Multiplexing
Breaking up a higher speed circuit into several slower (logical) circuits
- Several devices can use it at the same time
- Requires two multiplexer: one to combine; one to separate
Main advantage: cost
- Fewer network circuits needed
Categories of multiplexing:
- Frequency division multiplexing (FDM)
- Time division multiplexing (TDM)
- Statistical time division multiplexing (STDM)
- Wavelength division multiplexing (WDM)
