• Source - 1 outlet, no inlets
• Sink - 1 inlet, no outlets
• Flow - 1 inlet, 1 outlet
• BidiFlow - 2 inlets, 2 outlets
• Closed - no inlets, no outlets
• FanInN - N inlets (N <= 22), 1 outlet
• FanOutN - N outlets (N <= 22), 1 inlet
• UniformFanIn - any number of inlets of the same type, 1 outlet
• UniformFanOut - any number of outlets of the same type, 1 inlet
• Amorphous - any number of inlets or outlets, but untyped.
