Flow Control
Definition - Technique for ensuring that a transmitting entity, such as a modem, does not overwhelm a recieving entity with data. When the buffers on the receiving device are full, a message is sent to the sending device to suspend the transmission until the data in the buffers has been processed. In IBM networks the technique is called pacing.
