Link flooding attack processing method and device, equipment and storage medium

The embodiment of the invention provides a link flooding attack processing method and device, equipment and a storage medium, and the method comprises the steps: obtaining an ICMP message, and calculating an information entropy value of the ICMP message; under the condition that the information entropy value is smaller than a preset early warning threshold value, positioning according to the information entropy value to obtain a congested link; obtaining current state information of the congested link, and inputting the current state information into a deep reinforcement learning model obtained by training historical state information and a historical routing strategy through a convolutional neural network and a Q-learning algorithm to obtain a current routing strategy; and performing routing processing on the link flooding attack according to the routing strategy. According to the embodiment of the invention, the method can achieve the detection of the link flooding attack under the condition of not increasi
