Name	Type	Description
BackPressureBarrier	simple module	Prevents backpressure propagation from its output to its input and vice versa. It always allows pushing and pulling packets independently of what the connected modules would allow to do in their current state. Both pushed and pulled packets pass through unchanged, but the operations may raise a runtime error due to this module preventing backpressure propagation.
