Disadvantage of Multiplexing
- It increase the complexity of the system
- There is a problem of SPoF(Single Point of Failure) that means if there is failure in singel point than the entire system become fails.
- This is not fault tolerant.
Multiplexing (Channel Sharing) in Computer Network
Multiplexing means multiple sources but one link. An alternative approach is a Direct point-to-point connection, but it has several problems as it requires an I/O port for each device, a need line for each device, and also a large amount of wiring needed if on different floors. Instead, if we use a multiplexer approach then all devices are connected to MUX and one line to the host, the link carries multiple channels of information and several lines equal to the number of lines out.
