−With backpressure, the receiving side's available capacity affects how the sender produces or transmits. Data flows from producer to consumer; a signal about whether more can be accepted travels upstream. TCP receive windows, waiting on an asynchronous queue, and stream demand address this problem in different units and execution models.
+With backpressure, the sender paces production or transmission according to the receiver's available capacity. Data flows downstream from producer to consumer, while signals indicating how much more can be accepted travel upstream. TCP receive windows, waiting on an asynchronous queue, and stream demand address this problem in different units and execution models.
