The invention discloses a self-adaptive heavy hter detection method for a programmable switch. The self-adaptive heavy hter detection method is combined with a network measurement method based on state measurement and flow measurement to realize self-adaptive heavy hter detection. Based on the state information regularly obtained from the state measurement module, the most suitable measurement tasks for different time slices can be given, and the flow measurement module is called to dynamically select the corresponding processing logic to detect the specific head hter. In addition, through a method of adding an accurate statistical flow table, the measurement accuracy can be improved to the limit under the condition of less memory occupation, and the types of the measured head hters are further effectively distinguished. According to the method, a real network topology is established, and the feasibility of the method is verified by using a real network flow data set containing various heavy hitter flows. 本发明
