The present application relates to the technical field of broadband speed measurement, and discloses a broadband speed measurement method based on a TCP protocol, which solves the problem that the existing broadband speed measurement method cannot meet the demand of an operator for local precise speed measurement of a user end and cannot accurately return a broadband speed measurement rate under different speed measurement servers and network environments.The present application first matches and counts speed measurement target messages through a kernel hook function, and excludes non-speed measurement data interference; then dynamically adjusts the ACK reply frequency and the TCP congestion window size according to the real-time sending rate of the speed measurement server, quickly adapts the network state to occupy the available bandwidth; finally, the IQR algorithm is used to eliminate outliers in the speed measurement result and calculate the effective average value, and finally the speed measurement result that conforms to the real bearing capacity of the broadband line is output, which meets the demand of the operator for local precise speed measurement of the user end.
