ABSTRACT:
In a communications system, a sending system and a receiving system have multiple data buffers. In response to an inquiry from the sending system, the receiving system transmits information which indicates the size and number of data buffers available in the receiving system. The sending system then begins transmitting data frames, which are placed into the buffers of the receiving system. When the receiving system removes all of the data from a buffer, therefore freeing it to accept additional data, it sends a signal to the sending system indicating this fact. The sending system counts such signals, and ensures that the number of transmitted data frames does not exceed the number of frames which have been removed from the receiver's buffers by more than the number of buffers which the receiver has.
