Embodiment Construction
[0074] The TCP congestion control method and device provided by the present invention will be described in more detail below with reference to the drawings and embodiments.
[0075] Embodiments of the present invention provide a TCP congestion control method, such as figure 1 shown, including:
[0076] Step 101, when it is determined that the current RTT period ends and the congestion state machine is in the Open state, determine the RTT value of the current RTT period and the congestion window of the current RTT period.
[0077] Specifically, the states of the TCP congestion state machine include: a default (open) state, a disordered (disorder) state, a packet loss (loss) state, a recovery (recovery) state, and the like. Among them, when the TCP state machine is in the Open state, there will be no packet loss and network congestion in the network. Packet loss and network congestion will not occur in the slow start phase of TCP congestion control, and packet loss may or may ...
