WebJun 10, 2024 · TCP Congestion Control: basic outline and TCP CUBIC algorithm. TCP congestion control is a fundamental part of this protocol and over the years has undergone a process of constant improvement through the generation of different versions, such as TCP Tahoe, Reno, Vegas, and so on. WebOct 7, 2024 · Fast recovery is taking a very short amount of time ~1RTT: it starts when 3 dupacks arrive, then the missing segment is retransmitted and ACKed, which takes one RTT. Of course it is slightly longer if more packets get lost. Usually, such figures do not depict fast recovery. physiotherapy huntingdon

WebDuring fast recovery, cwnd does not increase upon each duplicate ACK, so when A receives ACK 10, cwnd is still 5. After this, A enters congestion avoidance mode and cwnd increases by MSS/cwnd each time new data is ACKed. Thus, at each time, A increases cwnd by 1, until cwnd reaches 10.
