Jabarkan Clos's nonblocking switch algorithm dari Sentral telepon dalam bahasa sunda

The scarce resources in a telephone switch are the connections between layers of subswitches.  The control logic has to allocate these connections, and most switches do so in a way that is fault tolerant.  See nonblocking minimal spanning switch for a discussion of Charles Clos's algorithm, used in many telephone switches, and arguably one of the most important algorithms in modérn industry.
