Abstract
A system and method for controlling data transmission between two network elements. A first port of a transmitting element is coupled to a second port of a receiving element. The second port includes buffers for temporarily storing received data until the data can be sent to another element. Included in the transmitting element are a received-currently-full register (RCFR), a sent-and-not-received register (SANRR), and a buffer-busy register (BBR). The transmitting element checks its BBR to determine if a buffer in the receiving element is available. The availability of buffers can be determined using a single priority protocol or a multiple priority protocol. If a buffer is available, the transmitting element transmits a data frame to the receiving element and sets the SANRR and the BBR to indicate that a frame has been sent (and that no acknowledgment has been received), that the selected buffer in the receiver is full, and that no additional data frames are to be sent to this buffer until the buffer is empty. When data is received by the receiving element, it is sent to an available buffer. When the data is received by the buffer, the receiving element sets a bit in a currently-…
