Sender sends message to receiver informing receiver of location of data to be moved. Using local software, receiver buffers message if there is no space for the data, otherwise receiver pulls (DMA reads) data from sender into local buffer. After receiving data, receiver sends message to sender to indicate successful data retrieval.
