In packet switching transmitted data is grouped into suitably sized blocks, called packets, that are transmitted via a medium that may be shared by multiple simultaneous communication sessions. | |
| A physical communication path is established for the entire session of conversation. | Route is established for each packet. | |
| It has fixed bandwith. | It has dynamic bandwidth. | |
| No overhead bits after call setup . | Overhead bits are present in each packet. |
