Self-adaptive congestion control method for dynamically adjusting gain coefficient
ActiveCN111683393AImprove resource utilizationReduce network stressNetwork traffic/resource managementAdaptive congestion controlSelf adaptive
The invention discloses a self-adaptive congestion control method for dynamically adjusting a gain coefficient. A target value reflecting a network condition is calculated by stages; the congestion condition of a current network is determined according to the target value of the network condition reflected in each stage, and the sending rate gain coefficient at a subsequent moment in the network is adaptively adjusted based on the congestion condition of the current network, so that the sending rate can be adaptively adjusted according to the change of the network, and the transmission rate ofthe network is made relatively high. Besides, the ratio of the mean value to the variance is calculated to determine whether the current network is a wired network or a wireless network. According tothe method, adaptive switching in a wired or wireless network environment can be realized, and different minimum round-trip delays are switched according to different network environments to serve asreferences for measuring the network condition, so that the difference between the estimated congestion window value and the actual link capacity is relatively small, and the waste of network resources is avoided.
