WebDec 9, 2024 · In particular, an average number of DupACKs is generated per arbitrary time interval (e.g., one second, five seconds, 10 seconds and so on), such that a metric denoted herein as a duplicate ACKs per second value (i.e., retransmission average of the TCP/IP flow) R A may be calculated as follows: WebHowever, if the number of duplicate ACKs reaches three, then the sender concludes that the packet has indeed been dropped, and it goes ahead and retransmits the packet (whose SN=duplicate ACK value) without waiting for the retransmission timer to expire. This action is known as Fast Retransmit. ... When set to 0, the router should not be ...

They're not just used for fast retransmissions, it is the other way around (sort of): fast retransmissions use a counter for duplicate ACKs to trigger a retransmission faster than by Retransmission TimeOut (RTO). If you see duplicate ACKs coming in ...
WebFeb 21, 2024 · Now, why doesn’t it wait for more than three duplicate ACKs to retransmit the dropped packet? Because if it waits longer, the RTO timer might expire.
