=== Garbage bytes === | |||
Garbage bytes are single bytes sent as part of TCP keep alive packets that have already been acknowledge before by the receiver the data. Some TCP implementations sent single bytes as keep alive packets instead of just empty ACK packets. The retransmitted byte has already been acknowledge and may be the same or different as the original byte of the same sequence number. The TCP stack of the receiver will discard this byte. Technically it is a retransmitted byte, but since it is already acknowledge and will be discarded, we account this byte as a garbage byte to not show as part of regular retransmissions. | |||
