Abstract
One embodiment of the present invention provides a system that facilitates transmission buffer under-run protection. During operation, the system stores bits of a data frame in a transmission buffer associated with an output port. The system also monitors the state of the transmission buffer and commences transmission of the data frame to the output port prior to complete reception of the data frame in the transmission buffer. The system further determines that the amount of data stored in the transmission buffer is below a predetermined threshold and inserts a number of predetermined unique bit sequences after the partially transmitted data frame, thereby allowing a receiving device to temporarily suspend reception of the data frame and resume reception at a later time without dropping the data frame.
